Available on iOS · Android coming soon · 14-day free trial
Every feature designed around what coastal SAR crews, RNLI volunteers, and Coastguard teams actually need on a shout.
Real-time positions of HMCG helicopters, RNLI lifeboats, air ambulance and police aircraft on the map. Tap any asset to see registration, operator, base, altitude, speed, heading and vertical rate. Powered by OpenSky and AIS — updated every minute.
Create a named crew group and share a 6-digit PIN. Every member sees the rest of the team live on the map with last-seen timestamps. Toggle map visibility on and off. Built for coordinating SAR teams in the field without switching apps or exchanging phone numbers.
Push notification the moment an RNLI vessel or SAR helicopter launches near you. Delivered to your iPhone and Apple Watch. Configurable alert radius so you only get notified about activity that matters to your station.
Live Met Office observations plus 24-hour forecast. Wind speed, gusts, direction, cloud base, visibility, temperature and pressure. Every readout includes an operational status — CONDITIONS GOOD, MARGINAL, or BELOW MINIMA — so you know immediately whether conditions are taskable.
Admiralty tidal predictions for any UK coastal station. Full tidal curve chart — 24, 48 or 72 hours ahead. Current height, next high and low water, tidal range, spring tide warnings, neap and spring indicators. Nearest station shown automatically.
Drop a pin and get the W3W address instantly. Search by ///words to jump to any location. The compass view gives bearing and distance to any W3W pin — navigate directly to a casualty location without leaving the app or losing your place on the map.
Ordnance Survey Outdoor, Road and Light map styles switchable at any time. Opacity slider for hybrid viewing. Offline cache option downloads map tiles before you enter an area with no signal — critical for remote coastal and cliff rescue operations.
Toggle over 10 data layers on a single map: SAR bases, RNLI stations, HMCG locations, Coastal Rescue Team positions, live aircraft, active lifeboats, HLS sites with exact coordinates, community-submitted HLS verified by ClearBase admin, and tidal surge monitoring stations. Mark any HLS as a favourite — starred sites persist until manually removed.
Helicopter Landing Sites are submitted by the community and verified by ClearBase admin before appearing on the map. Each site shows exact coordinates, so you can relay an HLS position to an inbound aircraft without reaching for another app. Mark sites as favourites and they stay pinned on your map until you remove them. No other coastal app has this.
