@ software updates - it automatically detects the update is ready, notifies you when you start it up - and updates. Takes about 1 minute
@ Lessons - lessons are in the app (as an audio source). This is not fully released. It has been in the works for years and is about to launch. We have a beta on iOS but it only works with ChessUp 1. Full android and iOS release and ChessUp 2 support is in one of these upcoming updates.
@ Checkers - 1.1.0 will have checkers - it should be a couple of weeks.
