# Mobius vs Tommoo

The clearest difference is update cadence: Tommoo at every 10 days against Mobius's every 2 months. Tommoo also leads on iOS requirement (12.0 vs 15.6). Mobius's advantage is review sentiment (27% vs 12%) and ratings volume (328 vs 31). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 2.0 for Mobius against 1.9 for Tommoo. That said, the two scores are not equally well evidenced: Mobius has 328 ratings behind it against 31, so its average is the more settled of the two. Written reviews are what separate them: 27% of Mobius's written reviews are positive against 12% of Tommoo's.

Mobius ships an update every 2 months, Tommoo every 10 days. The most recent releases landed on September 26, 2026 and September 20, 2026 respectively.
