Your Health Data.
Your Device.
Your Control.
GlucoBeacon gives you a complete picture of your diabetes — blood sugar trends, A1C estimates, restaurant guidance, workout routines, meal history, and an AI coach — all stored privately on your phone. No cloud. No accounts. No compromise.
"I've been Type 2 for over 20 years. I tried the popular diabetes apps — for years. They were clunky, half-finished, or built around a subscription instead of around me. None of them fit what a real day with diabetes actually looks like: meds, meals, doctor visits, blood pressure, all connected. So I built the app I actually needed."
Everything you need.
Nothing you don't.
Built by someone who understands that managing diabetes is serious work — GlucoBeacon gives you clinical-grade tools in a clean, simple interface.
Blood Sugar Tracking
Log readings instantly with color-coded feedback. See 7-day trends, time-in-range rings, and a full history of every reading you've ever taken.
A1C Estimator
A real-time A1C estimate using the ADA's Nathan formula, recency-weighted over your last 90 days. No lab required.
AI Diabetes Assistant
Ask real questions and get answers personalized to your actual readings, A1C, medications, and goals — not generic health advice. Powered by Claude AI.
Meal History
Log that grilled chicken sandwich again? See exactly what happened last time — your before-meal reading, any meds you took, the after-meal reading with the actual rise, and whether a walk afterward made a difference. Your own data becomes your best guide, automatically, every time you eat something you've had before.
New: Fasting Tracker
Start a fast in one tap with 16:8, 18:6, 20:4, OMAD, or your own custom window. A live countdown and progress ring keep you on track in the app, and your home screen widget counts down right alongside you — "Under 1 hour left," "10 min left," "Time to eat!" Forgot to start it on time? Correct the start time after the fact and everything recalculates instantly.
Restaurant Advisor
Eating out? GlucoBeacon scores every item at 53 major chains — McDonald's, Chipotle, Panera and more — by glycemic impact, carbs, and calories against your personal goals.
Workout Library
18 evidence-based routines across beginner, intermediate, and expert levels — each with diabetes safety notes, science citations, and a guided timer-based player.
Medication Tracking
Autocomplete across 120+ diabetes and blood pressure drugs, with up to 3 daily reminders per medication so you never miss a dose.
Pantry & Recipes
Scan items into your pantry with a barcode scanner. Browse 120 diabetic-friendly recipes and see what percentage of ingredients you already have.
Blood Pressure & Weight
Track your full cardiovascular picture alongside blood sugar. Trend charts, history logs, and lifestyle summaries in one place.
Health Connect Sync
Connect your Fitbit, Garmin, Samsung Watch, or Wear OS device. Steps, weight, blood pressure, sleep, and workouts sync automatically via Android Health Connect.
Appointments
Keep every doctor visit on a built-in calendar with reminders, and get warned automatically if two overlap. Ask your AI assistant to book one for you.
Home Screen Widget
Log a reading, a med, or check your steps without even opening the app — tap the widget's mic and just say it, glance at your latest numbers, or watch your fasting countdown tick down, all from your home screen.
Real screens. Real data.
Every screen is designed to surface the information you need — fast. No clutter, no noise.
Built for every type of diabetes.
Whether you were diagnosed last month or have managed your condition for decades, GlucoBeacon meets you where you are.
Type 1 Diabetes

Your health data belongs to you.
In an industry where health data is bought and sold, GlucoBeacon is different. Everything stays on your device — always.
No Account Required
Open the app and start logging. No email, no password, no profile to create.
On-Device Storage
Your readings, medications, and logs live in an SQLite database on your phone — never uploaded, never synced to us.
No Data Selling
We don't collect, analyze, or sell your health information. There is no "us" in your data.
Optional Backup
If you want backup, connect your own Google Drive. The file goes to your account, not ours.
Anonymous Crash Reports
If the app ever crashes, a technical report — device model and error trace, never your health data — helps us fix it. That's the only thing sent automatically.
Straight answers.
The things people actually ask before trusting an app with their health data.
There's no account system, and your health data — readings, medications, appointments, food logs — lives in a local database on your phone and is never uploaded automatically. If you want a backup, it goes to your own Google Drive, not ours. Two narrow, disclosed exceptions: if the app crashes, an anonymous technical report (device model and error trace — never your health data) is sent to help us fix the bug; and if you choose to use the AI Assistant or AI Food Scan, that specific message or photo is sent to generate a response and isn't stored afterward.
Good for fresh, homemade, and restaurant meals — that's what it's built for. For packaged products, use the Barcode Scanner instead: it pulls real nutrition data from Open Food Facts rather than estimating from a photo, so it's exact where AI estimation can't be. Get it wrong? One tap removes a misidentified item and instantly recalculates your total. Missed something? Type it in and get an instant separate estimate for just that item — no need to retake the photo.
Blood sugar logging, medication tracking and reminders, the step counter, and the home screen widget are free, permanently, with no trial clock. Pro unlocks everything else — meal history, full A1C trends, restaurant advisor, workout library, AI assistant, and more — and every plan starts with 14 days of Pro free, so you can try the complete toolkit before paying anything.
No — and that's on purpose. GlucoBeacon is built around traditional finger-stick logging, which is still how most people with diabetes actually monitor, whether by choice, doctor's guidance, or because a CGM isn't covered by insurance. Health Connect sync covers steps, weight, blood pressure, sleep, and workouts from your phone or watch. We don't currently offer real-time CGM streaming — if that's a must-have for you, apps built around a specific CGM will serve you better.
Yes — that's what the Doctor PDF Report is built for. It compiles your readings, A1C estimate, and patterns into a report formatted for a real appointment, not a raw data dump.
Every Pro plan — monthly or annual — starts with 14 days of full access, free. Google Play requires a payment method on file to start the trial, but you won't be charged until it ends, and you can cancel anytime before then with no charge at all. Lifetime purchases are a one-time payment and aren't part of the trial.
