Peptide tracker iOS + Android

A cleaner way to track your peptide protocol.

PepMod is a private tracker for iPhone and Android. Build your protocol, log each entry, get reminders and see your adherence over time. It keeps the record you give it; it doesn’t tell you what to take.

What PepMod does

Your protocol, your log, one place.

Most people start with a notes app or a spreadsheet. PepMod replaces both with a schedule that reminds you, a log you can correct and charts that show how consistent you’ve been.

SYS.PROTOCOL // TODAY

Know what’s due today, and log it as you go.

The Today screen lists every entry scheduled from your active protocols with its time, plus your adherence for the day. Mark an entry taken or skipped, or undo it, and add the actual time, site or a note if you want the detail.

  • Taken, skipped and undo on every entry
  • Optional time, site and notes per log
  • Adherence for the day at the top

SYS.PROTOCOL // WEEK

See the next seven days of your saved protocol.

The weekly planner lays out each day of the week from the schedule you set up: daily, every other day, twice weekly, weekly or as needed. It is a calendar of your own plan, nothing more.

  • Day-by-day view of what you scheduled
  • Daily, every-other-day, twice-weekly, weekly or as-needed
  • States plainly that it doesn’t give dosing advice

DOSE.HISTORY // 30.DAY

A 30-day record you can actually correct.

Every log lands in your dose history. Tap a record to fix its amount, actual time, site, notes or status, or add an entry you forgot with Log previous dose, so the record matches what really happened.

  • 30 days of logged entries
  • Edit any record after the fact
  • Log a previous entry you missed

Free tool // runs in your browser

Free peptide calculator for the unit maths.

Convert mg to mcg exactly, work out a solution’s concentration from its total mass and final volume, and find the volume that holds an amount, or the reverse. Every step is shown, nothing you type is stored, and it never suggests an amount.

Readout // example arithmetic

  1. 10 mg × 1,000 = 10,000 mcg total
  2. 10,000 mcg ÷ 5 mL = 2,000 mcg/mL
  3. 2,000 mcg/mL ÷ 1,000 = 2 mg/mL
  4. 250 mcg ÷ 2,000 mcg/mL = 0.125 mL
Hypothetical round numbers to show the arithmetic. Not a dose.

How it’s built

Records, not recommendations.

It keeps your record

PepMod stores the protocol, amounts and times you enter. It doesn’t recommend peptides, amounts, cycles or protocols, and it isn’t medical advice.

Your account, your data

Protocols, logs and body metrics are saved to your own account (sign in with Apple or email) and only your account can read them. Details are in the privacy policy.

Same app on both phones

One design on iPhone and Android, so switching phones doesn’t mean learning a new app.
