# Pre vs Trigonometry for Beginners

The clearest difference is rating: Trigonometry for Beginners at 4.7 against Pre's 3.3. Trigonometry for Beginners also leads on ratings volume (10 vs 3). Pre's advantage is ads (none vs shown) and iOS requirement (8.0 vs 17.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Pre 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 3.3. Both are backed by a comparable volume of ratings — 3 and 10 respectively.
