Total junk and rubbish
The only pros of app is big database. The rest is not so good. Some times pieces from one riddle are left to another and this does not allow correct solution. En passant move is a totally not working as expected. Some times you get blank board. Game over caption can stay on board during solving next combination. Part of tasks are not correct, although check mate is possible in two different moves only one is correct (I checked it with help of computer). I would not buy it again.
