Independent software studio

Useful tools.
Nothing in the way.

One Thirteen is a small team making focused software for Mac and iOS—apps that respect your time, protect your data, and earn their place on your screen.

Our story

One Thirteen started as a side project between two brothers who wanted to build software they would actually use. No venture funding or growth playbook—just useful tools made with care.

We are based in Delaware and work on our apps independently. Features ship when they are ready, shaped by real use rather than artificial deadlines.

How we work

Local-first

Your data stays on your device whenever possible. Our tools are designed to work without an account or a permanent cloud dependency.

Private by design

We do not build businesses around personal data. What you do inside our apps is your business, not a product to be packaged and sold.

Made with care

Details matter. We build slowly, use what we make, listen to real feedback, and resist adding complexity for its own sake.

The team

Nick Development & design Writes the code, shapes the interfaces, and obsesses over the details.

Jack Ideas & direction Brings the ideas, tests the builds, and keeps the work grounded.
