# Amazing Calculator vs Solves

The clearest difference is update cadence: Solves at every 3 weeks against Amazing Calculator's every 51 months. Solves also leads on ratings volume (381 vs 5) and device support (5 vs 3). Amazing Calculator's advantage is monetization model (free vs free with in-app purchases) and review sentiment (100% vs 91%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Amazing Calculator sells 1 one-off in-app purchase and Solves sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Amazing Calculator against 4.9 for Solves. That said, the two scores are not equally well evidenced: Solves has 381 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 100% of Amazing Calculator's written reviews are positive against 91% of Solves's.

Amazing Calculator ships an update every 51 months, Solves every 3 weeks. The most recent releases landed on June 5, 2026 and September 19, 2026 respectively.
