GLP-1 Shot Tracker – Cerni

On a GLP-1, up to 40% of what you lose can be muscle.
Cerni protects it: protein-first meal scans, shot tracking, side-effect coaching, and the only taper plan for life after.
No account. No sign-up. Your data stays on your iPhone.

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. Wrong estimate? Edit any item; the app never locks you into a bad number.

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 — the one that has had the longest rest. Reminders on your schedule.

SIDE-EFFECT COACH
Log nausea, fatigue or 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 & MAINTENANCE MODE
The only structured off-ramp: adjusted targets and coaching for keeping the results after the medication.

YOUR DATA CANNOT BE LOST
No account to create, no server to lose it on. Everything lives on your iPhone and your own Apple Health. AI analysis is transient — nothing is used to identify you, and you can export or delete it all at any time.

Cerni is a wellness companion, not medical advice. Never change your dose without your prescriber.
