# iHour vs Accumulate

The clearest difference is rating: iHour at 4.8 against Accumulate's 4.0. iHour also leads on ratings volume (810 vs 1). Accumulate's advantage is update cadence (every 10 days vs monthly) and review sentiment (100% vs 90%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

iHour holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: iHour has 810 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of iHour's written reviews are positive against 100% of Accumulate's, so the app with the better star average is not the one people write more warmly about.

iHour ships an update monthly, Accumulate every 10 days. The most recent releases landed on October 14, 2026 and September 30, 2026 respectively.
