# PC vs D.C.A

The clearest difference is update cadence: D.C.A at every 3 weeks against PC's every 7 months. D.C.A also leads on device support (3 vs 1) and iOS requirement (12.0 vs 15). 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.

PC ships an update every 7 months, D.C.A every 3 weeks. Both last shipped on October 26, 2026.
