# iHour vs Calflow

The clearest difference is update cadence: Calflow at every 10 days against iHour's every 6 weeks. iHour's advantage is ratings volume (816 vs 131) and iOS requirement (13.0 vs 17.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. iHour sells 6 in-app purchases, starting at $0.49 per month and Calflow sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for iHour against 4.9 for Calflow. That said, the two scores are not equally well evidenced: iHour has 816 ratings behind it against 131, so its average is the more settled of the two. Written reviews are what separate them: 90% of iHour's written reviews are positive against 89% of Calflow's.

iHour ships an update every 6 weeks, Calflow every 10 days. The most recent releases landed on October 26, 2026 and October 27, 2026 respectively.
