Log the rock.Pick the rock.

Rocks surface every season. Rock Picker lets anyone on the farm drop a pin on crisp satellite imagery the moment they spot one — so the picker crew can drive straight to it later and mark it picked. No signal required.

Field procedure

Three steps. Gloves on.

01

Join the farm

Enter your farm's code and your name once. Every launch after that goes straight to the map — the whole crew uses the same code.

02

Tap to log

Spot a rock from the cab? Tap it on the satellite map, confirm, done. Placement by eye on the imagery beats bouncing in-cab GPS.

03

Pick & mark

The picker crew drives pin to pin, marks each rock picked (with undo for stray taps), and the pin drops off the map.

No bars, no problem

Dead zones don't stop the crew.

Every pin is saved on the device first and synced to the cloud whenever a connection returns. Satellite tiles for your fields download ahead of time — automatically on WiFi — so the map stays crisp at deep zoom in airplane mode.

Acceptance test: airplane mode on, app restarted, everything still works.
Field UX

Built for gloves, glare & a bouncing cab

Max-size touch targets

Every control is sized to hit with a work glove on the first try.

High contrast

Readable in full sun through a dusty windshield.

One action to log

Tap the rock, confirm. No forms, no typing, no menus in the field.

Nothing gets lost

Status history is append-only — every log and pick is recorded with who and when.
