Rebar · Photo-point monitoring

Same spot. Same shot.

Rebar is a photo-point monitoring app for restoration and conservation groups. It guides you back to each photo point, lines up the original shot, and builds the before-and-after pages funders ask for.

Coming to iPhone and Android

The problem

Photo-point monitoring means retaking a photo from the same spot, year after year, to prove a site changed. In practice, points get lost, volunteers change, and repeat photos drift until they can’t be compared.

01 · Return

Find every photo point.

Distance and bearing to each station, plus the notes and marker photos left by whoever set it up. The person retaking a photo is often not the person who took the first one.

02 · Align

Match the original shot.

A see-through overlay of the baseline photo, with compass and tilt guides and a buzz when you’re lined up. Alignment is recorded, not required. You can always take the photo.

03 · Handoff

Built for volunteers.

Coordinators send stations to volunteers as a single file. Volunteers shoot and send their photos back. No accounts, and no cell service needed in the field.

04 · Report

Funder-ready before and after.

Side-by-side pages with the fields funders ask for: grant number, station ID, coordinates (decimal degrees or UTM), bearing, stage, and date. CSV export included.

05 · Evidence

Photos you can stand behind.

Time, location, and bearing are recorded at capture and can’t be edited afterward. Each photo gets a SHA-256 fingerprint so anyone can confirm the file hasn’t changed since it was taken. A fingerprint proves the file is unchanged, not what it shows.

06 · Privacy

Private by design.

Projects, photos, and site locations stay on your devices. Nothing is uploaded, and files move only when you share them.

Try Rebar before launch.

We’re looking for a few restoration and monitoring groups — watershed and conservation groups, land trusts, conservation districts — to use Rebar on real projects before release.
