Why is this on the App Store?

This app has not been updated in four years and it doesn’t open on my phone. I thought I found a long range weather forecast app…I was wrong. Don’t waste your time.

Not accurate

Used this to help plan a trip and began watching the weather 30 days in advance. Weather forecast went from being sunny in 90s up to 100 then down in the 80s. When we arrived at our destination the highs were in the 60s and 70s with rain.

Sorry for this inconvenience. We have fixed the issue. Please update to the latest version on the App Store.

Worked well, then screen went blank.

Worked well at first then screen went blank. Said it could not find my location and to find it on the map. That’s hard to do when there is no map. Location services are turned on.
