# FastMath vs MathLens

The clearest difference is ads: MathLens at none against FastMath's shown. MathLens also leads on iOS requirement (16.6 vs 18.6). FastMath's advantage is ratings volume (51K vs 6) and rating (4.2 vs 4.0). 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 MathLens sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

FastMath holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: FastMath has 51K ratings behind it against 6, so its average is the more settled of the two.

FastMath ships an update every 5 days, MathLens every 2 weeks. The most recent releases landed on October 14, 2026 and September 30, 2026 respectively.
