# FastMath vs ClarifyIt

The clearest difference is rating: ClarifyIt at 5.0 against FastMath's 4.2. ClarifyIt also leads on ads (none vs shown) and iOS requirement (14.0 vs 18.6). FastMath's advantage is update cadence (every 5 days vs monthly) and ratings volume (51K vs 1). 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 ClarifyIt sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

ClarifyIt 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, ClarifyIt monthly. The most recent releases landed on October 21, 2026 and October 12, 2026 respectively.
