# Zero Substrate vs 毎日ミステリー

The clearest difference is device support: 毎日ミステリー at 3 against Zero Substrate's 1. 毎日ミステリー also leads on iOS requirement (15.0 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Zero Substrate sells 1 one-off in-app purchase and 毎日ミステリー sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
