  • This app hasn’t received enough ratings or reviews to display an overview.

Anchor watch: reliable on every device, even offline • With the Bosun via Bluetooth your phone alerts even without internet. • Acknowledging applies on all devices; unacknowledged alarms repeat every 2 minutes. • “Position unknown” with a reason and “position uncertain” with weak GPS. • Its own alarm tone; the phone reports lost GPS reception and keeps going after a dead zone. • New bottom bar: Anchor as its own tab, checklists under “More”.
