4Warning is a community safety app. People nearby report what they see — theft, hazards, trouble — so you know before you reach it.
Community awareness, not fear. When people share what they see, everyone nearby gets the chance to make a better decision.
On your route, minutes before you reach it, somebody has already seen what you are walking into.
A few taps to post a warning. Nothing to gain, no followers needed — it just helps whoever is behind.
Warnings come from users who are actually there, not a newsfeed hours behind the event.
No subscription and no tiers. Download it and you are part of the community.
Five steps. No sign-up wall, no waiting for the news to catch up — just people telling the people behind them what is ahead.
A user sees something others should know about. A phone snatcher working a junction, a car being broken into, a hazard in the road — the kind of thing that stops with you unless there is a simple way to pass it on.
Create a warning through 4Warning. Choose what you saw and where it happened. It takes seconds, and you do not need followers or a long description for it to be useful to somebody walking that way.
The warning becomes available to relevant users nearby. Not broadcast to the whole country and not buried in a feed — it goes to the people whose route is about to take them past the thing you just reported.
Your half-mile radius moves with your current location. Walk, drive or cycle and the circle travels with you, so what counts as relevant keeps updating against where you actually are right now.
When you move within approximately half a mile of a relevant warning, 4Warning may alert you. Before you reach it, while there is still time to change direction, avoid the area, or simply be more aware.
Free on iPhone and Android.
Information can travel around the globe in seconds, yet we can still be unaware of something happening a few streets away.
News and social media were never built to tell you what is happening on the road you are about to walk down. 4Warning is.
Community awareness helps people make better decisions about what is around them — whether that means changing direction, avoiding an area, or simply paying more attention. These are the kinds of things users report.

Examples of the kind of alert 4Warning delivers. Real warnings come from users near you, in the moment.
Two riders working the pavement near the station entrance, taking phones out of people's hands as they pass. Keep yours out of sight until you are through the underpass and back onto the main road.
Three cars on the upper deck with their windows gone in the last hour. If you are parking here tonight, take everything off the seats — they are going for bags and anything left in plain view.
Water right across both lanes and the pavement is flooded on the eastbound side. Traffic is already backing up past the lights, so it is worth going round if you have another way through.
Occasional updates on new features and how the community is growing. No spam, and you can unsubscribe whenever you like.
4Warning does not replace the police or emergency services. In an emergency, always contact them first.
Be aware. Warn others. Become part of the community. 4Warning is free on iPhone and Android — see it, share it, avoid it.
