A living journal of your neighborhood.
Open the app on a Tuesday morning. See one sentence about a bird that visited the yard. See the neighborhood drawn. Close the app within thirty seconds knowing the day has already had something good in it.
That feeling is the product. Everything else is in service of it.
A vaux's swift was spotted nearby this morning.
Your neighborhood, drawn. Your yard outlined. Birds, creatures, and life pinned where they happened. One italic sentence tells you what stirred while you were sleeping.
Sightings within 250m of home. Yours — whether you logged them or a neighbor walking by did.
Fresh sightings, pulsing gently. Something was here this morning.
Other birders in the neighborhood. The ambient life of the area, quietly shown.
Not just birds — everything alive. A coyote at dawn, blackberries ripening, rain on the leaves. Your neighborhood's story, one entry at a time.
The screen Merlin doesn't have. Time-aware prompts, walk suggestions, and quests that give you a reason to step outside and notice the world.
Merlin + eBird data feeds Roost's heartbeat. You don't lift a finger — the neighborhood's birds just appear.
Tap + to log fauna, flora, or a moment. A coyote, a blooming tree, rain on the leaves. Two taps and a sentence.
Walk quests, time-of-day prompts, seasonal nudges. The app says "go outside" in the gentlest possible way.
Over weeks and months, your block develops a personality. The crows own 7th Street. The blackberries ripen in June. You know this place.
Merlin knows birds.
Roost knows your block.
Finding moments of awe
in each other, daily.
