GLP-1 tracker · iOS & Android

Personalized GLP-1 tracking, made simple.

Pepta is the privacy-first tracker built for users on GLP-1 medications — weekly or daily injections (Mounjaro, Zepbound, Wegovy, Ozempic, Trulicity, Saxenda, Victoza) and oral semaglutide (Rybelsus). Log doses, watch your weight trend, rotate injection sites, and share a clean PDF with your clinician — all on your device.

Who it’s for

Wherever you are in the journey.

Just starting out

First pen in the fridge, lots of questions. Pepta keeps your schedule, sites, and starting weight in one calm place.

Titrating up

Moving 2.5 → 5 → 7.5 mg? Dose-colored charts show exactly how each step changes your trend.

Managing side effects

Log nausea, fatigue, or injection-site notes and spot the patterns between doses — ready to discuss with your clinician.

In it for the data

Estimated levels, trend lines, streaks, and exports. If you love a good chart, this is your tracker.

Track your GLP-1 journey with confidence

Pepta gives you the tools to understand your medication, watch your progress, and have better conversations with your doctor.

Premium feature

Beautiful, detailed charts that tell your story

Pepta's interactive weight-trend chart paints the full picture of your journey — color-coded by dose, with estimated medication levels, side effects, and weight overlaid on a single timeline. Zoom in on a week, pan across a year. The patterns are right there.

See trends in weight, doses, and side effects in one view
Track estimated medication levels through your week
Export a clean PDF summary for your healthcare provider

Never miss a dose

Customize when you want to be reminded — Pepta sends a quiet ping when your next shot is due, then logs it in two taps. A streak grid shows your weeks at 100% on time.

Never run out

Pepta auto-decrements doses from your pen, warns you before it runs dry, and the body-map rotates injection sites so no spot gets used twice in a row. Your skin will thank you.

Share with your clinician

Export a one-tap PDF with your dose history, weights, and side-effect log — formatted clean enough to print, share via Messages, email, or AirDrop. Built on-device, never uploaded.

Built for breadth

Works with every major GLP-1

Whether you're on Ozempic^® (semaglutide), Wegovy^®, Mounjaro^® (tirzepatide), Zepbound^®, Rybelsus^®, Trulicity^®, or an investigational triple-agonist like Retatrutide, Pepta adapts the tracking experience to your medication automatically. Daily, weekly, or custom — the cadence is yours.

Privacy

Your health data is nobody’s business.

Most health apps are data businesses with an app attached. Pepta is the opposite: everything you log lives on your phone and nowhere else. There is no Pepta cloud to breach, no profile to sell, and no account to hack.

No account, ever

No email. No phone number. No sign-in screen. Open the app and start logging — we never learn who you are.

On-device by default

Doses, weights, and notes are stored in your phone’s local storage. They never touch a Pepta server — we don’t have one.

No ads. No trackers.

Zero ad SDKs, zero data brokers, zero analytics that can identify you. Your data is never sold — there’s nothing to sell.

Yours to take or erase

Export your entire history as JSON or a clinician PDF anytime. Delete everything with one tap — it’s gone for good, because only you ever had it.

Loved by people on a GLP-1 journey

Real notes from early Pepta users.

★★★★★

The dose color bands on the weight chart finally made my titration story click. I can see exactly when 5 mg stalled and 7.5 mg started working.

★★★★★

Pen tracking is the killer feature for me. I always forgot when I was running low — now Pepta tells me three days before my pen is empty.

★★★★★

Site rotation tracker is brilliant. My old method was a sticky note on the fridge. The body-map view on Pepta is so much better.

★★★★★

I love that nothing leaves my phone. No login, no cloud account I have to trust. It just works, and it's mine.

★★★★★

Sent the clinician PDF to my endocrinologist before my appointment and she said it was the cleanest summary she'd seen from a patient app. Gold star.

★★★★★

The reminder banner is gentle, the streak grid is motivating, and I haven't missed a dose since I installed it. Five weeks in.

Frequently asked questions

What is Pepta?

Pepta is a privacy-first GLP-1 tracker for users of medications like Tirzepatide (Mounjaro^®, Zepbound^®), Semaglutide (Ozempic^®, Wegovy^®, Rybelsus^®), Dulaglutide (Trulicity^®), and investigational peptides like Retatrutide. Log weekly or daily doses, rotate injection sites, watch your weight trend, and export a clean PDF for your clinician — all without an account.

Is Pepta free?

Yes — the core tracker is free forever. Logging doses, weight check-ins, reminders, body-map site rotation, pen tracking, the daily check-in, the weight-trend chart with dose-strength color bands, and the streak grid are all included on the Free tier with no time limit and no account required.

Pepta+ is an optional subscription that unlocks the deeper estimated-medication-level chart (a live PK estimate from every dose you log), shot-planning preview before your next injection, unlimited medications (Free is capped at two), the PubMed study library, polished clinician-ready PDF exports, and the goal-ETA forecast. Free users see exactly which controls are Plus (small lock icon) and never lose access to the Free features they already use.

What does Pepta+ include?

Pepta+ adds: estimated medication-level curves built from every dose you log, shot-planning preview that shows the curve before your next injection, unlimited medications (Free is capped at two active drugs), the PubMed study library with plain-English summaries of FDA and peer-reviewed sources, polished clinician-ready PDF exports, 90-day + all-time chart ranges, and the goal-ETA forecast on the weight chart. Pricing is $9.99/month or $39.99/year with a one-week free trial. Everything in Free stays free — Pepta+ is purely additive.

Which GLP-1 medications does Pepta support?

Pepta supports every major GLP-1 — Ozempic^®, Wegovy^®, Mounjaro^®, Zepbound^®, Rybelsus^®, Trulicity^® — plus dual and triple agonists like Retatrutide. The cadence (daily, weekly, or custom) and dose units adjust to match your medication automatically.

Where is my data stored?

On your device. Pepta is on-device by default — no account, no cloud, no analytics that can identify you. You can export your full data set as JSON whenever you want, and import it back to a new device. We never sell your information; there is no information to sell.

Can Pepta remind me when to take my dose?

Yes. Pepta sends a quiet local notification on your schedule — daily, weekly, or custom — and shows a countdown ring on the home screen so you always know what's next. Reminders work fully offline.

Does Pepta track injection-site rotation?

Yes. Pepta tracks every site you've used and ranks them so you (and the app) always know which spot is up next. Helps prevent skin irritation and keeps absorption consistent.

Can I export a report for my doctor?

Yes. One tap exports a clean PDF — your dose history, recent weights, medications, and any notes — generated entirely on-device and ready to share via Messages, Mail, AirDrop, or Files. No email upload required.

Is Pepta a medical device?

No. Pepta is an educational tracking tool, not a medical device. Always follow the guidance of your licensed healthcare provider for dosing, side effects, and treatment decisions.
