# GlucoseWatch vs GotCGM

The clearest difference is price: GotCGM at Free against GlucoseWatch's $3.99. GotCGM also leads on rating (3.4 vs 2.5) and ratings volume (15 vs 2). GlucoseWatch's advantage is in-app purchases (none vs 2) and review sentiment (53% vs 30%). On update cadence, ads, device support and iOS requirement there is nothing between them.

GotCGM is free to download; GlucoseWatch costs $3.99 up front. GotCGM sells 2 in-app purchases, starting at $3.00 per month. GlucoseWatch asks for nothing beyond the download.

GotCGM holds the better App Store score, 3.4 against 2.5. That said, the two scores are not equally well evidenced: GotCGM has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 53% of GlucoseWatch's written reviews are positive against 30% of GotCGM's, so the app with the better star average is not the one people write more warmly about.

GlucoseWatch ships an update every 2 weeks, GotCGM every 3 weeks. The most recent releases landed on October 21, 2026 and October 8, 2026 respectively.
