Custom software, shipped end to end.
We design, build, and maintain web apps, mobile apps, and desktop software for founders who can't afford an agency. One owner-operator, end to end — from concept to the App Store.
Full-stack, all platforms.
One owner-operator, four platforms, one accountable builder. We write the server, the client, the mobile, and the Windows installer — and we stay on to maintain them once they're shipping revenue.

One operator.
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're building under our own name. They're our proof of work — and the systems we rely on to test our own stack.
CaseFlow
MailMoney
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.
An independent software company. Not an agency.
JH App Group is a Colorado-registered LLC run by one owner-operator. You work directly with the person designing, building, and maintaining the software — no sales handoff, no agency layers.
We believe lean independence, 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 person building it.
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.
