Everything you want to keep track of, nothing you don't.

Made for anyone on a weekly or daily GLP-1 medication, such as semaglutide or tirzepatide. You log what your clinician prescribed. SteadyPen keeps it tidy.

💧

Dose day, always clear

A countdown ring shows when your next dose is due, flags it on the day, and suggests the next injection site so you rotate.

📅

Calendar reminder

Add your dose days to your phone calendar in one tap, with an alert, so you are reminded even when the app is closed.

📉

Weight & measurements

Quick weigh-ins, waist and more, with a trend chart that shows the direction, not just today's number.

🥚

Protein & water

Tap +20 g or +1 glass. Simple daily goals that are easy to forget when your appetite changes.

📝

How you feel

Note nausea, fatigue, heartburn or anything else, with how strong it was. Patterns become easy to see.

Questions

Does SteadyPen tell me what dose to take?

No. SteadyPen is a log. It never recommends doses, changes or treatments. Your clinician decides your plan; you record it.

Which medications does it work with?

Any medication you take on a schedule, weekly, daily or every few days, whether it is a pen, a vial or a tablet. You type the name and dose yourself.

Where is my data stored?

Only in your browser, on your device. We never receive it. Use Backup to save a copy or move it to a new phone.

How do I install it on my phone?

Open the app, then choose "Add to Home Screen" (iPhone: the Share menu in Safari; Android: the browser menu). It opens full screen like any other app.

Is Pro a subscription?

No. One payment, and you get a key that unlocks Pro on your devices. 14-day refund if it is not for you.

Not medical advice. SteadyPen is a personal tracking tool. It does not diagnose, treat or give medical advice. Always follow your clinician's instructions and the prescribing information, and call your local emergency number in an emergency. For adults 18+.
