AQUASCOUT Get the APK

Android 8+ · two classes only

Fire and smoke detection that runs where the camera already is.

A 3.3 MB YOLOv8n model runs on your handset's CPU. When it sees fire or smoke, it texts your emergency contact with the GPS pin. Nothing is uploaded. There is nothing to install but the app.

The box and the number are the product. Everything else is the phone you already have.

What it does

Four jobs, done on the phone.

Detects
Two classes only, fire and smoke. A focused model does one job better than a general one.
Alerts
SMS to one number you choose, with the phone's GPS pin. Works on any carrier, needs no app on the receiving end.
Keeps quiet
Frames never leave the handset. Firebase stores your alert log, not your camera. See the trust boundary
Lets you override
Smell smoke before the camera sees it? Hold the red button for a second and a half.

How it works

Three steps, no server in the middle.

  1. STEP 01

    The phone looks

    The camera feed goes straight into the TFLite interpreter. No upload, no round trip, no waiting on a signal.

  2. STEP 02

    The model decides

    Boxes above your confidence threshold become detections, each one labelled fire or smoke with a score you can see.

  3. STEP 03

    Somebody is told

    If you do not acknowledge it, the alert escalates by SMS to your emergency contact with your coordinates attached.

On the phone

The whole interface.

Two screens, taken from the build on this page. The detector runs on the handset, so what you see is what the phone is doing, not a mock-up.

The honest caveat: candles, cigarettes and steam scored high enough to trigger on an earlier build and still need re-testing. The sensitivity threshold is adjustable in Settings.

Get the app

Point it at a room. See what it does.

Android 8 and up. Detection works without an account; signing in only adds log sync across your devices.

Join on Google Play

Recommended. Sign in with the Google account you were added with, tap Accept, then install from the Play Store. Until the store listing is finished the app appears under the temporary name com.scc.aquascout (unreviewed). That is the same app.

Download APK 1.56

The same 1.56 build, sideloaded. No Google account needed. Your browser will ask once, the first time, to allow installs from it. Installing this way does not register you as a Play tester.

Already installed it from Google Play? Uninstall that one first. Play signs its build with its own key, so Android refuses to install one over the other.

To send an SMS alert, paste your Semaphore API key into Settings first. Without it the detector still runs and logs detections, but no message is ever sent.
