#10 edit: Only the application with the name "chess" has puzzles IIRC. There are 500 of them, they are pretty tough and very well designed. The name of the puzzle collection is "el arte del mate en dos" (mate in two) If you happen to have solved them all, you can import further ones, available from a website with the same name.
thanks Turais!
All puzzles in iChess are offline! (except when you wish to purchase something from the Store, which has more puzzles based on Openings, from Recent 2015 games, Mates etc)

I now checked the following ones and like all of them:
-iChess https://play.google.com/store/apps/details?id=com.pereira.ichess&referrer=utm_source%3Dap%26utm_medium%3Dli
-Chess Tactics Pro https://play.google.com/store/apps/details?id=net.lrstudios.android.chess_problems
-Chess Tactic Puzzles https://play.google.com/store/apps/details?id=com.timleg.chesstactics
They all work offline, which was most important for me.
#13, Neat work, glad u noticed the thread and let us know. Can you add a way to later evaluate how user is developing in terms of the time it takes for him/her to find the solutions ?
