The app is compatible with Bluetooth Low Energy devices:

  • VIVHO Tag - smart finder for keys, phone, wallet, bag, simply anything.
  • VIVHO Tag Kids - smart bracelet which lets you know if your child is lost in the crowded areas: shopping center, beach, museum, stadium, holidays, etc.

How it works:

  • Separation Alarm: immediate alarm from your smartphone when you walk out of range of VIVHO Tag.
  • The app shows the last GPS position on the map where you lost contact with VIVHO Tag.
  • Press VIVHO Tag button to ring your phone.
  • Ring VIVHO Tag with 90 dB alarm.
  • Wi-Fi Silent Zones: select trusted Wi-Fi networks - while you are connected to them, Separation Alarms will be disabled, so you can avoid unwanted alarms.
  • Remote camera control: press VIVHO Tag button to take a perfect photo.

App connects with VIVHO Tag devices using Bluetooth 4.0 Low Energy (BLE) technology. Working range is up to 50m for VIVHO Tag and up to 80m (open area) for VIVHO Tag Kids.
