Custom software, shipped end to end.
We design, build, and maintain web apps, mobile apps, and desktop software for teams who can't afford a team of contractors. One studio. From concept to the App Store.
Full-stack, all platforms.
One team, four platforms, one accountable owner. We write the server, the client, the mobile, and the Windows installer — and we stay on to maintain them once they're shipping revenue.

Small shop.
Real operations.
We run production software with boring, grown-up infrastructure. Every number here is measured — not aspirational.
What we ship under our own name.
Products we've designed, built, and continue to operate. They're our proof of work — and the systems we rely on to test our own stack.

Command Center
Four phases. One owner.
We quote fixed scope on week-long discovery, then build in two-week increments with a shared staging environment. You see progress every Friday.
Discover
Scoping call, technical audit, written proposal with fixed price & timeline. Usually one week.
Design
High-fidelity prototypes in Figma. Two rounds of feedback before any code is written.
Build
Two-week sprints. Friday demos on staging. Production deploy at the end of each sprint if you want it.
Operate
Optional retainer for monitoring, bug fixes, store submissions, and new features. No lock-in.
A working studio. Not an agency.
JH App Group is a Colorado-registered LLC run by the engineers who do the work. You never hire a salesperson and hand off to juniors — because there aren't any.
We believe small teams, clean code, and stubborn focus beat spreadsheets of consultants every time.
We keep the company small on purpose. It lets us say no to projects we can't do well, stay deep in the stacks we commit to, and be on-call for the products we've shipped — without a Jira board between you and the people writing the code.
Privacy-first by default. Minimum data collection. Server-side credential management. Encrypted storage. We build software we'd be comfortable using ourselves.
As a registered U.S. LLC, we operate with full transparency and adhere to all applicable federal and Colorado state regulations governing software development and data handling.
