Severe weather, before it happens.
You shouldn't find out about a storm when the first bolt hits. Before It Strikes watches the sky for you — pushing official National Weather Service warnings the instant they're issued, tracking storms headed your way, and counting down exactly when it's safe to go back outside.
Free. Nationwide. Built for anyone who has to make the call to head inside.
-Lightning safety countdown
When lightning strikes within 10 miles, a 30-minute timer starts — and resets with every nearby strike, just like the 30-30 rule the pros use. When it reaches zero, you're clear. It lives right on your Lock Screen and Apple Watch.
-Official NWS alerts, instantly
Tornado, severe thunderstorm, and flash-flood warnings straight from the National Weather Service — for home, the lake house, the kids' school, anywhere you save. With a live expiration countdown, plain-English guidance, and every affected county.
- Hi-res 3D radar
Crisp, smooth radar you can tilt into 3D and zoom to your own street. 150+ live radar sites, nationwide — pan to any storm in the country.
- Storm Center
One screen that reads the sky: a 1–5 threat level, live lightning rate, the nearest strike, the next-6-hour outlook, and local storm reports as they land.
- See it coming
A heads-up when a storm is overhead or heading your way — with tornado, wind, and hail threats in plain words, before the first bolt.
- On your wrist
The all-clear countdown mirrors to your Apple Watch as a glowing ring — a glance tells you whether it's safe to go back out.
- Follows you
Save every place you care about, or let it track wherever you are. Loud when it counts, silent when it doesn't.
No subscription. No paywall on safety. Every feature, free.
A note on safety
Official National Weather Service warnings are always the source of truth. Some features — such as lightning prediction and storm scoring — are experimental situational awareness and should never be used in place of official warnings or lightning-safety guidance. When in doubt, seek shelter.
Easy to use, straightforward, and thoughtfully designed. Everything is simple to navigate, and the layout makes it easy to find the information you need. I was especially impressed with its accuracy. It gave us timely lightning alerts, allowing us to warn our coaches to stay on alert and prioritize safety. A great app for anyone who needs reliable weather awareness. Highly recommend
Easy to read, enjoyable to look at, and has been really accurate so far!

Very easy to use and to understand, the design is really clean and unlike other weather apps I’ve used, and it gives just the right about of information needed to keep you informed. Looking forward to using this app as all the storms come in.
Great for athletic trainers!

Being an athletic trainer who is responsible for the safety and wellbeing of athletes and coaches, this app is great! It does a great job notifying me of potential & incoming storms and lightning strikes so I can plan ahead and get my athletes to safety. Great job so far with the app!
All Clear Outlook (for Precision users)
When you are sheltering from lightning, you now see the chance that your shelter ends when the countdown reaches zero. For example: "55% chance the shelter ends at 11:39 AM." Tap it to see why, and what happens if lightning strikes within 8 miles again. The clock resets, and it is usually another hour or so before the shelter lifts.
The outlook comes from our research on thousands of real storms across the country. It helps you decide whether to wait it out or change your plans. The 30-minute countdown and official safety guidance still decide when it is safe to go back outside.
Also in this version: performance improvements and fixes.
