About Glev – Diabetes & CGM Tracker
Your diabetes logbook that listens: log meals by voice, see your blood sugar live from your CGM, spot patterns — all on one screen. Instead of fighting a clunky food-database form, you just talk: "A slice of margherita pizza and a small yogurt." Glev understands what you ate and logs carbs, protein, fat and fiber for you — in under 10 seconds. Alongside it, your glucose curve updates live — straight from LibreLinkUp, Nightscout or Apple Health. No app-switching, no manual copying. Your meal and your glucose response: one screen. WHY GLEV Living with Type 1 means thousands of tiny decisions every day. Counting carbs at dinner, remembering when you last ate, what you ate, and how it played out on your glucose curve. Most apps make you fight a form. Glev listens. VOICE-FIRST LOGGING - "I had a slice of margherita pizza" — logged with full macros - "Ran 5k this morning" — added to your timeline - Activities, stress, sleep quality — all captured by voice, all searchable LIVE GLUCOSE TIMELINE See your glucose, meals and activity side-by-side. Spot patterns. Understand what works for your body. Share a report with your endocrinologist or diabetes educator in one tap. WORKS WITH YOUR LIFE - LibreLinkUp, Nightscout and Apple Health integration — read glucose from your CGM - Offline-capable — you don't lose data if you lose signal - Privacy by design — encrypted, GDPR-compliant, servers in the EU, never sold WHAT GLEV IS NOT Glev does not replace your doctor and does not make therapy recommendations. It shows you patterns from your own history — what you take from them, and what you discuss with your care team, is up to you. Glev is a documentation tool, not a medical device. BUILT BY A T1D, FOR T1DS Glev was started by a Type 1 diabetic who got tired of fighting his own logbook. Every design choice — from voice-first input to the meal-logging flow — comes from real life with insulin, CGMs, and the math we all do at every meal. PRICING - Free: core logbook with voice logging, manual entry and history - Glev Smart (€8.99/month): log everything by voice, meal + insulin + glucose linked, live CGM curve - Glev Pro (€18.99/month): everything in Smart plus Adapt Score, CGM-based insights and a direct line to the founder - Glev+ (€28.99/month): everything in Pro plus doctor reports as PDF — built for parents and caregivers of kids with T1D Subscriptions are billed through your App Store account and can be cancelled anytime. Free trial available. Important Notice: Glev is a documentation and lifestyle app and does not replace medical advice. Glev does not provide diagnoses or treatment recommendations and is not a medical device. Always consult your physician, diabetes educator, or qualified healthcare professional for any medical questions or treatment decisions. In case of emergency, contact emergency services immediately (112 in Germany, 911 in the US). Privacy Policy: https://glev.app/legal?tab=dse Terms of Use (EULA): https://glev.app/legal/eula
