# Ezy Trigonometry vs Trigonometry calc

The clearest difference is rating: Trigonometry calc at 3.0 against Ezy Trigonometry's 2.5. Ezy Trigonometry's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Trigonometry calc sells 1 one-off in-app purchase. Ezy Trigonometry asks for nothing beyond the download.

Trigonometry calc holds the better App Store score, 3.0 against 2.5. That said, the two scores are not equally well evidenced: Ezy Trigonometry has 44 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 22% of Ezy Trigonometry's written reviews are positive against 0% of Trigonometry calc'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 3 months. The most recent releases landed on June 10, 2026 and September 6, 2026 respectively.
