Pepta reminder notification: time for your dose

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.

Pepta pens & vials screen with site rotation rankings

Track every pen & site

Pepta auto-decrements doses from your pen, warns you before it runs dry, and tracks injection-site rotation so no spot gets used twice in a row. Your skin will thank you.

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.

Lisa K. Mounjaro
★★★★★

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.

Jordan B. Zepbound
★★★★★

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.

Priya S. Wegovy
★★★★★

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

Alex T. Ozempic
★★★★★

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.

Sam D. Tirzepatide
★★★★★

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. All core tracking is free — doses, weight, reminders, site rotation, the weight-trend chart, and the clinician PDF. Optional premium features can be added later for power users.

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.
