App Developers & Software Development Company in Charleston, SC
Code and Trust is a Charleston, SC-based team of app developers and software engineers operating out of Mt. Pleasant since 2018. We scope every project in writing before a line of code is written, hand over full source-code ownership on delivery, and back every launch with 90 days of included support.
Software development company in Charleston, SC — the short answer
Code and Trust is a software development company based at 665 Johnnie Dodds Blvd #201, Mt. Pleasant, SC 29464, operating in the Charleston, SC metro since 2018. The team builds custom software, mobile apps, and AI automations under fixed-price contracts with full IP transfer — no recurring licensing fees, no hourly surprises.
App developers in Charleston, SC
Code and Trust's Charleston-area app developers build iOS and Android apps in React Native — a single codebase covering both platforms, which lowers build cost versus separate native apps. Charleston founders and businesses work directly with the build team, not an account manager relaying updates from an offshore desk.
Hiring app developers locally means someone can sit across the table for a requirements session, walk through a working build in person, and answer a question same-day instead of across a nine-hour time zone gap. That is the whole case for a Charleston-based team over a remote-only shop or an agency headquartered somewhere north of the Mason-Dixon line.
Every app engagement — mobile or web — starts the same way: a written scope with a fixed price, agreed before any code exists. See the full breakdown of what that looks like for mobile specifically at mobile application development services, or for a browser-based product at custom software development services.
What Charleston businesses build with Code and Trust

Custom software & internal tools
Full-stack web applications and internal tools scoped in writing before any code is written. Fixed price at signing, full source-code and IP transfer at delivery.

React Native mobile builds — one codebase for both platforms. Field-service apps, consumer apps, and mobile companions to an existing web product.
Learn more →AI workflow automation
Audit-first AI implementation — automations scoped only where they demonstrably cut manual work, not bolted on for the sake of it.
Learn more →Legacy system modernization
Replace aging software with a maintainable, documented codebase. Zero-downtime cutover with a written handoff at the end.
Learn more →Why Charleston companies choose a local software development company
A Charleston-based software company delivers the same engineering quality as a national firm, plus in-person availability, federal-program proximity near NIWC Atlantic, and South Carolina overhead instead of Washington, DC or Northern Virginia rates. That combination is why local businesses default to a Charleston team first.
In person, not just on Zoom
The Mt. Pleasant office is a short drive from downtown Charleston, so kickoff meetings, demos, and stakeholder reviews can happen face to face whenever it matters.
Federal-adjacent engineering
Close enough to NIWC Atlantic and Joint Base Charleston that cleared engineers can support program work on-site when a contract requires it.
Plugged into the SC startup scene
Ongoing involvement with DigSouth, the Charleston Digital Corridor, and the Harbor Entrepreneur Center ecosystem — not a firm that flew in for one project.
South Carolina rates, not Beltway rates
Operating cost in the Charleston metro runs well below Washington, DC and Northern Virginia — the savings show up directly in the fixed-price quote.
How a Charleston engagement works, start to finish
Every Charleston engagement runs through the same four stages: a written discovery and scope document, a signed fixed price, two-week engineering sprints with live demos, and a launch backed by 90 days of included post-launch support. Nothing starts until the price is on paper.
- 01
Discovery & written scope
A short discovery pass turns your requirements into a written scope document with a fixed price attached — before any engineering work begins.
- 02
Signed, fixed price
You review and sign the scope. The price is locked at that point; there is no hourly clock running and no line-item surprises later.
- 03
Sprints & weekly demos
Development runs in two-week sprints with a demo at the end of each one, so progress is visible in a working build, not a status deck.
- 04
Launch & 90-day support
Production deployment includes full source-code and IP transfer, plus 90 days of included post-launch support for anything that comes up after go-live.
