We turn everyday friction into simple mobile experiences. Thoughtfully designed. Built to be useful.
A little space for your next big idea.
Our first project is Primus Pocket: a simple place to collect thoughts, organize what matters, and make room for your next step.
That half-formed thought might be the start of something good.
Capture a note in seconds. Give it a category. Turn a good idea into a small, doable action. Try the working preview today, right in your browser.
Open the previewA quick thought, a useful link, a small reminder. One simple input, with room to come back to it later.
Separate ideas from actions. Save the notes worth returning to. Find a thought without digging through a long list.
The preview stores notes in your browser. No account to create and no AI service processing your notes in this version.
Labo Primus is the mobile product studio of Catalyst Brands LLC, founded in New Mexico in September 2025. We are developing focused consumer apps that make ordinary moments feel a little easier.
We begin with a small problem worth solving, then make the experience feel clear from the very first tap.
Readable interfaces, fewer decisions, and useful defaults. We design for the person using the app, not the feature list.
We are exploring Claude for note summaries and suggested next steps. AI features are on our roadmap and are not active in the current preview.
Capture, categorize, search, save, and complete notes. Use Primus Pocket on a phone or desktop and help shape the product.
An iOS and Android experience, with optional AI-assisted organization. Native releases and AI features are still in development.
