Sustain: GLP-1 Tracker & Coach

On a GLP-1, up to 40% of what you lose can be muscle. Sustain is the companion that protects it: protein-first meal scans, shot tracking, side-effect coaching, and the only taper plan for life after. Built for Ozempic®, Wegovy®, Zepbound® and Mounjaro® users. Not affiliated with any manufacturer.

PROTEIN-FIRST MEAL SCANS Snap any meal — even a tiny one — and get protein math in seconds, plus the smallest fix to reach your daily floor.

YOUR PROTEIN FLOOR Calculated from your goal weight (1.2–1.6 g/kg): the minimum that protects muscle while the weight comes off.

SHOT TRACKER WITH SITE ROTATION A body map that remembers where you injected and suggests the next site. Reminders on your schedule.

SIDE-EFFECT COACH Log nausea, fatigue, constipation in one tap. See your personal pattern by day-after-shot, with evidence-based mitigation tips.

MUSCLE GUARD TRENDS Weight pace vs. the expected range, protein-floor streaks, and a weekly strength check-in — plain-English verdicts, not just charts.

TAPER MODE The only structured off-ramp: adjusted targets and coaching for keeping the results after the medication.

PRIVATE BY DESIGN No account. Your data stays on your device (and your own Apple Health). AI analysis is transient — nothing is used to identify you.

MEDICAL DISCLAIMER Sustain is not a medical device and does not diagnose, treat, or prescribe. It is an educational and tracking tool. Always consult your doctor or prescriber before making any medical decision, and never start, stop, or change a medication or dose based on this app.

SUBSCRIPTION Sustain Pro is an auto-renewable subscription, offered on a weekly or a yearly plan. The exact price, and the length of any free trial you are eligible for, are shown in the app before you buy. Payment is charged to your Apple Account when the free trial ends — or at the time of purchase if the plan has no trial — and renews automatically for the same period unless you cancel at least 24 hours before the current period ends. Manage or cancel in Settings > Apple Account > Subscriptions.
