Offline-first ranger tracking and field data collection

Document events with photos and custom fields, capture patrol tracks in the background, upload documents, and view everything in a centralized dashboard. Works completely offline — syncs when online.

The map shows a sample ranger track. Replace with actual app images in production.

Our Mission

Ranger App is built to empower conservation teams with reliable, offline-first tools for wildlife monitoring, ranger tracking, and community engagement.
Our mission is to strengthen conservation efforts worldwide by making field technology accessible, open source, and community-driven.

Event documentation — images, notes & custom fields

Create detailed event records in the field: attach photos, add descriptions, and use custom fields (for example, animal counts, observed threats, or community notes). Everything stored locally and queued for sync.

Background ranger tracking & patrol maps

Rangers’ locations are recorded in the background to create patrol tracks. View lines and stop points on the dashboard to validate coverage and detect gaps.

Works completely offline

Offline-first design: collect data without connectivity and let the app sync automatically later. Local queues are robust and reliable for remote deployments
