MobileFlare turns your phone screen into a colour-coded distress signal, readable at distance, usable offline, and understood without a word.
Why MobileFlare exists
At a live event, something goes wrong. The music is loud. The crowd is dense. There is no signal. You cannot move. You need help, right now, and nobody around you knows it.
MobileFlare was built from personal experience of exactly this moment. Standing in crowds at concerts across the UK, watching performances stop for safety concerns, watching stewards struggle to locate people in distress, watching other audience members look helplessly at each other, the same question kept returning: if something serious happened right now, how would anyone know?
"I've seen performances stop mid-set at multiple concerts. I've watched stewards push through crowds toward an incident nobody could locate quickly. The performer sees something is wrong. Security sees something is wrong. But finding the person who needs help, in a standing crowd of thousands, takes time nobody has."
The answer to that question already exists in your pocket. Your phone screen is the brightest, most visible object on your person. MobileFlare simply puts it to work.
The events that shaped this
These are not hypothetical situations. Crowd emergencies have claimed lives at events around the world, and in almost every case, the people who needed help had no reliable way to make themselves visible.
In every one of these situations, a visible, colour-coded signal from a phone screen would not have solved everything. But it would have made people in danger findable. And that matters.
Using MobileFlare
MobileFlare is deliberately, uncompromisingly simple. In an emergency, you will not have time to navigate menus, log in, or read instructions. The app is designed to work in the worst possible moment.
The app opens directly to the four emergency buttons. No login, no loading screen, no permissions prompt. It is ready immediately.
Press and hold for under a second. The brief hold prevents accidental activation, an important safeguard in a crowded environment.
Your screen activates at full brightness in the appropriate colour. Emergency signals flash to maximise visibility. Water Please shows as a calm, steady blue screen. Hold your phone above your head. Security, stewards, medical staff, and performers can see it from distance.
Anyone who has downloaded MobileFlare, or seen the colour code at a venue, knows exactly what you need before they reach you.
Why there's nothing to lose
We built MobileFlare to remove every possible barrier to adoption. If you can think of a reason not to download it, we want to hear it.
Works completely offline. No Wi-Fi, no mobile data, no Bluetooth. It works anywhere your phone works.
MobileFlare collects nothing. No name, no location, no usage data. We do not know you exist.
No account, no email, no password. Download and it works. A brief responsible use guide appears on first launch. That's it.
MobileFlare is free to download and free to use. There are no in-app purchases, no adverts.
Four buttons. Under a second to activate. If you can unlock your phone, you can use MobileFlare.
Maximum screen brightness during activation. Designed to be seen across a dark venue floor.
Each signal flashes at a different speed as well as a different colour. Green is slowest, yellow faster, red fastest. MobileFlare is distinguishable by colour-blind users too.
A built-in share button generates QR codes for both the App Store and Google Play. Show someone at an event and they can download it in seconds, before the night is over.
A non-emergency feature that helps friends find each other in a crowd. Choose one of four distinct colours from the main menu and show your screen. Kept completely separate from the emergency signals so there is no risk of confusion.
A message for parents
Younger audiences are attending live events in record numbers. First concerts, first festivals, first experiences of large crowds, often without the adults who would know what to do if something went wrong.
At a sold-out standing concert, the ambient noise level can exceed 100 decibels. A person shouting at the top of their voice will not be heard beyond three or four people in any direction. In a crowd crush, they may not be able to move at all.
Young people instinctively reach for their phones in a crisis. MobileFlare gives that instinct somewhere useful to go.
It requires no prior training, no calm thinking under pressure, and no signal. Just the ability to hold a button.
Before your child goes to their next event, spend thirty seconds showing them MobileFlare. The four colours. What each one means. Where to find the app on their home screen.
That thirty seconds is the whole conversation. The app does the rest.
