Monitor Glucose

Your glucose, readable from across a dark room.

Monitor Glucose shows the readings from your own Nightscout site in one big number, coloured by the zones you choose, with alarms gentle enough to wake you and not the whole house.

Made for the night shift

Whether you watch your own readings or a child's, Monitor Glucose is built around the moments you check half-awake.

  • A night view you can read without glasses

    The reading, its arrow and how old it is, large and dimmed. You choose what it shows and where.

  • Zones that follow your day

    Set your own red, yellow and green ranges for each part of the day: tighter after dinner, wider overnight, or however your care team suggests.

  • Alarms that wake you gently

    Soft music instead of sirens, with volume that stays steady, rises or falls, and snooze buttons you set to the minutes you actually use.

  • Says why when something is late

    If readings or loops stop arriving, the top line tells you the likely cause, such as no internet or the CGM connection being down, instead of just going quiet.

  • Loop, Trio and AndroidAPS aware

    See insulin and carbs on board, the current basal, the last loop and its prediction line next to your readings.

  • Reports to share

    Time in range, daily patterns and totals, saved as a PDF on your phone to bring to your next appointment.

What you need

Monitor Glucose shows data. It doesn't read a sensor itself.

  • A continuous glucose monitor (CGM) whose readings already reach a Nightscout site, or another Nightscout-compatible server.
  • That site's address and an access token with read permission. An API secret also works if you want to log treatments.
  • An iPhone, an Android phone or tablet (Android 7 or newer), or any web browser.

Monitor Glucose Plus

Plus is the same app with Loop remote commands: carbs, boluses and overrides sent to the Loop phone you follow. Like Loop itself, you build it yourself from GitHub with your own Apple or Google developer account. Build instructions will be published here.

Monitor Glucose is not a medical device. It does not diagnose, treat, cure or prevent any condition. Readings can be late or missing when a sensor, phone, internet connection or server has a problem. Always confirm with your meter or CGM before making a treatment decision, and talk to your healthcare team about your targets.
