iPhone Duo

Finally, a phone that opens like a notebook.

So we made a notebook that opens like one too. Penna was sketched around iPhone Duo from the very first page.

One notebook, three ways to hold it.

iPhone Duo closed with one page, half open with the page above the tools, and open flat as a spread

Keep a page open for reference

Choose Refer To and any page from any notebook or PDF sits on the left half, read-only, while you write on the right. Slides beside your notes, the brief beside the sketch, the recipe beside the shopping list.

The Library splits at the fold

Open flat, Recent, Favorites and your folders sit on the top half and the covers on the bottom. Thumbs on either side, everything one tap away.

Your finger is a pen

On iPhone, your finger writes. With no pressure to go on, Penna watches your speed instead: quick strokes come out fine, slow ones come out full. It feels more natural than it has any right to.

Write it down. Then find it again.

Penna arrives on iPad, iPhone and Mac this fall. Leave your email and we'll send you exactly one message: the day it's out.
