I lost a lot of games on the iPad because of:
- miss click
- miss swap
- microfreeze + miss click / miss swap
In fact ipad client is not suitable for rating games because of control. ipad control needs serious reworking (like disabling swap, click confirmation, etc.)
Also i think you can add 30 seconds to the move on ipad because of control difficulties. (It’s really difficult to very carefully control the sencor clicks and pondering a complex part at the same time)
