# Trigonometry! vs Trigonometry for Beginners

The clearest difference is rating: Trigonometry for Beginners at 4.7 against Trigonometry!'s 2.0. Trigonometry!'s advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Trigonometry! sells 1 one-off in-app purchase and Trigonometry for Beginners sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Trigonometry for Beginners holds the better App Store score, 4.7 against 2.0. Both are backed by a comparable volume of ratings — 4 and 10 respectively. Written reviews complicate that: 14% of Trigonometry!'s written reviews are positive against 0% of Trigonometry for Beginners's, so the app with the better star average is not the one people write more warmly about.

Trigonometry! ships an update every 4 months, Trigonometry for Beginners every 5 months. The most recent releases landed on September 18, 2026 and September 23, 2026 respectively.
