# Dosatron vs TM+ Pro

The clearest difference is rating: Dosatron at 3.5 against TM+ Pro's 3.1. TM+ Pro's advantage is review sentiment (32% vs 17%) and ratings volume (97 vs 17). On price, update cadence, 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.

Dosatron holds the better App Store score, 3.5 against 3.1. That said, the two scores are not equally well evidenced: TM+ Pro has 97 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 17% of Dosatron's written reviews are positive against 32% of TM+ Pro's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on June 1, 2026 and September 22, 2026 respectively.
