How it works

The whole app,
screen by screen.

Pinned is a peptide tracker built like a tool, not a database. Here's what every screen does.

Today screen
Calculator screen
Coach screen
Today

Your daily
command center.

Every peptide you're running on one screen. Each card knows what you're taking, when it's due, how to draw it — and how many doses are left in the vial.

  • Big countdown to the next dose, per stack
  • One-tap logging — no menus, no forms
  • Streak counter so you don't slip on consistency
  • Site-rotation warnings when you're hitting one spot too often

Stack Optimizer · AI

An AI score
for your stack.

Pinned analyzes your peptides, your goals, and your timing — then gives you a single 0–100 score with the specific upgrades that would push it higher.

  • Goal coverage, timing, synergy — all scored in plain English
  • "What to fix" ranked top 5 changes that move the score the most
  • "What's working" highlights synergies you're already nailing
  • Specific dose / timing / site swaps — not generic advice

Calculator

The math,
done right.

Tell it your vial size and your dose. It tells you exactly how much water to add and which line to draw to on your syringe. No spreadsheets, no guessing, no mixing up mL with units.

  • Calculate water — picks a clean syringe tick (10, 15, 20 u) for you
  • Calculate units — for vials you've already mixed
  • Stack & Blend mode — multi-peptide vial math, automated
  • Won't-fit warning if your dose overflows your selected syringe

Vial Scanner

Scan a vial.
Get an A+ to F.

Point your camera at any vial label. Pinned reads the vendor and cross-references it against 270+ independently rated suppliers — sourced from Finnrick, Janoshik, and PeptideScores public lab data.

  • Instant letter grade based on real lab purity data
  • Auto-fills your inventory — vendor, lot, stability countdown
  • Catches sketchy vendors before you reconstitute, not after
  • Updated daily as new lab tests publish

Tracker

Every dose.
Every vial.

Three tabs in one: History, Body Map, and Inventory. Adherence, streaks, every dose you've logged, where you injected, and how much vial you've got left.

  • History — every dose grouped by day, with site and time
  • Body Map — anatomical heatmap showing which sites are cooling vs overused
  • Inventory — countdown to "use by" date per vial (28-day window)
  • Use This Site Next — Pinned suggests the optimal rotation site

AI Coach

AI that knows
your stack.

Powered by Claude. Ask anything about your peptides — timing, side effects, stacking, sourcing, cycling. It already knows what you're running, so the answers are about your protocol, not generic advice.

  • Reads your stack + recent doses + inventory automatically
  • Trained on peptide research — not random Reddit threads
  • Stays in scope — won't pretend to be your doctor
  • Free to try; Pinned Pro unlocks unlimited chats

Library

50+ peptides.
Curated stacks.

Every major peptide, profiled in plain English. Mechanism, typical dose, half-life, recommended timing, and risks — written for humans, not biochemists.

  • Search and filter by goal (healing, muscle, sleep, longevity…)
  • Curated stacks — Wolverine, Cortex, Sleep & Repair, Titan, more
  • Load any stack into Today in one tap
  • "Use this site next" recommendations from real research
