PeptideCore vs Peptily

The most complete protocol tracker for serious GLP-1 and peptide users. Track Ozempic®, Wegovy®, Mounjaro®, Zepbound® — or any peptide stack — with pharmacokinetic curves, a stack-interaction checker, and a citation-backed library no other tracker offers. PeptideCore is the private, on-device companion for GLP-1 patients, peptide stackers, microdosers, and biohackers who want a clean visual record of every shot, dose, and side effect. No ads. No data sold. No bro-science. Built by an iOS engineer who tracks their own protocol. FREE TO USE Log every dose, rotate injection sites, run the reconstitution calculator, and browse the peptide library — free, no account required. PeptideCore Pro is optional. WHAT YOU GET WITH PRO • Estimated medication-level curve. See how semaglutide, tirzepatide, retatrutide, or any peptide with a known half-life decays over the past week — with peak and trough markers. • Visual injection-site map. Front and back body view with 14 sites. Each site color-codes by days since last use so you rotate intelligently. • Dose-coded weight chart. Your weight line is colored by current dose tier so the weight loss response to your Mounjaro® or Wegovy® titration is visible at a glance. • Reconstitution calculator. Forward (dose → units), reverse (target draw → BAC water), and multi-peptide blend modes. Supports U-100, U-40, and tuberculin syringes. • Curated peptide library. 25+ entries with typical dose, half-life, route, and a tap-through PubMed citation. Covers BPC-157, TB-500, CJC-1295, Ipamorelin, MOTS-c, GHK-Cu, PT-141, Tesamorelin, and more. • Stack interaction checker. Flags overlap between active compounds with severity grading and PubMed-linked citations. • Inventory tracking. Vial-by-vial stock with expiry dates, reorder reminders, lot numbers, and cost per dose. • Live Activity countdown. Your next shot lives on your lock screen and Dynamic Island. • Apple Health integration. Pulls weight, HRV, sleep, and resting heart rate to correlate with your protocol. • Private on-device AI. Apple Intelligence flags adherence trends, symptom patterns, and site rotation balance — without sending your data anywhere. • Share card export. Render a branded progress card to celebrate weekly wins.

Peptily keeps your injection protocol in one place: the dose your prescriber gave you, when it is due, which site to use next, and when to replace the vial. YOUR DOSE, AS PRESCRIBED Enter your dose from your prescription or pharmacy label. Peptily shows it on every reminder exactly as you entered it. NEVER MISS A DOSE A reminder on dose day and one follow-up if it is still due, not a stream of notifications. Your next dose also lives on the Lock Screen, in the Dynamic Island and in a Home Screen widget with a Log button. DOSE STEPS ON YOUR DATES If your prescription changes the dose over the weeks, enter each step once. Reminders and Today follow your steps, so you stop counting weeks in your head. SITE ROTATION YOU CAN SEE Eight sites, color-coded by how recently each was used, with the least recently used one up next. Hitting rested tissue is the whole point. VIAL DATES Note the day you started a vial and the replace-by date from your label. Peptily reminds you three days ahead, so your protocol does not gap. BUILT FOR STACKS Every compound gets its own dose, reminder and site. Switch between them on Today and log each one in a tap. YOURS, ON YOUR DEVICE No account. No sign-up. No server. Your protocol never leaves your phone. Edit or delete any entry, and log a missed dose later. Export a clean PDF when you want to show your clinician. HOW IT WORKS Your first logged dose is on us, with every feature open. After that, Pro keeps the log going, along with dose steps, unlimited compounds and stacks, the site rotation map, your full history with a weight trend, and PDF export. Whatever you have already logged stays readable for free, always. Peptily is a logging and reminder tool. It does not give medical advice or create treatment plans, and it does not sell or source anything. Follow your prescription and talk to your clinician about your protocol. — LEGAL — Pro is a weekly, monthly or yearly subscription, or a one-time Lifetime purchase.
