# API vs GRAAS

The clearest difference is update cadence: API at every 6 days against GRAAS's every 3 weeks. API also leads on iOS requirement (13.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

API ships an update every 6 days, GRAAS every 3 weeks. The most recent releases landed on June 7, 2026 and September 5, 2026 respectively.
