IOS virtual currency audit

4.

The future development trend of the Internet has the following possible directions:

1. Globalization trend. In the next 10 years and 50 years, the Internet will be globalized, which can not be achieved at present

2. Decentralization and flattening. From we media, we can see that we can pay attention to what we like. From e-commerce, we can also see that goods will go directly from manufacturers to consumers

3. Artificial intelligence is still at a relatively low level. Another 100 or 200 years may be the era of artificial intelligence. Artificial intelligence is a major trend of Internet development

5. This is necessary, and Apple store's review of virtual currency is relatively strict. Before bitcoin related software was launched in Apple store, it was very difficult. However, it is OK to exist in the form of integral, and it is feasible
for example, the token of decent, a decentralized content publishing platform, should be OK.

6.

1: Because the Central Bank of China defines bitcoin as a special Internet commodity and denies its monetary attribute

2: bitcoin cannot be used for payment. Therefore, bitcoin wallets cannot be used in the mainland, but they can be used outside the mainland

3: however, you can switch the apple store to Hong Kong or other regions to download bitcoin wallets, such as blockchain wallets, Bitai wallets, etc< br />

7. They are the usual means used by black platforms. They do it intentionally without giving money. As long as the account can log in normally, it can be solved

8. Basically, every IOS developer hopes that his or her works can soar like birds. Moreover, in the rankings, we can often see the shadow of Chinese works. But now there are nearly 400000 apps in the app store. Let alone being a bird, even entering the rankings is very difficult. So, how can we make it to the top
mining the rules of the leaderboard
first of all, of course, we should always pay attention to this straightforward and mysterious leaderboard, saying it is straightforward because everyone can see it, but saying it is mysterious because no one knows the rules behind the leaderboard except apple itself. The list can be seen on the IOS device or on the computer's iTunes: each country has its own list, which is divided into three parts, and each list now provides 200 proct lists
these three rankings are top paid, top free and top growing respectively. The first two existed when the app store opened, but the third was added almost a year later. We can roughly understand these three lists as the highest number of paid downloads, the highest number of free downloads, and the highest income, but the fact is much more complicated than that. If we observe the list for a period of time and refresh it every half an hour, we can find that the list is constantly changing. So is the change of downloads within half an hour caused the change of the list? We have no way to know that Apple has been adjusting its ranking rules. It has been estimated that it has something to do with the number of downloads and increments within a few days. In April of this year, the changes in the ranking made people wonder whether Apple increased the proportion of user activity. All this is speculation, but in any case, we can see that apple is virtually asking developers to make better procts
the strategy of making a list successfully
How can developers make their procts into the list after they have fully analyzed the list, determined the development direction of the procts, and made an excellent proct through excellent efforts? First of all, the most direct and effective way is to be recommended by Apple editors. After entering the recommendation list (recommended once every Friday, Beijing time), there will be more opportunities to impact the list. Last year, the proct "finger balance" from Shanghai coconants Island company was recommended to top paid 6. As for how to make recommendations, I consulted Apple's global developer relations director, whose answer was simple: "excellent works!" After all, the number of procts that can be recommended every week is limited, and even if they are recommended, the recommended position will also affect the efficiency of ranking. For example, it is also a game. If you enter the home page recommendation, you will have more opportunities than entering the game recommendation; It's also recommended on the home page. Naturally, those in the front have more exposure opportunities than those in the back. Unfortunately, no matter whether we can be recommended or not, and the location after being recommended, we developers can't control and predict at all. This is why many developers call the day when the recommendation list changes "magic Friday". Every week, apple gives enough exposure to excellent procts in this way, and so there are many examples of entering the rankings. Once recommended, in order to increase the success rate of the list, it is also a very effective way to temporarily lower the price of the proct. However, if you find that even if you rece the price, you can't make the list. In order to maximize the profit, you can change the price back, because the week of last recommendation is often the week with the highest income for developers. In the past, the effect of "recommendation" can last for one month, but with more and more procts, Apple will greatly shorten the cycle. Apple has been adjusting relevant strategies. As a developer, the best choice is to accept and adapt to changes
if the editor of Apple doesn't like the proct because of bad luck and other reasons, we need to use promotion to increase the exposure of the proct. According to the statistics of a number of data analysis companies, more than 90% of all users purchase IOS devices directly. Therefore, the promotion methods should also focus on the services for IOS devices. As for web advertising, the use of public relations companies and other means, it is not recommended for small studios, which will basically lead to the shortage of income
the simplest way to promote paid procts is to make a free version with limited functions
as early as 2009, ifigher, a legendary work from epicforce company in Hong Kong, pushed the paid version to the highest position of top paid 2 by rushing to the free version of top free 1, creating a myth of overseas developers. So the free version should be done in any case. As for whether it is launched before, after or at the same time, there is no fixed rule. Developers can decide according to the actual situation. The design point of the free version is to arouse the user's interest just right. Take ifigher as an example. The official version has four levels, while the free version has only one, but the effect is very good. If the free version gives three levels, some users will feel that it is not worth paying only for one level; In the same way, if the free version only has the front part of the first level, it is also inappropriate for users to end the game before they feel the fun of the game
because almost everyone is aware of the importance of free version, the competition for free application ranking is also extremely fierce. The daily downloads of top free (iPhone) in the United States are more than 100000, the daily downloads of iPad are more than 20000, the daily downloads of top free (iPhone) in China are 50000, and the daily downloads of iPad are more than 20000 (yes, the number of iPad in China is the same as that in the United States). Therefore, although it is a free proct, it sometimes needs to spend advertising expenses to achieve large-scale downloads, In order to push the proct to a better position. Moreover, the competition in the free list is not only the free version, but also the limited time free version of charging procts
some developers don't understand why they want to charge for free? They think it will rece potential users. In fact, there is no need to worry about this. Even if the number one downloads more than 100000 a day, it is just a drop in the bucket for Apple's huge user base. Basically, if the charged procts are free and can enter the front position of top free, they will get good results when they turn back to charging. Almost every week, we can see some procts in this way to get back to the charging list. What should be noted here is that the free time must not be short. If you change it back in a hurry within a few hours, it will have no effect at all. As long as the proct continues to climb up the list, don't stop. The more people see and download your proct, the better the effect of word-of-mouth communication will be. Of course, it can't be free without limit, Basically, three days to a week is the right time. After modifying the price, there will be a lot of news about the price change on the website, because it is known by many users, which also spawns some companies specializing in related promotion. In China, iapps.im and ewtang.com are doing better. If you want to hit the free list in China, you can contact them
back to the free version, if the free version occupies the free list for a long time, it can basically ensure that the paid version occupies the free list for a long time, which is the healthiest survival mode in the app store. However, even when the proct is released, the free version enters the list. If you want to keep it in the list for a long time, you sometimes need to buy advertisements. At present, there are many companies providing this kind of service, including Apple's own IAD, and the more famous one is AdMob. The services they provide are calculated according to how much a user clicks, and converted to download. An effective free version download may cost one dollar or more. This requires developers to decide whether to advertise after considering the ARPU of their procts. There is a misunderstanding in this. The main purpose of advertising is not to earn back the advertising expenses immediately, but to push the proct to a better position in the ranking list, so that the download can enter a virtuous circle and get more exposure. If the proct is pushed to a high level, once the advertising stops falling rapidly, it means that there are still some problems in the proct itself. It is up to the developers to decide whether to continue to promote the proct after modification or simply give up the new proct development. It should be emphasized that sometimes procts are well made, but the so-called "superficial skills" of icons, names, screenshots and descriptions are not in place, which will also affect users' desire to download. After all, many users download impulsively. If the above parts are flawed, users may choose other procts on the premise of a very large selection, This situation is not uncommon, so developers must pay attention to it
another effective way is the mutual promotion of series procts. Skynet's Zombie crisis series has proced a trilogy. In April, it successfully pushed the generation into the top paid 100 through the free introction. This way can also be used in the same type of procts, such as the chop chop Series in the United States. One of them is often free to promote other works, and the effect is not bad. The reason for the success of this method is very simple. If users get one of the procts for free and think it's good, they will naturally think that another proct of the same series or type will be excellent, so they have the willingness to pay
the competition of free list is more or less regular, and the competition of fee list is more difficult to rely on the advertising mode alone. As mentioned above, the cost of a free download may be more than one dollar, but with the same advertising resources, the cost of a fee version download may be more than ten times higher, so relatively speaking, the promotion of free version will be more effective.

9. I think it can be passed

10. When an app is submitted to the app store, if you want to pass Apple's audit, you need to work hard in many aspects, such as audit rules

first of all, we must be clear about the content of the app store audit guide, and always pay attention to Apple's updates

in September 2016, apple updated the app store audit guide again. According to aso100's translation and relevant summary of the audit guide, there are the following points to pay attention to:

before submitting the app

make sure that you have:
tested your app to ensure that it will not crash and bugs
ensure that all information and metadata of the application are complete and accurate
update the contact information to ensure the audit team can contact you in time
provide effective test account and login information, as well as hardware and resources (e.g., QR code) required for testing applications
ensure the normal operation of the background ring the audit period
if some of the application's functions and in app purchases are deeply hidden, detailed description documents and supporting documents need to be provided in the audit notes. If we are unable to use some functions of the application e to geographical or other restrictions, please provide a video link describing the function
check whether your application conforms to other guidance documents, such as development guide, design guide, brand marketing guide, etc< When users install applications from the app store, they need to confirm that this behavior is safe. Therefore, the application can not contain annoying or offensive content, and the use process will not cause physical and mental harm. We list the common pitfalls in the collection. If your app is ready to scare or offend users, the app store will not be where your app should go

1.1 inappropriate content: applications should not include offensive, sensitive, unpleasant, insulting or tasteless content
1.2 social networking and applications containing user generated information must include the following functions:
filtering bad content from published applications
providing reporting and feedback channels
providing services to prevent harassment of users
providing contact information, Let users contact you quickly
if the main purpose of using user generated content or providing services is to publish pornographic content, human flesh search, insult users, intimidate users, etc., then this kind of application should not be placed in the app store, and Apple may take it off the shelves directly without notifying the developer. If your application uses user generated information to provide network services, and the web page contains some restricted content, it needs to be hidden by default and provide an obvious nsfw (not suitable for the workplace) logo, and the user will click to display it

1.3 the application of children's classification can not include links to other applications, paid entrances and other unsuitable contents that may attract children, unless it provides the function of parent monitoring and opening; It is not allowed to include advertisements based on user behavior (that is, such advertisements will decide what content to display according to user behavior); Special attention needs to be paid to the relevant laws and regulations around the world concerning the online collection of children's data

1.4 if your application may endanger personal safety, we may reject it

1.5 make sure that the links you provide contain a very convenient way for users to find you< 2. Performance

2.1 application integrity

2.2 beta test should not be put on the app store, please use testflight instead

2.3 accuracy of application content: please ensure that your application description, screenshot and preview video are always the latest version, and can accurately reflect your application

2.3.1 don't include any hidden functions or functions without relevant documents in your application

2.3.2 if your app includes in app payment function, please make sure that the description, screenshot and preview video of your app can clearly indicate which functions, levels, subscription content, etc. need to be purchased additionally

2.3.3 screenshots must be consistent with the actual content of your application, not the title art, landing interface and flash screen interface

2.3.4 the preview video must be captured from the running effect of the application itself

2.3.5 you need to follow the category definition of the app store and choose the most appropriate category for your app

2.3.6 you have to answer the questions about age classification provided by iTunes connect honestly, so that your app can use the parental control function well

2.3.7 choose a unique app name and make sure that the keywords set can accurately describe your app. Please do not try to tease the system with any trademark terms, popular app names or other irrelevant words. The application name must be limited to 50 characters and cannot contain any terms or descriptions that have nothing to do with the application name. Apple may modify these inappropriate keywords at any time

2.3.8 your application content should be suitable for all users, so make sure that your application icon, screenshot and preview video can accurately reflect your application

2.3.9 the developer has the responsibility to guarantee the right, including the right of application icon, screenshot and preview video. Icons, screenshots and preview videos need to use information from a fictitious account rather than a real user

2.3.10 make sure your app focuses on IOS, MAC, Apple TV or apple watch, and does not include the name, icon or image of other platforms in the app or metadata, unless there are specific and recognized interactive functions

2.4 ensure hardware compatibility

2.5 software related requirements

3. Business

3.1 payment

3.1.1 in app payment:

if you want to pay, you can unlock some functions of your application (for example, subscribe content, game currency, game level, get high-quality content, unlock the full version), You have to use in app payment (IAP). The application is not allowed to include buttons, links or other calling methods and behavior guidance, and users are not allowed to pay in the way of IAP

in game virtual currency or points purchased through IAP can only be consumed in this app and cannot be expired. You should ensure that your app has the function and mechanism to recover the purchase status of in app payment for recoverable in app payment
if your in app payment type is incorrect, your app will be rejected

apps can not directly or indirectly use in app paid content and functions to give gifts to other users

apps released in the MAC app store need to use other mechanisms or include a plug-in instead of the app store itself to complete such a gift function

3.1.2 subscription: in the app store, any type of application can provide automatically updated in app paid subscription. When you incorporate auto update subscriptions into your application, be sure to follow the guidelines

3.1.3 content based "reading" application: the application allows users to access the content they have purchased or subscribed to (such as newspapers, magazines, books, audio, music, video, professional databases, Internet telephony, cloud storage and other approved services, such as ecational applications for managing student grades and curriculum). Application providers are not allowed to direct users to pay through payment mechanisms other than IAP

3.1.4 Code: applications are not allowed to use their own mechanisms to unlock application content and functions. Including license key, augmented reality logo, QR code, etc. If conditions do not allow (for example, this function can only be used with specific hardware, for example, the astronomical application can expand its function when it has a telescope), these applications can unlock these functions without using in app payment. If the function of the application is used with an approved hardware (such as a toy), only the basic function can be unlocked, and an in app value-added function can be provided. You are not allowed to ask users to buy an unrelated proct or participate in a marketing campaign to unlock the application's functions

3.1.5 goods and services outside the app: if your app allows people to buy goods and services, but the consumption of these goods and services has nothing to do with the app, you must use a non IAP method to complete the payment. For example, apple pay, credit card and debit card payment portal. The application can use the approved virtual currency for transactions (such as bitcoin, dogcoin), as long as these payment methods comply with the relevant laws and regulations of the country and region where the application is published

3.1.6 Apple pay: applications using apple pay must provide information about all goods and services to users before selling goods or services. The brand and user interface elements of Apple pay must be used correctly, and comply with the apple pay identity guidelines and human interface guidelines. When using apple pay to provide regular payment, you must provide the following information:
the length of the regular payment and clearly indicate what functions and services the regular payment will continue until it is cancelled
the actual charge bill
the way to cancel the regular payment

3.2 other business model problems

the following list is not comprehensive, Moreover, the application to be submitted may violate our latest policy. But it also provides some additional content that you should and shouldn't do:

3.2.1 acceptable way

(I) your application can be displayed to other applications you develop, but your application can't just provide directory application of other applications
(II) show or suggest a collection of other third-party applications that are designed to work in specific areas (such as health management, airline services, transportation services). Your application needs to provide powerful editing capabilities to make it look like a separate store page
(III) when the lease expires, users are prohibited from accessing specific content (such as movies, TV programs, music and books) that need to be approved for lease. But other goods and services cannot be expired
(IV) payment licenses can be used to pay or charge, transfer coupons and bills (such as movie tickets, coupons and VIP vouchers). Other uses may cause the app to be rejected or the payment license to be revoked
(V) insurance applications must be free of charge, comply with the relevant laws and regulations of the publishing area, and cannot use in app payment

3.2.2 unacceptable way

(I) display the interface, extension and plug-in of the third-party application, which looks like app store, or as a general interest collection
(II) Apple's hardware and built-in system functions need to be improved
