Field-ready. Offline-first.
The mobile app is made for outdoors: capture without a connection, rugged operation in sunlight and with gloves, and a sync that takes over as soon as there is signal again.
Offline capture
Complete observations entirely without a connection. Everything is stored locally in SQLite with an FTS5 full-text index.
Automatic sync
The sync queue uploads as soon as you are back online. Conflicts are detected and resolved.
GPS & swisstopo map
Set the location via GPS or map; MapLibre base maps from swisstopo, cached offline too.
Taxon picker
Full-text search across scientific and common names, fast and fully offline.
Glove-friendly
Large touch targets (≥ 44 px) and high contrast for sunlight and rough field conditions.
Photo & audio
Attach media right at the site; compressed and uploaded with the next sync.
