I have been using Skitter happily on my iphone. The app is generally quite good (although the offline features are less than perfect). However I recently bought an android phone.
There are no example sentences in the android app. This is a really useful feature of the app on iphone
There are no uploaded mnemonics . On the IOS app there are automatic mnemonics, which you can edit if you want to improve them. Very helpful. Now I have to think of all my own, very arduous.
On the android version there a much fewer settings, the app is way less strict, which i dislike. And I cannot adjust my retention rate aims.
It is a completely different app on android, and not a better one
