# Withings vs Opthy

The clearest difference is in-app purchases: Opthy at none against Withings's 3. Opthy also leads on iOS requirement (14.0 vs 18.0). Withings's advantage is ratings volume (367K vs 2.9K) and update cadence (fortnightly vs monthly). On price, rating, ads and device support there is nothing between them.

Both are free to download. Withings sells 3 in-app purchases, starting at $9.99 per month. Opthy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for Withings against 4.5 for Opthy. That said, the two scores are not equally well evidenced: Withings has 367K ratings behind it against 2.9K, so its average is the more settled of the two. Written reviews are what separate them: 25% of Withings's written reviews are positive against 13% of Opthy's.

Withings ships an update fortnightly, Opthy monthly. The most recent releases landed on October 16, 2026 and October 15, 2026 respectively.
