# Calculator⁼ vs Solves

The clearest difference is review sentiment: Solves at 91% against Calculator⁼'s 36%. Solves also leads on ads (none vs shown) and rating (4.9 vs 4.6). Calculator⁼'s advantage is ratings volume (358K vs 381). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calculator⁼ sells 8 in-app purchases, starting at $0.49 per 7 days and Solves sells 6 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 4.6. That said, the two scores are not equally well evidenced: Calculator⁼ has 358K ratings behind it against 381, so its average is the more settled of the two. Written reviews point the same way: 36% of Calculator⁼'s written reviews are positive against 91% of Solves's.

Calculator⁼ ships an update monthly, Solves every 3 weeks. The most recent releases landed on September 25, 2026 and September 19, 2026 respectively.
