GLP-1 tracking for iPhone

The GLP-1 medication tracker for your everyday routine.

PenPal helps you keep a clear record of injections, reminders, nutrition, symptoms, weight, and progress while you follow the plan provided by your healthcare professional.

Free to download. Optional features are available in the app.

What PenPal does

A clearer record of the routine you already follow.

A tracker cannot replace a prescriber or measure what is happening inside your body. It can make your own notes easier to keep, review, and discuss.

Medication log

Record medication, dose details as prescribed, date, time, and notes so your history stays in one place.

Medication timeline

View an estimate based on your logged injections. It is a visual aid, not a blood-level measurement or dosing instruction.

Nutrition notes

Use text or a food photo to create an AI-assisted estimate, then review it as you track protein, fiber, calories, and hydration.

Progress reports

Follow weight and symptom trends over time and export a report you can choose to discuss with your healthcare professional.

Built for useful conversations

What can you track with a GLP-1 app?

A practical log usually brings together the details that are easy to forget between appointments: when you took a dose, how you felt, what you ate, how much water you drank, and how your weight changed.

PenPal is designed to organize those observations. The goal is a more useful personal record—not a diagnosis, prescription, or promise of a particular weight-loss result.

A simple weekly record

  • 01Log the medication and injection details shown on your prescription label.
  • 02Note symptoms, meals, hydration, movement, or questions for your next visit.
  • 03Review trends without changing treatment based on an app estimate.
  • 04Share a report only when you choose and with the person you choose.

Important scope

Is PenPal medical advice?

No. PenPal is a tracking and wellness companion. It does not diagnose, prescribe, adjust doses, or replace a licensed healthcare professional. Follow your medication label and care plan, and contact a clinician for treatment questions or concerning symptoms.

For general background on prescription medicines for weight management, see NIDDK’s overview. For medication-specific instructions, use the patient information supplied with your prescription; MedlinePlus’ tirzepatide information is one official reference.

Make your next check-in easier to prepare for.
