# Calculator· vs Solves

The clearest difference is ads: Solves at none against Calculator·'s shown. Solves also leads on update cadence (every 3 weeks vs every 2 months). Calculator·'s advantage is ratings volume (34K vs 381) and iOS requirement (12.0 vs 15). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Calculator· sells 3 in-app purchases, starting at $0.99 per month 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 — 4.9 for Calculator· against 4.9 for Solves. That said, the two scores are not equally well evidenced: Calculator· has 34K ratings behind it against 381, so its average is the more settled of the two. Written reviews are what separate them: 84% of Calculator·'s written reviews are positive against 91% of Solves's.

Calculator· ships an update every 2 months, Solves every 3 weeks. The most recent releases landed on September 24, 2026 and September 19, 2026 respectively.
