GLP1 Tracker

Read full description

Precision is the private, no-account GLP-1 tracker built for people using Ozempic®, Wegovy®, Mounjaro®, Zepbound®, Semaglutide, or Tirzepatide. Log every shot, watch your progress unfold, and stay ahead of side effects — all without creating an account or sending your health data to the cloud. WHY PRECISION • No account required — open the app and start tracking in seconds • Your data stays on your device, not on a server • A clean, fast interface built specifically around the GLP-1 journey DOSE & INJECTION TRACKING Log each injection in one tap. Precision rotates your injection sites for you to help prevent tissue irritation, tracks your titration schedule as your dose increases, and warns you before you miss a shot. PROGRESS & WEIGHT ANALYTICS See your weight velocity, not just the number on the scale. Precision charts how your weight loss trends alongside your dose and timeline, so you can see what's actually working. HUNGER, PROTEIN & NUTRITION Track hunger levels throughout the day and set protein targets to support muscle mass while you lose weight — a key concern for anyone on a GLP-1 medication. SIDE EFFECT & SYMPTOM LOG Quickly log nausea, constipation, and other symptoms so you and your provider can spot patterns over time. MEDICATION SUPPLY TRACKING Never get caught without your next dose — log your pen/vial inventory and know exactly when to refill. HEALTH CONNECT SYNC Precision connects with Google Health Connect to bring in your weight and activity data automatically, so you spend less time on manual entry. Precision supports Semaglutide (Ozempic®, Wegovy®), Tirzepatide (Mounjaro®, Zepbound®), and other GLP-1 medications.
