About this app

Monitor your Nightscout glucose levels on your Android phone or tablet. Dark UI, large readings and buttons, designed for usage at night.

The app does not use any device sensors or external hardware to read glucose levels, but it does require you to set up a Nightscout server. Read more here: https://nightscout.github.io.

Use Nightwatch (this app) for Android completely at your own risk, do not use the information in the app to make medical decisions. The developers of this app cannot be held accountable for any malfunction in the app as it depends on third party services and devices connected to third party services to function correctly. This app is not affiliated with Dexcom or any other glucose monitoring system.

I use this to track my young son's BGL, either on an old tablet hanging on the wall or on my phone. After the latest update, the screen now times put on my phone which is a bit annoying.

Please kill and restart the app and it should go back the old UI. I am working on a fix for this.

Says my Nightscout 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.

I use this app as a display on a fire tablet at night time for alarms and works well most of the time. But few things annoying me, it alarms when tablet loses wifi and alarms when calibration added to daughters phone. Neither are options to configure in settings. A graph would be awesome also too to show trend so i know instantly if its a fast or slow bg fall.
