# Calcbot 2 vs Solves

The clearest difference is review sentiment: Solves at 91% against Calcbot 2's 60%. Solves also leads on rating (4.9 vs 4.7) and update cadence (every 3 weeks vs every 2 months). Calcbot 2's advantage is ratings volume (11K vs 381). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Calcbot 2 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.

Solves holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Calcbot 2 has 11K ratings behind it against 381, so its average is the more settled of the two. Written reviews point the same way: 60% of Calcbot 2's written reviews are positive against 91% of Solves's.

Calcbot 2 ships an update every 2 months, Solves every 3 weeks. The most recent releases landed on September 30, 2026 and September 28, 2026 respectively.
