Pensday is the all-in-one GLP-1 tracker for weight loss shots and pills. Log every dose, see your estimated medication level, track food, side effects and weight, and scan your body privately on your own phone.

Works with Ozempic, Wegovy (pen and pill), Mounjaro, Zepbound, Rybelsus, Saxenda, Victoza, Trulicity, compounded semaglutide and tirzepatide, and retatrutide.

— FREE TO USE —
Shots, medication level, reminders, dose steps, injection sites, side effects, weight, water, streaks, Health Connect and the week-by-week guide are all free.

SEE YOUR MEDICATION LEVEL
Log a shot in seconds and watch an estimated medication-level curve for semaglutide, tirzepatide, liraglutide, dulaglutide and retatrutide. Solid for the past, projected ahead, with the pharmacology behind it (half-life, dose, route) explained in the app. Free, not locked behind a subscription.

NEVER MISS A SHOT
Next-shot countdown and dose reminders with their own sound. Late dose? An adaptive schedule eases you back to your shot day instead of breaking it. Streaks and badges make consistency feel good.

KNOW WHEN YOUR DOSE STEPS UP
See your dose steps on a calendar before each one arrives, so a step-up never sneaks up on you.

ROTATE YOUR INJECTION SITES
A body map with 12 zones, the belly split in four. Every shot you log shows as a dot, so you can see at a glance which spot needs a rest.

TRACK SIDE EFFECTS BY DOSE
Log nausea, heartburn, constipation, fatigue, headache, hair loss, food noise, cravings, mood, energy and shot anxiety on a quick severity scale, then see how they move across your dose cycle and each dose step.

PROTEIN-FIRST FOOD LOGGING
Snap a plate, scan a barcode or nutrition label, say it or type it. Pensday estimates calories and macros with protein and fiber first, sets a protein target to protect your muscle, keeps calories above a safe floor, and balances fiber and water for easier digestion. Food photos are processed for the estimate and never stored.

A PRIVATE BODY SCAN, ON YOUR PHONE (BETA)
A short guided capture estimates body fat, muscle and measurements, processed entirely on-device. Your body-scan photos never leave your phone. Watch fat and muscle change scan to scan, add progress photos, and see your weight trend at each dose on the way to your dream weight.

YOUR WEEK-BY-WEEK GUIDE
What to expect at the exact dose and week you are on, what is worth logging, and the questions to bring to your prescriber, built from the official prescribing information.

HEALTH CONNECT
Pensday reads your steps and active energy from Health Connect so your dashboard reflects your whole day, including activity logged in other apps.

SHARE WITH YOUR CLINIC, ONLY IF YOU WANT
If your clinic uses Pensday, a six-character code links you. You choose what they can see, every view is recorded for you to read, and you can disconnect at any moment.
