Pensday is the GLP-1 tracker for weight loss shots and pills. Log every dose, see your estimated medication level, hit your protein, and find out if you're losing fat or muscle with a private 3D body scan on your own phone. Works with Ozempic, Wegovy (pen and pill), Mounjaro, Zepbound, Rybelsus, Saxenda, Victoza, Trulicity, compounded semaglutide and tirzepatide, and Retatrutide. NEW: SCORE EVERY MEAL Every meal you log gets a score made for eating on a GLP-1: protein and fiber count most. Each score comes with one simple tip to raise it, and your Day score shows on Home and in Food. Prefer words to numbers? Show labels, or turn scores off. NEW: YOUR LEVEL ON YOUR HOME SCREEN The Pensday widget shows your estimated medication level, protein, water and next shot. Tap + to add protein or water without opening the app. Your level also sits on your Lock Screen, and Pensday shows you how to add the widget in 3 taps. NEW: A COMMUNITY OF PEOPLE ON A GLP-1 Ask questions, share what works and save the posts that help you. Earn badges for showing up and see where you stand in the League. NEW: PENSDAY IN 8 LANGUAGES English, German, Portuguese (Brazil), Spanish (Latin America), Japanese, Korean, Arabic and Simplified Chinese, including the guided 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 half-life, dose and route behind it explained in the app. NEVER MISS A SHOT Next-shot countdown, dose reminders with their own sound, the widget and a Live Activity. Late dose? An adaptive schedule eases you back to your shot day. See every dose step on a calendar before it arrives. ROTATE YOUR INJECTION SITES A 12-zone body map shows every shot as a dot, so you see which spot needs a rest. TRACK SIDE EFFECTS BY DOSE Log nausea, constipation, fatigue, food noise, cravings, mood and more on a quick scale, then see how they move across your dose cycle and each step. PROTEIN-FIRST FOOD LOGGING Snap a plate, scan a barcode or label, say it or type it. Pensday estimates calories and macros with protein and fiber first, sets a protein target to protect your muscle and keeps calories above a safe floor. Food photos are never stored. A PRIVATE 3D BODY SCAN With Pensday Plus, a short guided capture estimates body fat, muscle and measurements, processed entirely on your iPhone. Your body-scan photos never leave your phone. Watch fat and muscle change scan to scan and see your weight trend at each dose. YOUR WEEK-BY-WEEK GUIDE What to expect at your dose and week, and questions to bring to your prescriber, built from the official prescribing information. APPLE HEALTH, BOTH WAYS Your weight, meals, water and body composition flow into Apple Health; steps and weight from other apps flow in. SHARE WITH YOUR CLINIC, ONLY IF YOU WANT A six-character code links you to a clinic that uses Pensday. You choose what they see and can disconnect at any moment. PRIVATE BY DESIGN • No account needed; sign in only if you want a backup. • No ads, no data selling, no tracking across apps. • Export or delete everything, any time. PENSDAY PLUS AI food logging by photo, voice, text and nutrition label, and the private 3D body scan, as a monthly or annual subscription. Shots, medication level, reminders, dose steps, injection sites, side effects, weight, water, scores, community and the guide need no subscription. 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.

Verdict

The call

The clearest difference is monetization model: Pensday at free with in-app purchases against SimplyDose's subscription. Pensday also leads on iOS requirement (15.1 vs 17.0). SimplyDose's advantage is update cadence (weekly vs every 3 weeks). On price, rating, review sentiment and ratings volume there is nothing between them.
