Why consumer apps fail search and rescue call-outs

Group chat is fine for organising a meeting. On a call-out, the message that matters is easy to miss and everyone is typing at once. Search and rescue teams do better with a proper radio setup on the phones they already carry.

What a group chat gets wrong

Messages scroll away, people talk over each other, and positions have to be typed or pasted in by hand. By the time someone has found and shared a location, the search has moved on.

What push-to-talk does instead

With RevoNet, one person speaks at a time and everyone in the group hears them. The map shows where each volunteer was last seen, so the coordinator can see the shape of the search and send people where they are needed. It runs on volunteers' own phones, so there is nothing extra to buy or carry.

Building good habits before you need them

Practise. Agree who speaks when, keep messages short, and use the same group names every time. Run a short exercise on a training night so everyone is comfortable with the button and the map before a real call-out.

After stand-down

A timeline of the call-out helps with the debrief: who was where, and when. It makes writing up a lot quicker.

Common questions

Do volunteers need a work phone? No. RevoNet runs on the personal phones volunteers already carry.

Can we keep our current radios as well? Yes. Many teams run both and use whichever suits each part of the ground.

How much training does a new volunteer need? Very little. The habits from radio training carry straight over, and the app itself is simple.

Can a small team try it for free? Yes. You can register with up to two users and practise before rolling it out to the whole team.
