Independent iOS studio

Small studio.
Thoughtful apps.

YellowGrayFox is a one-person studio crafting calm, considered tools for everyday life — built slowly, by hand, with care for the people who actually use them.

What we make

A small catalog, made with care.

Each app is built to do one thing well — no ads chasing you around, no dark patterns, no rush.

What we believe

Software, but make it human.

Three quiet principles guide every release.

01

Built for the long haul.

In Your Note has shipped since 2017. We don’t chase trends — we sharpen what works and keep it alive year after year.

02

Your data is your data.

No selling, no profiling, no sneaky trackers. iCloud syncing happens on your own Apple ID — never our servers.

03

Made by a person.

One developer, one designer, one customer-support inbox. When you write to us, an actual human writes back.

The studio

Hi, I’m Stephen.

YellowGrayFox is the name I put on apps I build outside of my day job. The logo started as a doodle in a sketchbook — a small gray fox on a swatch of yellow watercolor — and it stuck. It’s a reminder to keep things modest, warm, and made by hand.

I make these apps in the evenings and weekends. If something’s broken, or you wish it worked differently, just say so — I read every email.
