# Launch vs ATC

The clearest difference is update cadence: ATC at every 4 days against Launch's every 5 months. Launch's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 18.6). On price, ads and in-app purchases there is nothing between them.

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

Launch ships an update every 5 months, ATC every 4 days. The most recent releases landed on October 30, 2026 and November 9, 2026 respectively.
