Single-user, fully offline Android field app for trail monitoring & maintenance — live GPS, offline vector maps, tasks with photos, route recording, structures & inspections, segment-timed work, and trail-condition reports. No backend, no account: all data stays on the phone; backup/restore and GPX are the only bridge out.
