# To vs MUST

The clearest difference is update cadence: MUST at every 4 days against To's every 3 weeks. MUST also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. To sells 1 one-off in-app purchase and MUST sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

To ships an update every 3 weeks, MUST every 4 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
