We don't currently have an app but you can save Flint to your home screen.
If you're using an iOS or Android device, you can add the web-app bookmark to your home screen where it will look just like an app.
To add Flint to your home screen on:
Open Safari and go to the Flint login page.
Select the Share icon (the square with an arrow pointing up).
Select ‘Add to Home Screen’. The app will now be added to your home screen.
Open your browser and go to the Flint login page.
Select the Settings button (the three vertical dots).
Select the star symbol—you can edit the page name, and choose a folder to save it to.
Go back to the browser settings menu, and open the Bookmarks folder.
Select the Flint bookmark, and select 'Add to Home Screen' from the list of options.
