Track peptide doses, lift PRs, daily macros, body comp, and AI-parsed lab results in a single timeline. Built for operators who want signal, not noise.
Doses, workouts, meals, body comp, and bloodwork all live next to each other — so when you change something, you can see what moved.
Reconstitution math, syringe calculator, dose reminders, site rotation. Injectable, oral, or pre-mixed — Stack adapts to the form factor.
211-exercise library, custom movements, automatic PR detection (Epley 1RM), confetti when you hit one. Share to feed in one tap.
Quick templates or manual entry. Daily macro progress against your targets, woven into the same timeline as your doses and lifts.
Weight, body fat, measurements. 30-day deltas. Inline sparkline so you see whether the trend is going your way.
Snap a lab report, Stack pulls every biomarker into a structured view grouped by domain. Trend each one across uploads.
ProTell Stack your goal — "fat loss + better sleep" — and get a research-backed peptide stack, fed by your latest bloodwork and active protocols.
ProFollow operators with similar goals. Posts, comments, bookmarks, trending peptides. Public to browse, login required to interact.
Color-coded daily dots show every dose, workout, meal, and weigh-in at a glance. Tap any day to replay it.
Recovery, weight loss, muscle, sleep, longevity — Stack uses your goals to seed your starter pack and recommended reading.
Pick a peptide. Stack walks you through reconstitution, dose math, and reminder cadence. No spreadsheet required.
Doses, workouts, meals, weigh-ins — everything stacks on the daily timeline. Upload bloodwork and watch markers trend.
No credit card to start. Pro unlocks the heavy AI features — bloodwork OCR and the recommender.
No. Stack is for educational and research-tracking purposes only. Nothing in the app — including AI recommendations — is medical advice. Always consult your physician before acting on protocol changes or bloodwork results.
Yes, via the web build today. The native iOS app is in TestFlight prep — once it lands, you'll be able to install it from the App Store. Apple Health sync follows shortly after.
Upload a photo or PDF of your lab report. Stack sends it to Claude (Anthropic's frontier vision model) which extracts every biomarker, flags out-of-range values, and groups them by domain (Hormones, Metabolic, Lipids, etc.). Pro tier, 5 uploads per day.
Supabase (Postgres + secure storage). Encrypted at rest, owner-only read/write via row-level security. You can delete your account and all associated data at any time.
Yes — when you tap "Where to buy" on a peptide page, Stack links you here. That's it. No payment data flows from the storefront into the app, and no tracker data flows out of it.
Yes. Cancel from your account settings — keep all features through the end of your billing period, then drop to Free with no data loss.
Free to use. No credit card. Open the web build in the next tab and have your first protocol logged before you finish your coffee.
