San Francisco mobile app development — for founders who know what they want.
SF founders have seen the best mobile apps in the world. They know what good looks like. RCB Software builds San Francisco mobile applications with the quality standards that SF product culture demands — fixed-price.
San Francisco-based company that needs a mobile application built to production quality at a predictable cost
San Francisco mobile development costs are the highest in the country. Senior React Native engineers at SF companies command $200,000-$280,000+ annually. For pre-Series A founders: the economics of hiring don't work.
What SF founders need in mobile development:
- Apps that feel native, not like web-wrapped HTML
- Performance that doesn't embarrass the product in demo
- Architecture that doesn't require a full rewrite when the first engineer joins
- Fixed-price so the burn rate is predictable

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
SF burn rates are among the highest in the world. Fixed-price mobile development is a line item, not an open-ended cost center.
Questions, answered.
For most SF startup use cases: identical user experience, 95% of the performance, one codebase, one developer. The trade-off is worth it for pre-Series A companies.
