# BIOValid vs Greenn

The clearest difference is review sentiment: Greenn at 72% against BIOValid's 25%. Greenn also leads on update cadence (every 6 days vs every 3 months). BIOValid's advantage is rating (4.6 vs 1.0) and ratings volume (34 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

BIOValid holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: BIOValid has 34 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 25% of BIOValid's written reviews are positive against 72% of Greenn's, so the app with the better star average is not the one people write more warmly about.

BIOValid ships an update every 3 months, Greenn every 6 days. The most recent releases landed on October 19, 2026 and October 6, 2026 respectively.
