# FastMath vs SimpleTools

The clearest difference is review sentiment: SimpleTools at 100% against FastMath's 17%. SimpleTools also leads on rating (5.0 vs 4.2) and ads (none vs shown). FastMath's advantage is ratings volume (51K vs 1) and update cadence (every 5 days vs every 4 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 SimpleTools sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SimpleTools 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. Written reviews point the same way: 17% of FastMath's written reviews are positive against 100% of SimpleTools's.

FastMath ships an update every 5 days, SimpleTools every 4 weeks. The most recent releases landed on September 30, 2026 and September 18, 2026 respectively.
