Verdict
The clearest difference is review sentiment: Bluclock at 100% against UVmeter's 43%. Bluclock also leads on in-app purchases (none vs 2) and ads (none vs shown). UVmeter's advantage is update cadence (every 3 weeks vs every 56 months) and ratings volume (82 vs 1). On price 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
Both are free to download. UVmeter sells 2 one-off in-app purchases. Bluclock asks for nothing beyond the download.
UVmeter holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: UVmeter has 82 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of UVmeter's written reviews are positive against 100% of Bluclock's, so the app with the better star average is not the one people write more warmly about.
UVmeter ships an update every 3 weeks, Bluclock every 56 months. The most recent releases landed on October 16, 2026 and October 7, 2026 respectively.
