An independent mobile-app studio

Small apps.
Room for
everyday life.

We’re Orbinook. We build personal mobile apps with Claude as a core development collaborator. Our first chapter: a diary that feels like your own little corner of the world.

01 / The first chapterIn development

Meet your
everyday notebook.

For people who want to write a little more often—and make the space their own. Orbinook Diary brings your words, personal backgrounds and a little encouragement together.

The diary prototype's journal with two fictional sample entries and an Everyday moments folder.Your days, collected.
01

Put the day into words.

A title, a few honest lines, a saved entry. Find your writing again and organize it into folders.

02

Choose your atmosphere.

Illustrated scenes, gradients, animated backgrounds and personal photo slideshows make the space feel like you.

03

Keep a little momentum.

Writing goals, reminders, XP and achievements bring small moments of progress into a daily habit.

02 / Our development collaborator

Built with Claude.
Growing with Claude.

Claude is part of how we’re building Orbinook for the long term.

It has already contributed to the diary’s initial implementation and later interface refinements. We want to deepen that collaboration as we turn new ideas into useful apps.

03 / Beyond one appThe App Factory direction

A thoughtful process.
More ideas to come.

Behind the diary is a wider ambition: a repeatable way to research an app idea, define what matters, build it with Claude and check the result.

01 / Understand

Start with a real need.

Gather evidence and make a clear product brief.

02 / Develop

Work with Claude.

Bring requirements, code and feedback into the same conversation.

03 / Verify

Check what was built.

Use tests and human review before carrying a change forward.

App Factory’s market-discovery agent is initialized. Later stages and the Claude API integration are planned.

Inside our process
The next page

One app idea.
A complete, checked cycle.

Our next milestone is to take one candidate through a documented Claude-assisted workflow, keeping its inputs, proposals, revisions and checks together.

Today, the diary is a development prototype. We’re using what we learn from building it to shape the process behind the next app.
