# Quantum vs Excel Classes

The clearest difference is update cadence: Quantum at every 5 weeks against Excel Classes's every 6 months. Excel Classes's advantage is iOS requirement (15.5 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Quantum sells 3 one-off in-app purchases and Excel Classes sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Quantum ships an update every 5 weeks, Excel Classes every 6 months. Both last shipped on October 11, 2026.
