Verdict
The clearest difference is update cadence: Batteries at every 2 days against OnClock's every 3 weeks. Batteries also leads on rating (2.9 vs 2.5) and ratings volume (10 vs 2). OnClock's advantage is review sentiment (63% vs 38%) and price ($0.99 vs $3.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
OnClock costs $0.99 and Batteries $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Batteries holds the better App Store score, 2.9 against 2.5. That said, the two scores are not equally well evidenced: Batteries has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 63% of OnClock's written reviews are positive against 38% of Batteries's, so the app with the better star average is not the one people write more warmly about.
OnClock ships an update every 3 weeks, Batteries every 2 days. The most recent releases landed on November 4, 2026 and November 3, 2026 respectively.
