Stack AI is a simple, private tracker for your medications, peptides and GLP-1 protocol. Log every dose in seconds, calculate reconstitution in one place, and review your history on a clean calendar — all in an app designed for consistency, not noise.
Whether you’re running a GLP-1 like Semaglutide (Ozempic, Wegovy), Tirzepatide (Mounjaro, Zepbound) or Retatrutide, or tracking a wider peptide stack (BPC-157, TB-500, Sermorelin, Ipamorelin, MT-II and more), Stack AI keeps your routine organized — without spreadsheets, sticky notes or screenshots.
YOUR STACK, ONE PLACE
- Add every medication or peptide to your shelf with strength, brand, and a quick visual cue.
- See remaining vial level at a glance with the live medication-level estimator.
- Catalog of 40+ peptides and GLP-1s with pharmacokinetic data (half-life, Tmax) sourced from FDA labels and clinical trials.
SMART SCHEDULES & REMINDERS
- Create recurring schedules per medication (e.g. "0.5 mg Mondays, 9:00 AM").
- Toggle reminders per schedule — get a notification before each dose.
- Today screen surfaces your dose to-do list for the current day.
ONE-TAP DOSE LOGGING
- Log a dose in seconds: medication, amount, time, injection site, notes, and pain level.
- Log doses for today or backdate past doses from the calendar.
- Each entry keeps a full record so you can spot patterns over time.
RECONSTITUTION CALCULATOR
- Take the guesswork out of mixing: peptide amount + BAC water → concentration, volume to inject, units on the syringe, syringe fill %, and doses per vial.
- Built around common insulin syringe presets.
PHARMACOKINETIC ESTIMATOR
- Visualize estimated medication level over 24 hours, 7 days, 30 days or 90 days.
- Combines your logged doses with upcoming scheduled doses so you can see where you are in your dosing window.
INJECTION SITE TRACKER
- Pick from anatomical sites when logging a dose.
- Weekly site heatmap shows which areas you’ve used the most so you can rotate properly.
DOSE HISTORY ON A CALENDAR
- A clean monthly calendar with every logged and scheduled dose.
- Tap any day to see what you took, when, where and at what dose.
- Switch to a chronological list view for a quick scroll through your history.
PROGRESS THAT YOU OWN

- See weight trend over time on a simple chart.
