# AstroFocus vs Kaizen

The clearest difference is update cadence: Kaizen at every 2 weeks against AstroFocus's monthly. Kaizen also leads on iOS requirement (16.4 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AstroFocus sells 1 in-app purchase, starting at $3.99 per month and Kaizen sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

AstroFocus ships an update monthly, Kaizen every 2 weeks. Both last shipped on October 28, 2026.
