🦦 Pebble
🦦 A field guide to wherever you are

Learn the name of
something you walk past.

Point your phone at a weed in a pavement crack, a bird on a wire, or the memorial on the corner. Pebble tells you what it is — and the one surprising thing about it worth repeating to someone that evening.

Not a search box. A reason to look.

Plenty of apps will identify a plant. They all wait for you to already be curious. Pebble is built the other way round — to make ordinary ground worth a second look.

The fact, not just the name

Every find comes with one true, surprising sentence. Not a taxonomy lesson — the thing you'd actually tell someone.

🪶

Plants, animals, and places

Bridges, memorials, odd little bits of civic history count too. Useful in February, and useful in a city.

📔

A record of where you've been

Every find is kept with your photo, the place, the date, and room for your own notes. A diary, not a database.

How it works

  1. Point and scan. Your phone makes an instant guess on-device, before anything is sent anywhere.
  2. Check the answer. You get ranked possibilities, each with a real photo, what was spotted in your picture, and how sure Pebble is. You decide which is right.
  3. Keep it. The find joins your PebbleDex with its photo, place and date — and earns XP. Finding the same thing somewhere new, or in a new season, counts again.

Built to be honest

A confident wrong answer is worse than an honest "not sure".

It says when it isn't sure

Uncertain scans get a second opinion from a stronger model, and you always see the confidence behind each suggestion.

It won't invent history

For places with no recorded past, Pebble says so rather than making one up.

Your finds stay yours

Photos, notes and locations live on your phone. Location is never sent with a photo.
