# OneClock vs iJumper

The clearest difference is rating: iJumper at 4.5 against OneClock's 3.9. iJumper also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 3 weeks vs every 3 months). OneClock's advantage is ads (none vs shown) and iOS requirement (16.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. OneClock sells 2 in-app purchases, starting at $0.99 per month and iJumper sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

iJumper holds the better App Store score, 4.5 against 3.9. That said, the two scores are not equally well evidenced: iJumper has 177 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 83% of OneClock's written reviews are positive against 100% of iJumper's.

OneClock ships an update every 3 months, iJumper every 3 weeks. Both last shipped on October 24, 2026.
