# A private GLP-1 tracker for Mounjaro, Ozempic, Wegovy and Zepbound. Know where you are in your dose cycle, not just when you last injected. Penwise tracks every shot, your weight and how your body responds, and all of it stays on your phone: no account, no server, nothing to leak. Free core tracker, forever. 14-day Penwise+ trial, no card needed. - **Download on the App Store:** https://apps.apple.com/app/id6787772423 - **Get it on Google Play:** https://play.google.com/store/apps/details?id=sk.v2.apps.penwise - **4**: medications modelled, from semaglutide to retatrutide - **17**: pens recognised, plus five vial presets - **2**: watch platforms included at no extra cost - **0**: servers holding your health data ## Every GLP-1 you are likely to be on. Penwise knows the pen, the dose ladder and the way the medication actually behaves between shots. Pick yours to see what that means in practice. - [Mounjaro](https://penwiseapp.com/en/guides/mounjaro-tracker) (tirzepatide): KwikPen and single-use pen, 2.5 mg to 15 mg, weekly. Sixty clicks to a full dose, thirty days once started. - [Ozempic](https://penwiseapp.com/en/guides/ozempic-tracker) (semaglutide): All four dial pens, 0.25 mg to 2 mg, weekly. Penwise knows why the same 0.25 mg is a different number of clicks on each. - [Wegovy](https://penwiseapp.com/en/guides/wegovy-tracker) (semaglutide): Single-dose pen and the four-dose FlexTouch, 0.25 mg to 2.4 mg, weekly, with the full sixteen-week titration mapped out. - [Zepbound](https://penwiseapp.com/en/guides/zepbound-tracker) (tirzepatide): KwikPen and single-use pen, same six strengths as Mounjaro, tracked against a weight-loss goal rather than an HbA1c. - [Saxenda and Victoza](https://penwiseapp.com/en/guides/saxenda-tracker) (liraglutide): Daily rather than weekly, which changes everything about reminders, site rotation and how fast the level moves. - [Rybelsus](https://penwiseapp.com/en/guides/rybelsus-tracker) (oral semaglutide): A tablet, so no site and no pain to record. Penwise hides the fields that do not apply and tracks the fasting window instead. ## Your health data never leaves your phone. This is not a policy we could quietly change. There is no Penwise server for health data, so there is nothing for us to hand over, sell or lose. - **No account**: No email, no password, no sign-up. The app works the moment you install it. - **No servers**: Every dose, weight and symptom stays in the app on your device. We never receive it. - **No third-party tracking**: No ad networks, no third-party analytics, and no health data off your phone. If a creator referred you, we receive their code and a random install id, and nothing else. - **Your export, your keys**: Backups are encrypted on your device with a passphrase only you hold. We hold no keys. ## Built for how GLP-1 treatment actually goes. - **An estimated level, not just a date**: A log tells you when you last injected. Penwise models how much medication is in your system right now, using real absorption and elimination half-lives for semaglutide, tirzepatide, retatrutide and liraglutide. It is the difference between “my last shot was Tuesday” and “I am on the downslope, which is why the food noise is back”. - **Patterns you would never spot alone**: Which injection site actually hurts less for you. Which day after a shot the nausea tends to land. Whether you are drifting late on your doses. Penwise only says something when it has enough of your own history to be right, so it stays quiet rather than inventing a pattern from three data points. - **Progress worth sharing**: A built-in studio turns your milestones into something that looks designed rather than screenshotted. Pick a subject, a layout and a palette, add your own photo and headline, and hand it straight to Instagram, WhatsApp or your camera roll. [See everything Penwise does](https://penwiseapp.com/en/features) ## Free, forever The core tracker is meant to stay genuinely useful without ever paying, including getting your own data back out. - Log injections: date, time, medication, dose, site, pain and notes - Log oral doses as well as injections - Track your weight and see your trend - Rotate injection sites on a body map, with the least recently used one suggested - Full history and a calendar of everything that happened on any day - Log cravings, appetite and day notes - Dose reminders - Export everything as CSV or JSON, with no paywall on your own history ## Penwise+ Everything above, plus the parts that turn a log into an understanding of your treatment. - Estimated medication-level curves - The full Insights tab: trends, correlations and observations - Nutrition and protein tracking - Apple Health and Health Connect sync - Doctor-ready PDF reports and a clinical-standard export - Import from Shotsy - The share card studio - Colour themes, light and dark, AMOLED black [See pricing](https://penwiseapp.com/en/pricing) ## On your wrist, on both platforms. Apple Watch and Wear OS apps are included at no extra cost. Most trackers in this category have neither. - Your next dose, your streak and your medication at a glance - Log a shot from the wrist; it syncs the moment your phone is back in range - Measure your resting heart rate after a shot and save it onto that shot - Watch face complications on both platforms, and a tile on Wear OS - The watch follows the colour and language you chose on your phone ## Coming from Shotsy? Import your export, CSV or backup, in a couple of taps. Shots, weights, sites and side effects all come across, importing the same file twice never duplicates anything, and the whole import can be rolled back if you change your mind. 1. **Export from Shotsy**: Settings, then Manage My Data, then Export Data. JSON if your version offers it, CSV if it does not. 2. **Open it in Penwise**: The in-app walkthrough names the exact path and picks the file up from wherever you saved it. 3. **Check it, then keep it**: Penwise previews what it found before writing anything, and the whole import rolls back if you change your mind. [More on switching](https://penwiseapp.com/en/faq) ## The parts of GLP-1 treatment nobody explains. How long the medication actually lasts, why a missed dose matters more on tirzepatide than on semaglutide, what a click on your pen is worth, and how long a pen stays good once you start it. Written plainly, with the numbers shown. [Open the guides](https://penwiseapp.com/en/guides)
