In order for this to work, you need an account in Night scout. Log in to Night scout first, with your admin account, and select Admin tools. Create a new account and set permissions to readable. Save and copy the new account name and access token to this app.

Works for its purpose of being my alarm clock with BG displayed. Unfortunately it sometimes loses connectivity for 30 seconds or so and starts an alert noise. This forces me to mute my phone if I want to use it and use a different phone for dexcom since I can't mute the phone and have my dexcom alerts play. As other haves stated. A preview on of the graph small on the screen would be great too.

Says my Night scout server URL is 'Unauthorized', but it works fine in a browser. So I'm not sure what the problem is. If there's some format that the URL needs to be in (other than what you'd expect) it would be helpful if this was specified. So I've not been able to make use of this app, but it's nice to see that it was last updated not too long ago.

Decided to start this since the Dexcom app will no longer work for my son's phone. However, all I get for my son is data that is an hour or more old, which isn't enough time to stop a high/low glucose level. Also, I cannot see anything on the web browser on my computer. Worst app ever.

I'm unimpressed,,, This is neither simple, nor easy, nor appreciated. I'm here trying to get my cgm to work with alexa... grrr
