GLP-1 tracker questions, answered.

PenPal is a GLP-1 tracker app for iPhone that logs your shots or pills, injection sites and an estimated medication level, plus meals with protein & fiber, water, weight, steps and side effects. It’s made for adults taking a GLP-1 medicine such as semaglutide, tirzepatide, liraglutide or dulaglutide, and turns what you log into a PDF progress report you can share with your doctor. A penguin pal cheers you on. It’s a tracking tool, not a doctor, a diagnosis or a dosing authority.

29 of them, including English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese and Turkish. PenPal follows the language you use on your iPhone.

On the App Store, for iPhone. Apple shows availability for your region before you download anything.

Yes. PenPal works with semaglutide (Ozempic®, Wegovy®, Rybelsus®), tirzepatide (Mounjaro®, Zepbound®), liraglutide (Saxenda®, Victoza®) and dulaglutide (Trulicity®). Pick your medication, dose and schedule, and PenPal keeps your shot log, reminders and estimated medication level together.

Yes. Choose compounded semaglutide or tirzepatide and log each dose in mg, mcg or units, the way your pharmacy labels it. PenPal keeps your history in one place. It never converts units or calculates a dose.

Yes. Weekly, daily, twice daily or a custom interval all work, and so do pens, vials and tablets like Rybelsus®. Log each dose in mg, mcg or units, exactly the way your label reads. Here’s what to record for a daily GLP-1 pill.

The medication, the amount, the time and the injection site, plus a note when something is worth remembering. Enter the dose exactly as it appears on your prescription label or care plan. PenPal never tells you which dose to take or when to change it. Our guides to a semaglutide injection log and a tirzepatide injection log go further.

Yes. Turn on dose reminders and you’ll get a heads-up a few hours before each dose, for every medication you track. PenPal also counts down to your next shot, so shot day never sneaks up on you.

Yes. A body map remembers where each shot went and suggests where to go next, so rotating sites takes zero brainpower. Always follow the injection instructions that came with your medication. Our site rotation log guide shows what to write down.

That’s one for your prescriber or pharmacist, not an app. The right move depends on your medication and how much time has passed, so check the instructions that came with your prescription. In PenPal, log what actually happened and jot the question down for your next appointment. Our medication tracker guide shows how to note a late or missed dose.

PenPal combines the doses and times you log with published absorption and half-life values for your medication to draw an estimated level curve. It’s a picture of how your logged doses stack up over the week. It isn’t a lab measurement, and it’s never a reason to change your dose. Here’s how the estimate is drawn.

No. The level curve is an estimate built from the doses you log and published values for your medication. It isn’t a lab result or a measurement of the medicine in your body, and it’s never a reason to repeat, delay or change a dose. Treatment decisions belong with your clinician.

Snap a photo of your plate or describe it in a few words. PenPal’s AI estimates calories, protein, fiber and macros, then scores the meal. Estimates can be off, so you can edit anything it gets wrong. It’s there to make logging easier, not to prescribe a diet. No scale handy? Here’s how to log meals without a food scale.

Yes, if you turn it on. PenPal can bring in steps, workouts, active energy, weight and water from Apple Health, so there’s less to type. Your Apple Health data stays on your iPhone and isn’t uploaded to PenPal’s servers. Here’s what moves in and out of Apple Health.

Log nausea, fatigue, reflux and friends in seconds, along with how strong they felt. Over time you’ll see your own patterns, which makes for a clearer chat with your clinician. See what to write in a side effect diary. PenPal doesn’t decide whether a symptom is a side effect, so if something feels severe or worrying, contact a healthcare professional.

Yes. Create a PDF progress report for the dates you choose, with your doses, weight, side effects, nutrition, water and activity. You decide whether to share it, and with whom. Our guide shows how to make a progress report for your doctor.

Little celebrations for firsts, streaks and milestones, from your very first shot to a million steps. There’s always one more to unlock, and your pal notices every one.

It lives on your Today screen and reacts to what you log: a meal, a dose, a glass of water, a weigh-in. You give it a name, and its hearts stay full while you keep showing up. It never scolds you. On a quiet day it simply waits for you.

Every day you log something yourself (a meal, water, your weight, a side effect, a dose or a workout you add), your streak grows. Steps and other data synced from Apple Health don’t count on their own. Miss a day and the streak freezes instead of breaking; log again and it thaws.

Yes. The small streak widget shows your flame, your streak count and a penguin scene that changes with the time of day and with how your streak is doing. Add it from your Home Screen like any other widget.

Pebbles are earned, never sold: your daily and weekly goals pay them out. Spend them in the shop on hats, glasses, outfits and backgrounds for your penguin.

Yes. We never sell your health data or use it for advertising. Apple Health data stays on your device, and you can delete your account from inside the app whenever you like.

No. PenPal is a tracking companion, not medical advice. It doesn’t diagnose, prescribe or adjust doses. Follow your prescription and care plan, and talk to your clinician about treatment questions or any symptoms that worry you.
