GLP 1 Tracker
Read full descriptionHide full description
Track every GLP-1 shot or pill and finally understand your week: when your medication rises and falls, and when the food noise comes back. hush logs your weekly shot, daily pill or compounded semaglutide and tirzepatide in seconds. It reminds you on shot day, rotates your injection sites and shows how your food noise, weight and side effects move with each dose. LOG A SHOT IN SECONDS Date, dose, injection site, how it felt. Each dose gets its own color, so a step up is easy to see. Backdated entries are fine, and everything stays editable. FOOD NOISE FIRST One tap a day: how loud was the food noise? Add nausea, energy and side effects when you want to. Blank means not logged, never "no symptoms". ROTATE SITES WITHOUT GUESSING A body map shows your last sites and suggests the next one. Switch off the spots you do not use. NEVER MISS A SHOT DAY A countdown to your next dose and one reminder at the time you choose. If your treatment is on hold, pause the reminders until you start again. WORKS WITH EVERY GLP-1 Ozempic®, Wegovy®, Wegovy® pill, Mounjaro®, Zepbound®, Rybelsus®, Trulicity®, Saxenda®, Victoza®, compounded semaglutide and tirzepatide, or add your own. Weekly, daily or twice a day.

Verdict
The clearest difference is in-app purchases: C3ntro at none against GLP 1 Tracker's 3. C3ntro also leads on device support (3 vs 1) and iOS requirement (14.0 vs 16.0). GLP 1 Tracker's advantage is ads (none vs shown) and update cadence (every 5 days vs every 3 months). On price there is nothing between them.
