Dark-Sky & Tides
Offline GPS, tide, dark-sky, and field-planning tools for trail, water, land, and night-sky work.
What Gloamfell does
Offline outdoor tools that work from GPS and the phone's own sensors for land, water, trail, and night-sky planning, with saved sites and exports.
Thirteen modules: parcel acreage and boundary tracing with KML, CSV, and GPX export, barometric altimeter and hike recorder, pocket barometer and weather-trend log, pace-count distance, solunar feeding windows, campsite darkness and moon planning, offline tide and current prediction, GPS waypoint return, live star chart, light meter and exposure planning, golden-hour and twilight times, moon phase calendar, and a deep-sky object catalog.
