Normally a tablebase of this size takes up 7 GB of space, but this app sends the position to a
remote server and returns the result - so it does not take up space on your smartphone or tablet!

So get the tool you need to check your endgame positions with 100 % accuracy.

Some 6 piece endgames are also supported.
More are planned if enough users support this app by buying it.
