# GMT Time vs HitoMemo

The clearest difference is in-app purchases: HitoMemo at none against GMT Time's 1. HitoMemo also leads on ads (none vs shown) and iOS requirement (11.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. GMT Time sells 1 one-off in-app purchase. HitoMemo asks for nothing beyond the download.
