# TS vs DA

The clearest difference is update cadence: DA at every 2 days against TS's every 4 months. DA also leads on device support (3 vs 1). TS's advantage is iOS requirement (9.0 vs 11.0). 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.

TS ships an update every 4 months, DA every 2 days. The most recent releases landed on October 26, 2026 and October 28, 2026 respectively.
