Stackeddd tracks peptide and TRT protocols: every injection, site rotation, vial math, and a real PK chart showing blood levels rise and fall between doses. The AI coach reads your own labs, protocols, and logs - and is built to say "I don't know" rather than guess, tested against ~60 adversarial scenarios before every release. No account, no cloud, no analytics. Your data stays on your phone. Everything that keeps you safe is free; the coach is the paid part.

Hey Product Hunt. Jay here, and I'm the only person on this.
I built Stackeddd because I needed it. I'm in the HRT and peptide community, running protocols and tracking labs, and I wanted a tracker with every feature I wanted in one, without it feeling cold and clinical for something that's actually pretty personal.
The part I'd want your feedback on is the AI. Every tracker in this space bolted a chatbot on last year. In a category where wrong advice goes into someone's body, that scared me more than it impressed me. So the coach only works from your actual logged data, it's built to say "I don't know" instead of reassuring you, and I run it against a suite of ~60 adversarial scenarios before every release specifically to catch it inventing numbers. That eval harness is the product, as far as I'm concerned.
It's local-first: no account, no cloud sync, no analytics. I can't see your data, sell it, or lose it. Full JSON export whenever you want out.
Everything that keeps you safe is free: calculators, protocols, blood-level charts, logging, reminders. The AI coach is the only paid part, because it's the only part that costs me money to run.
It got everywhere it's gotten by one friend handing it to another. This is the first time I've put it in front of a room of builders, so: tell me where it's wrong.
