# Quick Graph vs Logarithm Solver

The clearest difference is rating: Logarithm Solver at 5.0 against Quick Graph's 4.6. Logarithm Solver also leads on update cadence (every 3 weeks vs every 3 months). Quick Graph's advantage is ratings volume (405 vs 1) and iOS requirement (9.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quick Graph sells 1 one-off in-app purchase and Logarithm Solver sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Logarithm Solver holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Quick Graph has 405 ratings behind it against 1, so its average is the more settled of the two.

Quick Graph ships an update every 3 months, Logarithm Solver every 3 weeks. The most recent releases landed on September 28, 2026 and August 26, 2026 respectively.
