You can unlock professional Apple Weather, Foreca, Open-Meteo, and Dark Sky forecast sources, weather alerts, nowcast, and all styles and options via a reasonably priced subscription, which covers the cost of data and allows me to further improve Weathergraph.
Weathergraph is offline capable - the app caches the last acquired forecast for up to 24 hours, allowing you to hike or run outside of the network (or go running or biking with a wifi-only Apple Watch) and still see the most recently fetched data.
Weathergraph is a beautiful visual hourly weather widget and forecast for Watch, iPhone, iPad, and Mac, with the Apple Watch app and complications.
If rain or snow is expected during the next 3 hours, you will get a notice on a widget (iPhone, iPad & Mac), a large complication (Watch), and a detailed 3-hour precipitation chart in the app.
Hourly forecast is updated every hour, nowcast and rain alerts update every 15 minutes.
Nowcast and alerts are powered by Foreca and depend on the precision of rain radars in your area.
If you liked Weather Line, Weathertron, or Weather Strip, you might like Weathergraph too :).
Subscriptions made on Apple devices will be charged to your credit card through your iTunes account.
Hikers, runners, bikers, kite surfers, pilots, and many outdoor enthusiasts around the world love the at-glance readability, customizability, and reliability.
One-time Weathergraph Forever unlock is also available.
Your subscription will automatically renew unless canceled at least 24 hours before the end of the current period.
Manage or turn off your subscriptions in App Store app > Account > Subscriptions.
The data refreshes automatically once a connection is available.
You will not be able to cancel once activated.
