# PROG vs Scan Flow

The clearest difference is update cadence: PROG at every 3 days against Scan Flow's fortnightly. PROG also leads on iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PROG sells 4 in-app purchases, starting at $9.99 per month and Scan Flow sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PROG ships an update every 3 days, Scan Flow fortnightly. The most recent releases landed on October 31, 2026 and October 28, 2026 respectively.
