It works like a champ as long as the app is open and your setup is good. I have asked for a port to the Edge 520.

Love that this app is available for Garmin devices. We have been Nightscouters for 2 years and love it for monitoring our 9-year old son's T1D. As I am an active MTB and cycling coach, I went through a few Pebbles, and found they just couldn't handle my activity level. Love that I can now use this on my Fenix 3!

Hello Thanks for a great app!! Is it possible in the future to have a app like this but for 2 users? Both my kids have diabetes and I can only follow one of them in this app

Fantastic app. Wasn't sure about sharing my API at first so if there is another way of connecting without API disclosure that would be good. My only gripe is that when notifications come through my Garmin Fenix 3 beeps even though it is set to vibrate only. It only beeps when this app is running. Being able to totem off those beeps would mean 5 stars

The app for me is great. Andreas-may would you be sooooo kind to develop a new app where we can find the blood glucose and the heart rate at the same time? When I go running for me it's very importante to check both blood glucose, heart rate (and time also would be perfect). Thankssss

The screen of CGM Watch is simple: • Minutes since last glucose reading • Last glucose reading • Glucose trend arrow • Colored glucose control status bar • Time • Battery graphic • Date and battery % Touch or tap anywhere and the backlight turns on--Love this. At night I hear CGM alarms sometimes go back to sleep in frustration. Forget having to find your Dexcom receiver on the floor after knocking it off the night stand. Tap the watch face instead, done! Touch and hold your finger on the face to see the stock digital watch face and widgets. You must do this to see step count. CGM Watch It is actually running as an application instead of a replacement for the stock digital watch face. You must exit CGM Watch like ending a fitness activity to see a Connect IQ widget. Not a deal breaker for me. I did have Nightscout Widget by Phimby installed, but I uninstalled. The graph was a nice idea, but so slow I didn't use it much. The CGM number was good, but you had to swish side to side to see it. If you have another watch face you that you really really like, maybe you would keep Phimby's widget and skip CGM Watch. You still get every kind of notification coming in that you have set up on your phone. I do get a lot of them, and I use my GPS a lot for fitness, so that means I recharge my watch battery daily. I can't tell you if CGM Watch is a big battery drain or not. At first I was nervous about pasting in my MongoLab API key in CGM Watch settings. Now I am okay with it. The whole spirit of Nightscout is people helping people affected by T1D. I can't imagine anything malicious done in the name of Nightscout. Besides, you can get a new API key anytime you want to shut down someone's access. I depend on my technology to manage T1D more than most people. I have results to show for it: 25 years T1D, no complications, A1C 6.5 to 7.0 since 2012 (always 7-8 before), lost 50 lbs since 2014. Thank you Andreas-May and Phimby too!
