# WELE vs PolyPi AI

The clearest difference is update cadence: PolyPi AI at every 3 days against WELE's every 8 days. PolyPi AI also leads on iOS requirement (12.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. WELE sells 1 in-app purchase, starting at $9.99 per year and PolyPi AI sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

WELE ships an update every 8 days, PolyPi AI every 3 days. Both last shipped on November 3, 2026.
