Stackr is the simplest way to track peptide and GLP-1 dosing. Log every dose. Track vials, pens, tablets, and other containers with how much you have left. Get reminders for your next dose. See how half-life shapes estimated active levels in your stack over time. Built for peptide enthusiasts, GLP-1 users, and anyone who wants their protocol off paper and into an app that understands supplies and dosing cadence — not a generic habit tracker. WHY STACKR • Fast dose logging — log from home or tap the widget when you're in a hurry • Supplies — track what's in the fridge (vials, pens, bottles, sprays, and more) with amounts, low-stock alerts, and typical dose size so "doses left" stays honest • Multi-peptide stacks — run BPC-157 alongside a GLP-1 (or anything else you track) in one place • Active levels — visualize estimated active amount over time from your logged doses and each peptide's half-life (educational estimate, not medical guidance) • Reminders & widgets — next-dose reminders that respect your schedule; home-screen widgets for what's due PEPTIDE LIBRARY Stackr includes reference pages for the most-tracked compounds — semaglutide, tirzepatide, retatrutide, BPC-157, TB-500, MK-677, GHK-Cu, and more. Each page covers typical dosing, half-life, schedule, route, mechanism, and general education. Educational only — Stackr is not medical advice. REMINDERS THAT FIT YOUR PROTOCOL Set reminders aligned with how you dose — daily, every other day, weekly, or custom intervals. Use widgets to see what's next without opening the app. SYNC ACROSS YOUR DEVICES Sign in with Apple or email and your data syncs across iPhone and iPad. Encrypted in transit. Your dosing history stays tied to your account — no ads, no selling data to third parties. BUILT FOR THE PEPTIDE COMMUNITY: By a peptide user, for peptide users. If something's missing, the in-app feedback channel goes straight to the founder. —— Disclaimer: Stackr is for personal tracking only and does not provide medical advice.
