# Granula vs PO

The clearest difference is update cadence: PO at every 2 days against Granula's weekly. PO also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Granula sells 1 in-app purchase, starting at $2.99 per month and PO sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Granula ships an update weekly, PO every 2 days. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
