# Tutorius vs Onsen SAT

The clearest difference is in-app purchases: Onsen SAT at none against Tutorius's 1. Onsen SAT also leads on rating (5.0 vs 4.8). Tutorius's advantage is ratings volume (40 vs 1) and update cadence (weekly vs fortnightly). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Tutorius sells 1 in-app purchase, starting at $9.99 per month. Onsen SAT asks for nothing beyond the download.

Onsen SAT holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Tutorius has 40 ratings behind it against 1, so its average is the more settled of the two.

Tutorius ships an update weekly, Onsen SAT fortnightly. The most recent releases landed on September 20, 2026 and June 11, 2026 respectively.
