# Therimax vs Depmin

The clearest difference is in-app purchases: Depmin at none against Therimax's 3. Depmin also leads on review sentiment (100% vs 83%). Therimax's advantage is update cadence (every 2 months vs every 11 months) and rating (4.2 vs 4.0). On price and ads there is nothing between them.

Both are free to download. Therimax sells 3 one-off in-app purchases. Depmin asks for nothing beyond the download.

Therimax holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Therimax has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Therimax's written reviews are positive against 100% of Depmin's, so the app with the better star average is not the one people write more warmly about.

Therimax ships an update every 2 months, Depmin every 11 months. The most recent releases landed on October 23, 2026 and October 20, 2026 respectively.
