PepSync: Peptide Calculator

Peptide Calculator & Logger

Free · In‑App Purchases

One clear answer for every reconstitution — draw-to units, live vial counts, and schedules you author. One-time purchase. No subscription, no account, no cloud. Know exactly what to draw. PepSync turns the numbers on your vial label amount, water, syringe into one clear answer: the units to draw to. Then it keeps the books: what's left in every vial, when each one should be discarded, and the schedule you built for yourself. No spreadsheet. No napkin math. No squinting at tick marks. ALL-NEW IN 2.0 Version 2 is a complete redesign a ground-up UI overhaul built around one idea: the answer comes first. A cleaner dark interface, a streamlined four-tab layout with a quick-add button always under your thumb, and every number you'd act on rendered in crisp monospace. Faster to read at 7 AM, faster to log, easier to trust. THE CALCULATOR - Answer-first: the draw-to units stay pinned while you adjust inputs - Clean-mark check: if your numbers land between syringe marks, PepSync suggests the water amount that fixes it - Show Math: every step of the calculation in plain English — verify anything - Blend support: multi-component vials with per-draw breakdowns - Reverse calc, water calc, unit converter (mcg / mg / mL / IU / units), and titration tools VIALS THAT COUNT THEMSELVES - Log an entry and the vial's remaining count ticks down automatically - Discard countdown runs from your reconstitution date - Projected-empty date tells you in advance whether you'll finish a vial before its discard day - Multiple vials of the same compound? One wears the "in use" badge logging just works - Optional cost tracking per vial SCHEDULES YOU AUTHOR - Build simple daily plans or staged ones — step changes, on/off phases, multiple compounds — entirely from your own entries - "Up next" shows what you scheduled, when, with your rotation site - Missed an entry? It's recorded honestly. Plans never shift and never double up - Optional reminders that respect your privacy: lock-screen text is discreet by default YOURS ALONE - Local-first by architecture: no account, no server, no analytics, no cloud copy - Your data lives in a database on your iPhone — the only way it leaves is you tapping Export - Full backup and restore: one file, readable, yours - Filterable history with CSV export ONE-TIME PURCHASE Pay once, own it. No subscription. Restore anytime on your Apple ID. PepSync is a calculation and record-keeping utility.
