# FastMath vs Truncated Cone

The clearest difference is rating: Truncated Cone at 5.0 against FastMath's 4.2. Truncated Cone also leads on ads (none vs shown) and iOS requirement (15.0 vs 18.6). FastMath's advantage is ratings volume (51K vs 1) and update cadence (every 5 days vs every 3 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. FastMath sells 5 in-app purchases, starting at $4.99 per 7 days and Truncated Cone sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Truncated Cone holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: FastMath has 51K ratings behind it against 1, so its average is the more settled of the two.

FastMath ships an update every 5 days, Truncated Cone every 3 weeks. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
