With Checker-wise you can play international 10x10 checkers. Its most unique feature is an interface to the database of the games of the Dutch national checkers competition. A lot of attention has been paid to the graphics, with the aim to make it look beautiful, without any distracting bling-bling. All moves are animated. You can choose from 2 different sets of pieces. Checker-wise has VoiceOver integration, making it the only mobile checkers application which is fully accessible to blind users. PLAY Games can be either for 1 or 2 players, and either with or without a clock. Of course, all the standard features like swapping sides or rotating the board are available. The engine contains a strong opening book. ANALYZE Checker-wise contains a separate screen for analyzing positions. You can try out side variations and return to the main line with a simple double tap on the corresponding move in the move list. You can ask the engine for an evaluation. SETUP You can setup a position using an intuitive interface. REPLAY Look through the game you just played, and email the game notation, or copy it to the clipboard. TOURNAMENT BASE Checker-wise contains an interface to all of the games of the Dutch national checker competition. You can not only play through the games of the masters, but also analyse their games with the onboard engine, or take over the play from any position. And new games are added every week! EXERCISES Finally, there is a large collection of exercises which keeps track of which ones you've solved. Each of these features alone is worth the price of Checker-wise! And regular updates expand the possibilities of Checker-wise even more. Checker-wise is based on the Tjes engine (developed by me in 1996). Enjoy!

Verdict
The clearest difference is price: Drop4 at Free against Checker's $0.99. Checker's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.1). On in-app purchases and device support there is nothing between them.
