Peptide Tracker: Stackeddd

About this app

The dose calculators, blood-level charts, reminders, and full protocol tracking are free — no trial, no paywall, no catch. Most peptide and TRT apps charge for exactly this. I don't.

Stackeddd is built for people running serious peptide and TRT/HRT protocols. Track every injection, watch your blood levels rise and fall between doses, run the dose and vial-mix math, and never miss a shot. The AI coach — the one paid feature — reads your own labs, protocols, and injection history, and it's built to say "I don't know" instead of guessing.

WHAT'S FREE (and stays free)

• Dose, blend, and half-life calculators
• Blood-level PK chart — peak, trough, and steady-state, per compound
• Injection logging with site rotation
• Full inventory — every peptide, HRT compound, GLP-1 (semaglutide, tirzepatide), supplement, and med
• Phased protocols with automatic on/off scheduling
• Titration schedules — gradual dose adjustments over weeks, auto-stepping
• Lab result tracking and trend charts
• Macro logging
• Sleep, fitness, and weight sync from Apple Health or Health Connect
• Reminders and notifications
• JSON export, anytime

No account. No analytics. No cloud. Your health data lives on your phone. I can't see it, sell it, or lose it.

THE AI COACH (Pro)

Not a chatbot. Not a correlation engine. An actual coach with direct access to your full health context — labs, protocols, peptide stack, GLP-1 doses, nutrition, sleep, fitness, side effects — plus a curated knowledge base of peptide and HRT references. It reads a lab PDF, scans a supplement label, analyzes a side-effect cluster, and explains it in plain language. Grounded in your own data, not the internet's.

Pro is $9.99/mo or $59.99/yr: unlimited AI coach conversations with photo attachments, unlimited lab PDF parsing, and unlimited nutrition and supplement-label scans.

WHO BUILT THIS

Stackeddd is a one-person project. I'm in the HRT and peptide community myself, and I wanted a tracker that didn't feel cold and clinical — so I built the one I wanted, with every feature I needed.

I had my wife test it the whole way through, so it isn't built only for the guys. She told me what women actually need in a tool like this — cycle-aware tracking, the right hormone panels, and a tracker that doesn't assume everyone's a man on TRT. It's all in here.

I gave it to one friend, hoping to help him. He gave it to another. That's how Stackeddd has gotten everywhere it's gotten so far. No ads. No growth team.

The mission isn't to get rich. It's to cover the cost of running the app and build something genuinely useful to people on their HRT and peptide journeys. The AI Coach engages with compounds, doses, and protocols directly — but it's not a doctor. Always discuss any protocol change with your prescribing physician.

Ratings and reviews

I’ve been looking for a secure, streamlined way to keep track of my routine, and Stackeddd hits the nail on the head. Managing peptides, HRT, and supplements in one place used to require a messy spreadsheet, but this app makes it effortless. ​The standout feature is definitely the built-in AI coach—having something that can actually look at your custom stack alongside your lab work is a game-changer for staying on top of your health. On top of that, knowing it's built with privacy in mind.

Stackeddd has completely changed how I manage my protocols. The app keeps my pins, doses, units, timing, titration schedules, and reminders organized without having to manage everything with my phone calendar. Inventory tracking helps me stay ahead, but the AI coach is the real standout. Its curated knowledge base saves me hours of research on HRT, peptides, fitness, and nutrition. This app is organized, useful, and clearly built for people who take their health and performance seriously.

Just started on this journey looked at several different trackers and they just seemed clunky and unintuitive. I also prefer the privacy this offers, in a world full of companies selling data it's refreshing to have on that is actively distancing itself from mine.

What’s new

New: a built-in Compound Library. Look up 130+ peptides and hormones for typical doses, half-lives and how they work, or tap the book icon on anything in your Inventory or Stack to jump straight to it.

Also new: body-weight tracking with a trend chart, off-schedule extra doses, and an optional injection site so you can log a shot in fewer taps.

Fixed: light-mode readability, pop-ups getting cut off on some phones, and faster, smoother navigation throughout.
