Under motor, paddle or oars. A Bluetooth BMS or a coulometer on the pack adds live values and range.\n\nNavigation\n* Set a destination on the map: straight line or a route along the waterways, with distance and estimated draw\n* Load map data onto the device, then route offline up to 600 km\n* Craft type, motorboat or canoe, decides which bans apply\n* Locks and weirs on the route, tap one for hours, phone and chamber size\n* Seamarks are tappable, speed signs show their number\n* Map north up or course up, marker and map glide\n\nSpeed and trip\n* Large readout, km/h or knots, decimals configurable\n* Start and stop through a foreground service, keeps measuring with the screen off\n* Trip history with distance, times, Ah, Wh and Wh/km, GPX export and import\n* Satellite and GPS status, smoothing of the raw value\n\nBattery (Bluetooth LE)\n* Several packs, wiring single, parallel or series\n* Voltage, current, state of charge, remaining Ah, temperature, cells\n* Range and remaining time at the current speed, time-averaged\n* JBD and Redodo/LiTime/Power Queen verified on hardware, Daly and JK experimental\n* Coulometer with a Hall sensor for packs without Bluetooth, verified too\n* Charging mode with time to full and an alert at a chosen level\n\nWeather and safety\n* DWD rain radar, readings from the nearest station, wind direction\n* Weather warnings for thunderstorm and storm\n* Anchor watch with a drag alarm\n\nWhat the app talks to\n* Base map from OpenStreetMap, seamark overlay from tiles.openseamap.org\n* Waterway tiles for routing from boatspeedy.wozise.de, a server run by the author. The data comes from OpenStreetMap, the generator is open source (Glenn-Dandy/boatspeedy-mapdata)\n* Without matching tiles, routing asks the public Overpass servers\n* Weather and warnings from the Deutscher Wetterdienst, via maps.dwd.de and api.brightsky.dev\n* Update check at api.github.com, only when you tap it\n\nFree and open source, without Google Play Se","categories":["Navigation","Sports & Health"]}
