How it works
Built around your injection week.
If you inject once a week, your week has a shape. The app follows it, one day at a time.
- D1
- D2
- D3
- D4
- D5
- D6
- D7
Day 1
Injection day. Log your dose and where you injected.
Days 2 to 4
A short briefing each day, written for where you are in your week.
Days 5 to 7
A reminder when your next dose is due, and the week starts again.
Log how you're feeling on any day, in a few taps. Taking a daily tablet instead? The app follows that too.
In the app
Real screens, not mock-ups.
These are taken from the app itself, the same screens you'll see in the App Store.
Understand your eating.
The week's meals at a glance, with optional daily targets you set yourself.
Read up, in plain English.
Short guides on side effects, food, your injection routine, movement and wellbeing, reviewed by clinicians.
Log it in seconds.
Taps, not paragraphs. You can log:
- Your doses and where you injected
- How you're feeling, with optional severity
- Your weight
- Meals and activity
- Apple Health or Health Connect, if you choose to connect them
If you're working with a pharmacy or clinic, what you log can be shared with them.

Your data
Who sees what you log.

What is nudge?
A free companion app for adults on GLP‑1 medication, such as Mounjaro or Wegovy. It gives you short daily information timed to your treatment week, a simple place to log how you feel, and honest answers to common questions.
Is it free?
Yes. No subscription, no in-app purchases, no adverts.
Who is it for?
Adults aged 18 and over who have been prescribed a GLP‑1 medicine by a UK healthcare professional. You don't need to upload your prescription, but everything in the app is built around being on treatment.
Which medicines does it support?
Mounjaro (tirzepatide), and Wegovy (semaglutide) as a weekly injection or a daily tablet.
Do I need to download it?
You can download it free from the App Store or Google Play, or use it in your browser at app.nudgemed.app. It's the same account either way.
How do I sign in?
With your email address. We send you a sign-in link, so there's no password to remember.
Is it a medical device?
Yes. It's registered with the MHRA as a Class I medical device. It gives information and behaviour support; it doesn't give medical advice, diagnose, or recommend or change your dose. See the regulatory details.
Can I delete my data?
Yes. You can download your data or delete your account from Settings in the app at any time.
What if something feels wrong?
Contact your prescriber or call NHS 111. In an emergency, call 999. You can also report a suspected side effect to the MHRA through the Yellow Card scheme.
