Unfortunately, there is no such function as text messages recognition in CoinKeeper for iOS devices yet. The Apple company is strict concerning management of users' personal data. For this reason, it's not possible to realize function of text message recognition the same way we do it in the Android-based version of the application at the moment.
We are in search of possible ways of realization of SMS recognition for iOS-based version of the application. Unfortunately, there are many difficulties, but we hope that sooner or later such option will appear.
For this reason, we considered it’s fair not to include the option of SMS recognition in paid functionality of the Premium subscription neither for Android, nor for iOS version of the app. Function is absolutely free. That means, if you try the free version of CoinKeeper application on Android, you will see in the side Menu unlocked option “Bank SMS”.
