# Osmo Lettertopia vs XMAKER HD

The clearest difference is rating: Osmo Lettertopia at 3.3 against XMAKER HD's 2.5. Osmo Lettertopia also leads on device support (3 vs 1) and ratings volume (75 vs 20). XMAKER HD's advantage is monetization model (free vs free with in-app purchases) and review sentiment (21% vs 6%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Osmo Lettertopia sells 2 one-off in-app purchases and XMAKER HD sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Osmo Lettertopia holds the better App Store score, 3.3 against 2.5. Both are backed by a comparable volume of ratings — 75 and 20 respectively. Written reviews complicate that: 6% of Osmo Lettertopia's written reviews are positive against 21% of XMAKER HD's, so the app with the better star average is not the one people write more warmly about.

Osmo Lettertopia ships an update every 3 months, XMAKER HD every 2 months. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
