Type 1 diabetes, on every screen

From distraction to ally.

Make your iPhone and Apple Watch a tool for diabetes — not a distraction from it.

Glucose and carbs everywhere — Home Screen, Lock Screen, StandBy, every Apple Watch face. A friendly green face when things look good, a red one when something needs your attention. Other apps stay blocked until you've done the diabetes thing.

  • GluWink check-in shield with a green face: glucose and carbs at a glance.

GluWink does three things, and nothing more.

  1. Glucose and carbs visible everywhere.

    Widgets in every size for Home Screen, Lock Screen, and StandBy. Complications on every Apple Watch face. An optional glucose number on the app icon badge.

  2. Clear status at a glance.

    A green face means everything looks good. A red face means something needs attention — glucose is high or low, the sensor is stale, or carbs were never entered for that meal. Same simple language across the app, widgets, and watch.

  3. Optional app blocking — your call.

    Block other apps at configurable intervals — always, or only when something needs your attention. While blocking is on and the face is red, GluWink locks other apps until you check in. Otherwise, your phone is just your phone.

Built for two audiences.

For parents

Children with Type 1, on a Family-Sharing iPhone.

  • Set GluWink up once on the child's iPhone via Family Sharing.
  • Pick which apps stay free to use (the CGM app, school apps, phone, messages).
  • A passphrase only the parent knows protects the settings.
  • The child cannot delete the app or skip the check-in.
  • Glance at the home-screen badge or a widget to see how things are going.

For adults

Self-managing your own Type 1, on your own iPhone.

  • Authorize GluWink for yourself — no Family Sharing required.
  • Have a partner, spouse, or friend set the passphrase. The friction is the point.
  • You can always uninstall — GluWink is honest about that. It nudges, it doesn't imprison.

Where the data comes from.

GluWink reads what's already on your phone. No accounts to create. Pick whichever source fits.

Apple Health

Most CGM apps (Dexcom, Libre, CamAPS, xDrip, Loop, iAPS, and others) already write glucose and carbs to Apple Health. If yours does, GluWink is a one-tap connection.

Nightscout

Connect your own Nightscout site — handy when a parent monitors a child remotely, or when your diabetes system writes to Nightscout but not Apple Health. Both sources can be on at once; the most recent reading wins.

Demo mode

Want to try the app first? Demo mode shows realistic glucose and carb data without any sensor.

Your data stays on your device (HealthKit) or on the Nightscout site you control. No accounts, no servers we run, no analytics, no ads.

Not a medical device.

GluWink does not replace your CGM, your pump, your endocrinologist, or your judgment. It does not make treatment decisions. It surfaces information that's already on the phone and asks one question: did you do the diabetes thing yet?

Open source.

GluWink is open source under the PolyForm Noncommercial License. You can read the code, build it for your own devices, share builds with private testers, and contribute back.
