Verdict
The clearest difference is rating: Viome at 4.6 against Arii's 4.0. Viome also leads on in-app purchases (none vs 1) and ratings volume (5.5K vs 6). Arii's advantage is update cadence (weekly vs every 6 weeks) and review sentiment (50% vs 41%). On price, ads, 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
Both are free to download. Arii sells 1 in-app purchase, starting at $4.99 per month. Viome asks for nothing beyond the download.
Viome holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Viome has 5.5K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 41% of Viome's written reviews are positive against 50% of Arii's, so the app with the better star average is not the one people write more warmly about.
Viome ships an update every 6 weeks, Arii weekly. The most recent releases landed on October 20, 2026 and October 12, 2026 respectively.
