# Flutter vs Fold

The clearest difference is update cadence: Fold at every 3 days against Flutter's every 8 days. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Flutter sells 10 one-off in-app purchases and Fold sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Flutter ships an update every 8 days, Fold every 3 days. The most recent releases landed on November 12, 2026 and October 31, 2026 respectively.
