Eight colours. A single pull.

The alarm hits 130 dB measured at 30 cm, roughly a jet engine heard from 30 metres away. Sharp enough to throw someone off at close range and to pull eyes from the far side of a street, a platform or a car park.

It does. The 130 dB alarm and the flashlight run entirely on their own: no phone, no app, no signal. A phone comes into play only for the extras, meaning one-tap emergency calling and live location sharing.

Several weeks of ordinary carrying on one full charge. A couple of hours on USB-C fills it back up, and a short top-up carries you through the week, so it is awake whenever you are.

Only the emergency contacts you picked, and only once you start a share or set off an alert. Nothing is followed in the background: your position stays yours until you choose to send it out.

Firing OYA takes a deliberate press and hold rather than a quick tap, so it will not go off by itself in a bag or a pocket. Should it ever happen, a couple of seconds is enough to cancel it. No false alarms on the bus.

Splashes and rain are fine, so daily carrying, a sudden downpour or a sweaty run pose no problem. Swimming and full immersion are outside what it was built for.
