Porch-light regulars, robin last calls, and the fox that always cuts through at dusk.
What you log from the window
Each row is one part of the roll call loop — no account, no cloud, just your corner of the world.
Ten-minute sessions
Pick morning, midday, or evening, start the timer, and log each visitor — species, count, behavior, weather, and a short note.
Timeline & regulars
Browse roll calls by day and see who keeps returning to your porch light with monthly visitor rankings and morning-vs-evening splits.
Share cards
After each session, copy a plain-text summary of sightings — perfect for texting a friend who also watches the same tree branch.
Six screens, one windowsill
Roll call home, live session, entry sheet, timeline, regulars, and settings.

Thrumfield is a local wildlife journal. Your roll call sessions, species entries, and notes are stored only on your device. We do not collect, transmit, or sell personal data. The app does not require an account.
Thrumfield does not use third-party analytics or advertising SDKs. If you contact us by email, we use your message only to respond to your request.
Because data stays on your device, deleting the app removes your session history from that device. You can also clear all sessions from Settings inside the app.
