# Off vs Chess Timekeeper

The clearest difference is in-app purchases: Chess Timekeeper at none against Off's 1. Chess Timekeeper also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.0). On price and device support there is nothing between them.

Both are free to download. Off sells 1 one-off in-app purchase. Chess Timekeeper asks for nothing beyond the download.
