# iHour vs CoStudy

The clearest difference is ads: iHour at none against CoStudy's shown. iHour also leads on ratings volume (816 vs 71) and device support (4 vs 2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. iHour sells 6 in-app purchases, starting at $0.49 per month and CoStudy sells 13 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 4.8 for CoStudy. That said, the two scores are not equally well evidenced: iHour has 816 ratings behind it against 71, 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 93% of CoStudy's.

iHour ships an update every 6 weeks, CoStudy every 3 weeks. The most recent releases landed on October 20, 2026 and October 14, 2026 respectively.
