# Flex vs Dosette

The clearest difference is update cadence: Dosette at fortnightly against Flex's every 3 months. Flex's advantage is iOS requirement (13.4 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Flex sells 2 in-app purchases, starting at $13.99 per month and Dosette sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Flex ships an update every 3 months, Dosette fortnightly. The most recent releases landed on September 29, 2026 and October 4, 2026 respectively.
