Store review

This handy chess rating calculator app can calculate the expected score,
rating change and performance rating of your chess games.

It uses FIDEs official rating rules and includes the new 400 rating difference
rule used in the ELO rating system (most apps do not calculate correctly with
this rule) You can enter game data and the rating calculations are
automatically saved, so you do not need to re-enter them if you add further
games later on. You can save a rating list as a tournament to keep track of
your results and improvements from chess tournament to chess tournament.

There is also a graphical overview of your rating improvements from tournament
to tournament.

Finally, you can backup your rating info to the cloud and sync it across
different devices. Useful if you own both a phone and a tablet and want to
have access to the same info.

Furthermore, various k-factors are supported - also non-FIDE k-factors used by
many national chess federations, so you can use this app for local tournaments
as well.
