Field Duo
A pocket notebook for iPhone Duo.
Coming soon to the App Store

You won't believe it's not paper.
Kraft covers, ruled pages and a real page turn, split right at the fold. It feels like the notebook in your back pocket.

Make it yours.
Mix materials, patterns, colors, type and photos into thousands of covers. Every one lands in your library.




Wear it in.
The more you use a notebook, the more it ages. Faded kraft, softened corners, the odd coffee ring.
Use it like the real thing.
Scroll your shelf to pick a notebook, then open your Duo to write in it.

Write, list, attach.
Type notes, make checklists and drop in photos.
Flip through.
Pages turn under your finger, just like paper.
48 pages.
Every notebook has a real page count, so it fills up.
Volumes.
Run out of pages and pick up where you left off in Vol. 2.
Handwriting.
