Deemed by many to be the “app that makes their watch worth wearing”. Weathergraph is beloved by hikers, runners, bikers, kite surfers, pilots, and many outdoor enthusiasts around the world for its at-glance readability and customizability.

The data refreshes automatically once a connection is available.
All data updates automatically in the background so that Weathergraph always shows the up-to-date forecast instantly.
What people say (in App Store reviews)
... about the Weathergraph
Excellent selection of colors and graphs.
Graphs are the best way of visualizing data and this app uses them brilliantly.
Presenting the weather forecast this way makes so much more sense than anything I’ve seen before.
Both on iPhone and Watch, Weathergraph’s visuals and approach are somehow both simple and comprehensive, offering quick access to all weather information across a useful timeline.
In one complication on my watch, I can easily read see the temperature, “feels like” temperature, humidity, probability of precipitation, precipitation amount and type, atmospheric pressure (or change in pressure) UV index, cloud cover, daylight, wind speed, and direction - for a whole week!
The amount of detail that has gone into creating this app and the amount of customization that is available with this app is amazing.
... about the app developer
Frequent updates and improvements are a plus.
Tomas keeps adding new features and choices for users to tailor their apps to their individual preferences as we didn’t know we needed them. Great stuff! Keep it coming!
Major bonus points to the app developer for actually listening to feedback and incorporating it in a timely manner … kudos!
The app has a freemium model, with a selection of features, themes, and free Yr.no service available to free users without any time limitations.
Weathergraph offers either a yearly subscription (with a 7-day free trial period), or a one-time Weathergraph Forever option to unlock:
- commercial weather sources
- all the features (like wind direction in chart, more chart customizability)
- more watch complications
- and all visual themes for the chart
Privacy and author
The app is made by an independent developer (Tomas here - just write me an email at firstname.lastname@example.org) and cares about user privacy as much as the author does.
I take great care to not know anything about you because this is how I want every other app on my phone to behave as well.
Weathergraph’s servers shield you from the possibility of being tracked by forecast service (as all the requests are stripped of any IP addresses or headers that could identify a specific device) and do not store any locations or personally identifiable data.
Weathergraph also doesn’t serve any ads or use any third-party tracking or analytics library.
