Mobile App

We are delighted to give healthcare workers access to our ‘MySirenum’ mobile app.
From now on, you can use it to let us know your availability for work,
respond to job offers, view your bookings and enter details of shifts worked.
All from the convenience of your mobile device.

Getting Started

To get started:

  • Open this webpage on your mobile and tap the relevant icon to the right or search for “MySirenum” in the app store and install it.
  • When it’s installed, tap on the “MySirenum” icon to open it.
  • Select ‘yes’ if you’re asked to confirm if you would like notifications.
  • Tap on the “Sign up” button, enter the email address you’ve registered with us and create a password of your choice to complete your registration (don’t forget to use a password that only you know and never share it with anyone).

Then simply sign in (using your email address and password) and follow the onscreen instructions.
