BioLog
Mobile app

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.
