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, Apple Health and the week-by-week guide are all free. Pensday Plus adds AI food logging and the 3D body scan. 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, dose reminders with their own sound, a home-screen widget and a Live Activity. 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 With Pensday Plus, a short guided capture estimates body fat, muscle and measurements, processed entirely on-device. Your body-scan photos never leave your iPhone. 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. APPLE HEALTH, BOTH WAYS Weight, meals, water and body composition you log flow into Apple Health. Steps, active energy and weight from your other apps flow in. 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. — PRIVATE BY DESIGN — • No account needed. Anonymous first; sign in with Apple, Google or email only if you want a backup. • No ads, no data selling, no tracking across apps or websites. • Body-scan photos are analysed on-device and never uploaded. • Export or delete everything, any time, right in the app. — TIRO PLUS — AI food logging by photo, voice, text and nutrition label, and the private 3D body scan. $19.99 per month or $59.99 per year (US), with a 7-day free trial on the annual plan. Everything else stays free. Pensday is a tracking companion, not a medical device, and never recommends a dose. Medication-level estimates and body measurements are approximate. Follow your prescriber. Pensday is not affiliated with any pharmaceutical manufacturer; medication names are trademarks of their owners.
