Nothing stands out.

★★★★★ The interface is clean and easy to use.
★★★★★ I am 1800 USCF and I love the tactics trainer included. It show refutations to errors. The whole thing is first class. I am not sure I agree it's only for low rated players. Excellent!
★★★★★ It had an UGLY interface called Peshka that required you to be constantly online to access a server of problems you own.

Great practice for beginners
These are like real game problems. You are not sure what type of advantage you might get in the situation that is presented. This gives you practice that you would get in crucial situations in a game.
Very helpful for myself as a beginner
First let me say I am about 1/3 of the way thru this app. this app has improved my game from”wood pusher” to seeing tactical situations and I expect to continue to improve. I will definitely continue to buy more advanced apps as I improve. However; first of all it needs some text explaining the procedures, charts and numbers though after a week I began to figure it out. (Admittedly I’m a senior). Second, when doing combination practices it has several sections oftypes that weren’t covered in the theory section. So it is frustrating trying to figure out why a move is marked as wrong because it doesn’t match what the A.I. Is looking for. Still I would recommend this app for beginners and early intermediates looking to improve their game.
A little hard to follow even after reading entire beginning section. There should be a brief demo of the interface and the steps required.
