GLP-1 dose tracker with injection reminders, weight log, calorie tracking, side-effect charts and your full injection/pill schedule in one place. Log your medication, see how levels may change over time, understand side effects at a glance, and keep weight and daily habits in one calm place. Works with GLP-1 therapies and weight-management medication—including Ozempic, Wegovy, Mounjaro, Zepbound, Saxenda, Victoza, Trulicity, Rybelsus, semaglutide, tirzepatide, liraglutide, dulaglutide, and Retatrutide. WHY GLYRA Weight loss Progress & BMI: Track your weight loss overtime and view your BMI on a simple gauge, alongside dose status and what’s coming next on your schedule. Estimated medication levels: Glyra models how your level may rise and taper between logged doses — with separate curves for tirzepatide, semaglutide, and retatrutide based on your dose history. A visual way to connect timing, amount, and how you feel between doses. Side-effect snapshot chart: See side effects on a spider-style chart so patterns stand out quickly — useful for your own notes and for conversations with your care team. Share Your Journey (camera graph filter): Capture a photo with your weight-progress graph overlaid on the image — made for sharing milestones without rebuilding a chart in another app. Visit-ready CSV & PDF export: Export a formatted PDF summary (weight change, dose and side-effect overview) plus CSV for spreadsheets. Built for records you may want to bring to an appointment. CORE TRACKING • Dose log — medication, amount (mg), injection site, pain level, notes, scheduled vs completed • Calendar & daily log — weight, calories, protein, water, and general notes by day • Weight & progress charts — follow trends across flexible time ranges • Dose reminders and optional daily check-in reminders • Light and dark appearance PRIVATE BY DESIGN • No sign-in account — your tracking data stays on your device • Delete all app data anytime in Settings WHO IT’S FOR Adults using GLP-1 medications who want dose scheduling, level estimates, side-effect visibility, calorie/nutrition logging and weight tracking in one focused app — without ads for unrelated products or a cluttered social feed.
