Field
Log an observation with no signal required
Species, count, habitat, behavior, and GPS-derived county all save locally the moment an observation happens, regardless of connectivity.
Built for the field, not the WiFi.

THE PROBLEM
A birding notebook that needs signal isn’t a field notebook
Good birding happens in exactly the places cell signal doesn’t reach — so a logging app that depends on connectivity to save an observation fails at the one moment it matters most.
HOW IT WAS BUILT
Offline-first, with real Clean Architecture underneath
Birding Field Companion logs observations — species, count, habitat, behavior, GPS, and county — entirely locally first, backed by Drift over SQLite and structured with Riverpod-driven Clean Architecture.
Species, hotspot, and audio packs install independently and on demand, and a sync outbox reconciles offline work once the device is back online, so nothing about the core logging loop depends on a connection.
INSIDE THE PRODUCT
Core surfaces that define the experience
Content
Species, hotspot, and audio packs on demand
Installable, independently versioned packs let the app carry deep regional content without bloating the base install.
Content scales with what a birder actually needs.
Sync
A queue, not a requirement
A local sync outbox holds offline writes and reconciles them once back online, so logging never blocks on network state.
Connectivity is a convenience, not a dependency.
KEY FEATURES
What makes it work
Offline-First From the Ground Up
Every observation logs locally with GPS and county lookup first, with sync treated as an eventual reconciliation step rather than a requirement for the app to function in the field.
Installable Packs, Independently Versioned
Species, hotspot, and audio content ship as independently versioned packs that install on demand, keeping the base app light while still supporting deep regional content.
Sync Queue, Not Sync-or-Fail
A local outbox queues writes made while offline and reconciles them once connectivity returns, instead of blocking the core logging workflow on network availability.
WORKFLOW
How a field session runs
Birding Field Companion is built around logging in the field first, syncing later.
01
Log the observation offline
Species, count, habitat, behavior, and GPS-derived county save locally with no connection required.
02
Install packs as needed
Species, hotspot, and audio packs download on demand, versioned independently of the base app.
03
Sync once back online
A local outbox reconciles offline writes automatically once connectivity returns.
