PLUed
Trains grocery cashiers on produce PLU codes with spaced repetition and a verified code library.
An app development studio, AI enabled
The idea is no longer the barrier. Finishing is.
Arbolinea - Ideas above the treeline
Arbolinea ships finished things: apps for learning, number theory, objects from the workshop. We are the idea; the machine is the leverage. The craft is the method: getting it right the first time, or in far fewer tries.
Software
Apps
Shipped through the stores and maintained for real users.
Timed Math Pro
Arithmetic drilling that rewards speed and accuracy. A ground-up rebuild of a paid app customers have used for over a decade.
Tetradec
In development. More soon.

Imagine taking the ideas you have always had and turning them into real products. The question was never what you wanted to build. You have always known that; the wanting is yours, not the machine's. Every barrier was a how: knowledge (how do I?), cost (if I do not know how, who do I pay?), and time (how long to learn, and what does it cost if it takes too long?). The hows just fell. Finishing is what is left, and finishing is what we do. Two ways to work together, each one ending with something you can use without us.
01
Take an idea to shipped
Honest validation first: what already exists, where you differ, and whether the idea deserves the money. Then we build it, ship it, and hand you a product built to be maintained with AI at low cost, sometimes even on a free tier.
02
Revive an existing app
Modernize an aging app, make it maintainable with an affordable AI workflow, and hand your team the method.

On the tool
Ideas come easy now. The machine can generate them, design the piece, and suggest a better one. We will not pretend it cannot. We also will not pretend we have its memory or its speed. What we have are wants: we know what we like, we know the future we want, and we build what makes us and others measurably better. The machine has no wants. We do. So when we say AI, we mean exactly what an engineer means by a calculator, or a woodworker means by a table saw. A tool.
On the market
The tool is not free. There is a monthly bill, and a harder question under it: which one? Grok, Codex, Kimi, Claude, all of them, or whatever ships next week? Then which model, which mode, which plan? Is the new one better? Better at what: writing, code, price? The answers change month to month, sometimes day to day. We watch the landscape constantly and pick what fits the work. We will not pretend that choice is settled. It never stays settled.
On platforms
Every project starts as a website: the cheapest, fastest way to find out if an idea is real. Most never need to be more than that. The few that do, we build as apps you install from the App Store or Google Play, and we take them through those stores properly.
The studio
About
Arbolinea is run by Clay Elmore: nearly three decades in enterprise learning and analytics, much of it in leadership. Also: Eagle Scout, former firefighter and EMT, lifelong outdoor enthusiast. The treeline in the name is a real place: the line where the trees stop and the view begins. We crossed it for the first time on Longs Peak. The studio exists to prove a simple point: one person can now take an idea all the way to finished.
