Verdict
The clearest difference is rating: ViCare at 4.5 against OOONO's 2.0. ViCare also leads on ratings volume (1.3K vs 1) and update cadence (every 9 days vs every 3 weeks). OOONO's advantage is in-app purchases (none vs 2) and review sentiment (56% vs 41%). On price, ads 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. ViCare sells 2 in-app purchases, starting at $3.99 per month. OOONO asks for nothing beyond the download.
ViCare holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: ViCare has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 41% of ViCare's written reviews are positive against 56% of OOONO's, so the app with the better star average is not the one people write more warmly about.
ViCare ships an update every 9 days, OOONO every 3 weeks. The most recent releases landed on September 23, 2026 and September 24, 2026 respectively.
