ToneGuard® recognises a scream, stress in your voice, an impact and the words you choose, and sends your location to the people you trust. Four products, one system: the app, a Bluetooth bracelet, a 4G bracelet and a 4G watch.

Set up a centre for seniors or people at risk: platform, EU servers, equipment, bracelets and watches, delivered to you. Or let us run the monitoring.
Start with the app. Add a Bluetooth bracelet, a 4G bracelet or a 4G watch.

The same system, shaped for the people who need it most.
A button needs a free hand and a quiet moment. ToneGuard® also watches for the signs that something is wrong and combines them before it alerts, to reduce false alarms.
Every function shows its real status.
Measures the pitch, loudness and sharpness of your voice against your own calm baseline, so it can tell shouting and screaming from normal speech. You calibrate it once: calm voice, whisper, shout.
Record a word or phrase in your own voice. The app recognises it later, even when you say it quietly. Only numbers are stored, never the recording.
Word lists for help and aggression in the app's languages. One word never raises an alert alone: the app asks "Are you OK?" or waits for a second sign.
A background service keeps watching with the screen off. The sound is analysed on the device, not streamed anywhere.
Detects violent shaking, a hard impact or a thrown phone, even when the app is not on screen.
Loud noise followed by sudden silence is treated as a serious warning sign.
A button in the notification: two taps with a short safety delay, no need to unlock the phone.
Before sending, the app asks you to confirm. A secret duress PIN looks like a cancellation, but the alert keeps going.
Your location and message go as an SMS from your own SIM card. With no signal, it retries automatically when the signal returns.
If you do not check in on time, or you leave a zone you set, your trusted people are alerted.
Audio and video evidence is encrypted on the phone. Only the recipient's private key can open it.
The app opens only with your fingerprint or face, so no one else can see its settings.
With a bracelet or watch, and only with your consent, your pulse is added to the alert SMS so the people who receive it have more context.
The bracelet's body-temperature reading is added to the alert SMS in the same update.
Romanian, English, French, German, Spanish, Italian, Hungarian, Bulgarian, Ukrainian, Turkish, Arabic, Polish, Portuguese, Greek, Hebrew and Albanian.
Voice, words, movement and silence are analysed on the phone.
Several signs together raise the risk. One weak sign only asks "Are you OK?".
Your location and message go by SMS to your trusted people. Recording starts, encrypted.
A person you trust, or an organisation's operator, takes over the case.
A web console for your team: alert queue, map, case take-over and audit log. Residents and beneficiaries wear a bracelet or a 4G watch, or use the app. Your team answers; ToneGuard® does not run a monitoring centre.

Every person is a point on the map and a line in the queue, coloured by status. Your team sees who needs help first.
The person pressed SOS, or a strong alert was raised. A person must take it now.
Something is off: a check-in was missed, the person left a safe zone, the device was removed or the battery is low. Check soon.
Connected, inside the safe zones, no alert.

The app is active on Android; some functions are built and still being tested, others are in preparation. Detection can make mistakes: false alarms and missed alarms.
