WaterNav is unique in that it has been developed so that you can access all date even without an active internet connection. (It works offline once the maps are downloaded) It monitors you location using the phones inbuilt GPS, giving your precise location on the map. The maps display thousands of continually updated points of interest (such as pubs, shops, vets, diesel, moorings, etc), as well as all the waterway information such as locks, bridges, turning points, etc, and canal closures. It is the essential towpath companions for boaters, ramblers, cyclists, or anyone else enjoying the waterways. The route planning options and enhanced options are available once you create an account (no charges or obligations) and with options of picking location, searching for a location or using your own current position it provides lots of flexibility. You can also chose journey times, lock delays and speed. River Canal Rescue members will automatically be granted access to a special RCR interface that will offer exclusive features. RCR members will be able to access their membership details, see their RCR history, log callouts, book services, and request additional works. They will also be able to utilise a new arrival aid system which will allow them to track their engineer in real time. The WaterNav App is in ongoing development (our inhouse developers will respond to all requests or issues - just remember it can take time to get issues updated). There are new updates and development of new features and we are resolving issues continually. ( so make sure you regularly update, and let us know if we can make things easier for you)
Small Group Tracker
Read full descriptionHide full description
Small Group Tracker shares live location with a small group — up to 6 people — during a walk, hike, festival, or day out. One person creates a group and shares a QR code; everyone else scans it to join. From there, everyone's position, messages, and points of interest travel directly between phones over an encrypted peer-to-peer connection. Nothing is stored on a server, and no account or sign-up is required. MAIN FEATURES Live group map Everyone in the group appears as a coloured pin on the map, updating automatically as people move. Quick join by QR code No usernames or passwords. Scan a code, enter your name, and you're on the map. Group messaging Send a message to everyone in the group instantly, with a notification sound. Panic button One tap alerts every group member with an alarm and your last known location, for genuine emergencies. Points of interest Drop a shared pin — a meeting point, parking spot, or landmark — visible to the whole group, and export it for reuse. Automatic expiry Every group has an expiry time. When it passes, or the Coordinator ends the event, all group data is deleted. PRIVACY BY DESIGN Your location never touches our servers — it travels directly between your group's phones.
