# OnClock vs 씽크에어 PRO

The clearest difference is price: 씽크에어 PRO at Free against OnClock's $0.99. 씽크에어 PRO also leads on rating (5.0 vs 2.5) and iOS requirement (10.0 vs 14.0). OnClock's advantage is review sentiment (63% vs 25%) and update cadence (every 3 weeks vs every 3 months). On ratings volume, ads, in-app purchases and device support there is nothing between them.

씽크에어 PRO is free to download; OnClock costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

씽크에어 PRO holds the better App Store score, 5.0 against 2.5. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 63% of OnClock's written reviews are positive against 25% of 씽크에어 PRO'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, 씽크에어 PRO every 3 months. The most recent releases landed on October 3, 2026 and October 7, 2026 respectively.
