Digest of interesting materials for a mobile developer # 356 (August 3 - 9)

In this issue, we deal with RAM and subscriptions, with security and ambitious projects, with good habits and the very best applications, how design can kill your product and much more!





From year to year, Android manufacturers are pushing the hardware side of smartphones: 108 MP, 8K video recording, 12GB of RAM ... But wait, the iPhone has only 4GB of RAM. And this does not prevent him from working at the level or even faster than his competitors! And how did Apple manage to achieve this result?Every year the requirements for in-app subscriptions in mobile applications in the App Store and Google Play change, it becomes more and more difficult to take them into account the first time and not receive a series of rejections, thereby postponing the release sometimes for several months. If there are already a lot of publications about the requirements for the App Store, then sometimes questions arise with the rules of in-app subscriptions for Google Play.
