# Quantum vs Henge

The clearest difference is update cadence: Henge at every 10 days against Quantum's every 5 weeks. Henge also leads on iOS requirement (17.0 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 Henge sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Quantum ships an update every 5 weeks, Henge every 10 days. The most recent releases landed on October 24, 2026 and October 18, 2026 respectively.
