# KINTAI vs Work Log

The clearest difference is update cadence: KINTAI at weekly against Work Log's fortnightly. KINTAI also leads on device support (3 vs 1) and iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. KINTAI sells 9 in-app purchases, starting at $29.99 per month and Work Log sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

KINTAI ships an update weekly, Work Log fortnightly. Both last shipped on October 31, 2026.
