More in the labWe're always prototyping the next thing. Some ideas make it, most don't.
Approach

Small team. High standards.

Design first

Every screen is crafted, not assembled. If it isn't delightful, it isn't done.

Private by default

We collect only what a product needs, never sell personal data, and don't run ads.

Ship fast, learn faster

We launch early, listen closely and improve every week, with real users and real data.

How we work

From idea to everyone's phone.

01

Find the need

Start from a real question people ask, in their own words.

02

Prototype

Build the smallest version that feels great to use.

03

Launch

Ship on the web and the App Store, and tell the story.

04

Grow

Measure, listen, iterate. Then do it again.
