App Development
A purpose-built web app for your small team — spec, prototype, build, launch.A custom app build for small teams. We start with a free chat to confirm an app is the right answer, write a tight spec, prove the riskiest flow with a clickable prototype, then build a hardened production app with auth, data, integrations, tests, and monitoring. Web-first with mobile-friendly responsive design.

00// matrix position
Where this fits in the services matrix.
Every service page now names the buyer state, the commercial shape, and the next route. That keeps the catalog navigable instead of feeling like disconnected offers.

00B// application system
Bespoke architecture for App Dev.
App Development needs more than screens. It needs auth, data, workflows, integration paths, QA, and a clear deployment loop.

01// what you walk away with
The outcome, not just the output.
- 01A live, custom web app your team and customers can use
- 02A spec, a prototype, then a real production app — in that order
- 03Tests, monitoring, and a runbook so the app survives without me
- 04Mobile-friendly responsive design out of the box
02// scope
Concrete artifacts you keep — and what we leave out.
Working code, written docs, dashboards your team owns. We also list what this engagement deliberately does not cover, so scope is honest before you click.
// deliverables
- Free 20-minute intro chat
- Plain-English product spec with milestone-based pricing
- Clickable prototype of the riskiest flow
- Production app: auth, database, UI, integrations
- Cross-device QA + accessibility + perf + security passes
- Loom + written runbook + two weeks of bug-fix support
// not included
- Native iOS / Android apps (web-first; we ship responsive web apps and PWAs)
- Long-term hosting bills (your AWS / Vercel / Render account, your costs)
- Open-ended scope expansion (changes go through written change-control)

04// questions
Common questions.
01Why does the price start at $6,500?
Real apps need auth, data, tests, and monitoring on day one — not after launch. The starting price covers a tight scope with those baked in. Bigger apps quote higher; small internal tools may quote lower.
02Web app or native app?
Web-first. Modern web apps install to home screens, work offline, and ship 10x faster than native. If you genuinely need native, I will say so on the intro call and refer out.
03Can you take over an existing app?
Yes — start with Sage Audit ($750) so I understand the codebase, then we scope a continuation engagement honestly.
04What if my idea is too small for $6,500?
Then it might be a Ship (marketing site), an Automate (one workflow), or a Build (broader engagement). The free intro chat is the fastest way to find out.

app system
From offer to operating system.
App Development is presented as a real engagement, not a generic service page: the surface, backend shape, delivery artifacts, and conversion path are all visible before the first call.
