Mobile App Development in San Jose, CA
If the person reading this wants to know what's actually in the repository before agreeing to anything, that's who we build for in San Jose. Every mobile app we ship, Android, iOS through Flutter or React Native, or a PWA when that meets the requirements, comes with its own API, a test suite, a CI pipeline, and a staging environment your team can poke at before launch. Builds run $2,500 for a narrow scope up through $15,000 and beyond for a full connected product, priced by a free audit rather than a rate card. If your team already runs a backend, we build against it instead of standing up a competing one.
What's actually in the repository
Every project ships with a Git repository your team has access to from day one, a test suite that runs on every pull request, and a CI pipeline that builds and deploys to a staging environment automatically. The same discipline runs our own site: more than 1,800 automated checks run before anything ships.
For a San Jose engineering team, that usually matters more than any feature list on a landing page. Your own engineers can read a pull request, run the app locally from the same repository, or take over the whole codebase later without a handoff meeting, because there's nothing tribal-knowledge-only about how it was built or where the pieces live.
Wiring into your existing backend
Most San Jose companies asking about a mobile app already have an API, or at least a database and some internal tooling. We build the app to talk to that directly rather than standing up a parallel backend you'd have to maintain forever afterward. Where the existing API is solid, the mobile app becomes mostly a client for it. Where it isn't built for mobile traffic yet, spotty connections, smaller payloads, we say so in the audit and scope the fix as its own line item.
If there's no backend yet, we design and build one alongside the app, with the same API-first approach: the API gets written and tested on its own first, and the mobile app is treated as one of possibly several clients that consume it, a web dashboard being another likely one down the line.
Stack choices default to whatever your team already runs. If the backend is already on a particular cloud, a particular database, or a particular auth provider, the mobile app's API layer is written to fit that, not to introduce a second stack your engineers now have to learn to support the one new client. Where there's no preference either way, we say what we'd pick and why, and leave the final call with your team.
How a release actually happens
The same steps a software team already runs internally, applied to a mobile app.
- A free audit and API review before any code is written
- A scoped backlog with acceptance criteria per feature
- Pull requests reviewed and merged against a staging branch
- Automated tests run on every change
- A staging build on TestFlight or a direct APK link for internal testing
- Store submission, or a direct release, under your own developer account
None of this is unusual for a software team; it's unusual for a consumer-facing mobile app vendor, which is the gap we're filling for San Jose companies that want an app built the way their own engineering organization already works.
Monitoring and error tracking go in before launch, not after the first support ticket. A crash on a customer's phone should show up in a dashboard with a stack trace attached, not get discovered secondhand through a one-star review weeks later. That's a piece of engineering discipline that a lot of app-development shops skip to hit a lower quote, and it's usually the first thing that costs a client real money once it's missing.
What a technically-scoped app costs
A narrow app or an internal tool with a small surface area runs $2,500 to $6,000. Something wired to a real API with tests and CI, the more common case here, is $6,000 to $15,000. A full product with several clients, roles, and a build pipeline across environments starts from $15,000.
Small, tested, real CI.
- One workflow, with a CI pipeline behind it from day one
- PWA or a narrowly scoped native build
- Typically 2 to 4 weeks from a scoped backlog
Built against a real API.
- Built against your existing API, or a new one designed alongside it
- Automated tests and CI from the first sprint
- Staging and production environments
Multiple clients, multiple environments.
- Multiple roles, environments, and release channels
- Full monitoring, error tracking, and a security review
- Delivered in two-week increments your team can review
Work outside a scoped project, a one-off script, a config change, is billed at $150 to $200 an hour. After launch, ongoing support and on-call coverage for bugs runs $300 to $500 a month for a smaller app, or $750 to $1,500 a month once faster response times and active feature work are both part of the deal. Both live on the pricing page; the general build process is on the mobile app development page.
Working with a San Jose engineering team
We're in Sacramento, about two hours north. Code review, standups, and the build all run in the repository and on video calls, the same as they would across a desk. When it's worth the drive, a kickoff to align on architecture with your own engineers in a room, or a launch day, we'll come down; most of the technical back-and-forth happens asynchronously in pull requests either way, on whatever schedule your team already keeps.
Picture a logistics startup that needs a driver app that reads and writes to its existing internal API, roughly $11,000, including test coverage and a CI pipeline matching their existing standards. Your own scope depends on what your API already supports and how much of it is documented.
Mobile is one of seven things we do, and rarely the only thing a business needs. If the project is really a website, start at web design in San Jose. For custom software beyond the app itself, see software development in San Jose. If the process needs AI inside it end to end, that is AI automation in San Jose.

What San Jose engineering leads ask before signing off on a mobile build.
What does a mobile app cost for a San Jose engineering team?
A small, tested app starts from $2,500. Something built against a real API with CI and staging environments runs $6,000 to $15,000. A full multi-environment product starts at $15,000, fixed by a free audit before work starts.
Who has access to the repository and the pipeline?
Your team does, from the first commit, in your own GitHub organization if you have one. There's no separate copy of the code that only we can see, and no CI account you'd have to ask us to hand over later.
Can our engineers review the code before it ships?
That's the expectation. Pull requests are open for review as they're written, and we'd rather get a comment mid-sprint than a rewrite request after launch.
Do you build against our existing API or design a new one?
Against yours, by default, if it's solid enough for mobile traffic. We only propose a new one when the audit shows the existing API can't support what the app needs, and we'll show you exactly why before building it.
What does the release process actually look like?
Tests run automatically on every pull request, a staging build goes out through TestFlight or a direct link for your team to try, and production releases go out under your own developer account, on a schedule you approve.
