Download the Jane's Weather app
Available in the App Store and on Google Play
If you already have a subscription from janesweather.com you can use that to log in to the app.
Otherwise sign up through the app and access all platforms with the one login.
I'd recommend purchasing a paid subscription through janesweather.com for apple as it is 30% cheaper than directly in the app store. Android has no fees and you can purchase a subscription easily within the app.
