# Solves vs TinyMath Simple Calculator

The clearest difference is rating: Solves at 4.9 against TinyMath Simple Calculator's 4.2. Solves also leads on update cadence (every 3 weeks vs every 8 months) and ratings volume (383 vs 12). TinyMath Simple Calculator's advantage is monetization model (free vs free with in-app purchases) and review sentiment (100% vs 91%). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Solves sells 6 one-off in-app purchases and TinyMath Simple Calculator sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Solves holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: Solves has 383 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 91% of Solves's written reviews are positive against 100% of TinyMath Simple Calculator's, so the app with the better star average is not the one people write more warmly about.

Solves ships an update every 3 weeks, TinyMath Simple Calculator every 8 months. The most recent releases landed on October 22, 2026 and October 25, 2026 respectively.
