Verdict
The clearest difference is rating: Letsfit at 4.2 against ViLive's 2.8. Letsfit also leads on ratings volume (6.3K vs 272) and update cadence (every 5 weeks vs every 3 months). ViLive's advantage is review sentiment (41% vs 25%) and iOS requirement (10.0 vs 12.0). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
Letsfit holds the better App Store score, 4.2 against 2.8. That said, the two scores are not equally well evidenced: Letsfit has 6.3K ratings behind it against 272, so its average is the more settled of the two. Written reviews complicate that: 41% of ViLive's written reviews are positive against 25% of Letsfit's, so the app with the better star average is not the one people write more warmly about.
ViLive ships an update every 3 months, Letsfit every 5 weeks. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
