Health & Fitness, Medical
A protocol, organised and kept private.
PepTrack is a local-first organiser for people already running peptide routines. Dose logging, a schedule with reminders, a reconstitution calculator and an activity estimator, all stored on the device rather than on someone else's server.
The problem
Spreadsheets and notes apps, holding sensitive data
People running a protocol were tracking it in whatever was nearest: a notes app, a spreadsheet, a group chat. That works until the schedule gets complicated, and it never handles the arithmetic.
It also means health data sitting in whichever cloud that tool syncs to, which is a poor trade for something this personal.
What we built
The parts that mattered.
Dose logging in one tap
Log a dose for a saved compound and see the full history, so consistency is visible rather than remembered.
Schedule and local reminders
A calendar view of the routine with reminders that fire before each dose, handled on device.
Reconstitution calculator
Vial size, peptide amount and BAC water in, concentration and U-100 draw estimate out. The arithmetic nobody wants to do at 7am.
Activity estimator
Estimated half-life and activity timing for logged compounds, so the next dose is a decision rather than a guess.
Local-first storage
Routines, logs, schedules and notes stay on the device. Privacy is an architecture choice here, not a policy paragraph.
See for yourself
The fastest way to judge the work is to use it.
Result
Live on the App Store, rated 4.6.
I've used a few peptide calculators and apps before that were mostly clunky and confusing, but after using PepTrack it made things more easy and simple. Would recommend.
