User reviews

An ok app

Could be a lot better. The data readings for your hardware sometimes get screwy and cannot be corrected which then makes the historical charts hard to read.

I like the app

I like the app I just wish the rain numbers were bigger instead of the rain icon. I would like to see the rain numbers bigger especially since is live and also the live wind speed make it larger. We want to see the live content bigger.

Watch Complication is Broken

Since upgrading to iOS27, I can no longer display the weather on my watch. It does not show in the list as an option and deleting the app and reinstalling did not resolve the issue.

Feature request

Still loving my Tempest. Could you add a graph view of the stats you’re already tracking, like barometric pressure, humidity, etc? And if possible could the widgets show some of these other stats? Also tapping the widget to open the app seems to always crash/hang the first time since ios26.

Worked for 10 hours

I guess I have to use the online version!? The app worked for about 10 hours and now is stuck in a loop of telling me my station is locked to another account, but works fine online so I assume the app has some problems.
