# Kaizen vs DisabilityLog

The clearest difference is update cadence: Kaizen at every 2 weeks against DisabilityLog's every 3 months. Kaizen also leads on iOS requirement (15.6 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Kaizen sells 7 in-app purchases, starting at $3.99 per month and DisabilityLog sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Kaizen ships an update every 2 weeks, DisabilityLog every 3 months. The most recent releases landed on October 30, 2026 and November 5, 2026 respectively.
