What Our Users Are Saying

Makes hiking easier!!!

"This app has helped me when I decide to hike last minute!!! Out west the weather changes constantly so it’s notified me when I should turn back or not!"

Great Design

"I really love this App. It’s simple, clean and just does a great job at predicting lightning conditions without a lot of the extra bells and whistles that so many Apps are cluttered with. I don’t know how it works but it sure does!"

Love the app

"So helpful with kids games and practice. I also use it for work all the time."

Wow, so cool!

"I’m not outdoorsy, but I can see many uses for this re: outdoor activities. Swimming, boating, golf. I think it would be great for campers, kids sports, etc."

My new preferred App!

"I work year round for a summer camp, and being that Nebraska weather can vary so widely, we always had to pull kids inside due to fear of inclement weather. This app makes it clear and concise for us to watch out for the safety of our campers! Love it. 5 stars."

People definitely need this!

"When I first installed it, it showed me what the closest lightning strike was. This app was helpful when I was caught in a thunderstorm. Now today, the app updated and it shows the rain in the radar. The app should be Installed in more devices!"

Highly recommend the app

"Used Flash last Sunday and it was right on. While the CNY weather app had a forecast for thunderstorms for our area, Flash had the lightning pinpointed to the house. The forecast tab is a great addition and pegged lightning relief very well. Highly recommend the app."

Highly recommend the app

"So I live in the Midwest, and we have our regular series of thunderstorms. This tool is very effective in letting you know when you should be indoors, and about the intensity and duration of storms. Highly recommend."

My favorite app

"Flash AI Lightning Detection is my favorite app on my phone. I use it all the time."

Simple, informative interface

"Simple, informative interface. Options for distance warnings. Says it provides NO data to 3rd parties, which almost seems to good to be true these days."
