I wanted an AI that knew my whole protocol.
I’m on peptides and TRT, same as you. I got tired of digging through message boards for a post that kind of matched my protocol, then trying to figure out if the advice even applied to me. So I made a coach that already knows my whole stack and answers for my situation. I built it for me. I use it every day.
INSIDE THE APP
NOW AVAILABLE
Stackeddd is live.
Free on the App Store and Google Play. No account, no card to start — your data stays on your phone.
WHAT IT DOES
AI COACH
Not a correlation engine. Not a chatbot. An actual coach that knows your stack, protocols, labs, sleep, training, and goals — and answers with your real data. Trained on a curated peptide and HRT knowledge base, not generic. Asks before it advises.
DOSE TRACKING
Peptides. HRT. Supplements. Meds. Injectable, oral, gel, nasal — every dosage form, every protocol. Curated compound lists, photo label scan, on/off-week cycling, and side-effect tracking the AI Coach uses for pattern detection.
CALCULATORS
Seven of them. Peptide reconstitution. Pre-mixed HRT dosing. HGH IU↔mg. Custom blends. Nasal spray reconstitution. Cream clicks. Half-life modeling. The math you shouldn’t be doing in your head.
LAB PARSING
Drop in any lab PDF. The app extracts your values, flags out-of-range markers, and tracks every marker over time as a real chart you can scrub.
BLOOD LEVELS
Pharmacokinetic curves per compound, computed from your real injection log. Peak. Trough. Average. Stacked across protocols so you can see what’s actually circulating.
CYCLE TRACKING
Built for women on testosterone, estrogen, progesterone, or peptide protocols. Period history, phase-aware lab interpretation, daily symptom logging. Hormone labs auto-stamp with the cycle day they were drawn, so the AI Coach reads E2 against where you actually were in your cycle.
HEALTH SYNC
Apple Health on iOS. Health Connect on Android. Nutrition, sleep, and fitness — pulled in, attributed to source, deduplicated across overlapping apps, and visible alongside your stack.
WHO BUILT THIS
I built Stackeddd because I was curious if I could.
I’m in the HRT and peptide community — running protocols, tracking labs, reading the forums. I built this app with every feature I wanted in a peptide and HRT tracker. I never tried any of the other apps in this space, so I genuinely don’t know what they have or don’t have. I just knew I didn’t want something that felt cold and clinical for what’s actually a pretty personal thing. So I started building.
Local-first because I don’t want my own data leaked any more than you do. An AI Coach that talks to you like a person who knows what you’re running. No analytics, no ads, no growth team. Just the app I wanted to use.
I gave it to a friend because I thought it might help him. He gave it to a friend. That friend gave it to someone else. That’s how Stackeddd has spread so far — handed around the community by people who tried it.
I’m not trying to get rich off this. The goal is to cover the costs of running it and build something genuinely useful to people on their HRT and peptide journeys. If that’s you, give it a shot.

DATA OWNERSHIP
Your data lives on your phone. Not on a server.
That’s the whole point.
No accounts. No analytics. No cloud.
- NO ACCOUNT. No login, no signup, no email collected. The app works the moment you install it.
- NO ANALYTICS. We don't track sessions, taps, or what you log. We don't know if you opened the app today.
- NO CLOUD STORAGE. Your stack, protocols, and labs are written to your device, not our servers. AI messages are sent to the AI provider only to generate a reply, never stored by us.
- EXPORTABLE, ALWAYS. Settings → Provider Report for a doctor-ready PDF, or full JSON backup of everything else. You own it. Period.
