Ratings and reviews

So, I used to love this app. It worked very well up until the latest OS update. I emailed the developer to advise them of the issue and it is apparently a known issue with no timeline for a fix. The issue, if you try to share a clip it crashes. Also, seem to have layer issues with boxes appearing around the map and effecting the graphic animations. Would love to make it 5 stars...

This last update really F-ed up the Android widget. It got particularly bad after updating to Android 15. Can't seem to get it to look right, like have two graphs in the widget at the same time, or any graph other than the Everyday graph. And it always looks either squished or stretched. Sad.

Tons of information. Highly configurable. I've been using this for 3 years & it's by far the best weather app. CON: A new white bar has appeared across the bottom of the display for some reason which isn't present on an earlier version on a different phone. A shame because it downgrades an otherwise attractive full image.

What’s new

Release 4.102 (18 Jun 2025)
========================

EXCITING!! We have a new data source, the HARMONIE 5km weather model which extends from Europe, across the UK to Iceland.

Also added the ability to add air quality, wave and marine gauges.

Travel Mode now updates your location if the GPS change is over 500m.

Widgets, which is on going pain, got several bug fixes.
