The app
Get the CrestCast app
CrestCast installs from your browser, so there is no app store and nothing to download. It gets its own icon and opens without a browser bar. The steps depend on your device.
Install it on your phone instead
Point your phone camera at the code. It opens this page on your phone, which shows the steps for that phone.

What installing does
It puts an icon on your home screen or desktop that opens CrestCast on its own, like any other app. It is the same account and the same plan as in the browser, so you can add a bill on your phone and read the forecast on a laptop. There is nothing to keep updated.
