# Flex vs HealHabit

The clearest difference is ads: HealHabit at none against Flex's shown. HealHabit also leads on update cadence (every 3 days vs every 10 days). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Flex sells 3 in-app purchases, starting at $4.99 per month and HealHabit sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Flex ships an update every 10 days, HealHabit every 3 days. The most recent releases landed on October 24, 2026 and October 9, 2026 respectively.
