User reviews

Incredible accuracy

There’s not an app that is as accurate as Flash Weather… I have tracked severe weather using multiple apps to compare accuracy and Flash wins every time!

Dog thunder flight risk

Highly recommend. Been super useful to get alerts when lightning and thunder are close by. We have a dog that is terrified of thunder and jumps the fence. Now we can prepare and lock her in the house.

Pay for too much

Tried this app when first came out. Had issues, something’s changed. But way too many features are free on well known free apps. Paying for lightning alerts-nope, the metrics (showing humidity, uv, etc) never appears).
Will stick with major names and forget all this AI BS.

Great app IF you pay.

Great lightning app and interface, but basic things like more than one location notification requires a subscription so I’ve moved to other apps.

Issues

This app was recommended to me with the caveat that it doesn’t always load quickly or at all. After a few days I would agree. I’m in the middle of a storm and the lightening feature won’t load. Seems decent but only if it works which appears to be about half the time. Certainly not worth the price they charge

Response from developer

Hi Rule, thanks for the feedback and sorry the lightning feature let you down when you needed it most. That's not the experience we want, especially during a storm. Mind emailing support@flashweather.ai with your device and any screenshots you're able to share? We'd like to look into what's causing the load issue.
