Silicon Valley-caliber engineering for ambitious products. We build custom mobile apps for iOS and Android, native where performance demands it and React Native where a shared codebase pays for itself. Every engagement covers the parts that decide whether an app survives launch: an architecture that can take a second feature, analytics you can act on, store submission handled for you, and a maintenance path once real users arrive. No offshore handoff — the people who scope your app are the people who build it.
The Bay Area is where much of the SaaS, AI and developer tooling market is built, and buyers here tend to judge vendors on architecture, test coverage and how quickly a team can ship. Investor diligence often reaches the codebase, so clean ownership of code and accounts matters.
Deep integration with Bay Area's SaaS and AI ecosystem. We build products that meet Silicon Valley standards: scalable, investor-ready, and designed for hypergrowth.

Every Mobile App Development project in San Francisco is built with full compliance to local and international regulatory frameworks.
Every Mobile App Development project we deliver in San Francisco includes these enterprise-grade features, customized for Bay Area's specific market requirements.
Swift and Kotlin where native matters, React Native where it does not, decided on your requirements rather than our preference.
The team that scopes your app writes it. No junior handoff after the contract is signed, and no offshore subcontracting.
A written scope and a fixed price per phase, so the number you approve is the number you pay.
App Store and Play Store listings, screenshots, privacy manifests and Data Safety forms, review responses and resubmissions.
Instrumented before launch, not after, so the first week of real usage tells you something you can act on.
OS upgrades, dependency patches, store policy changes and bug fixes under a monthly agreement rather than ad hoc invoices.
We use industry-leading technologies proven at scale by the world's top companies. Our stack is optimized for Bay Area's infrastructure and regulatory requirements.

A mobile app is a larger commitment than a website because it lives on someone's phone, gets reviewed by Apple and Google, and has to be updated as operating systems change. San Francisco founders tend to come in with strong opinions about the product and fewer about the plumbing: authentication, push notifications, offline behaviour, analytics and crash reporting.
Store rules are the first regulatory layer. Apple requires apps that offer account creation to also offer account deletion inside the app, and both stores require accurate privacy disclosures about the data you collect. California adds CalOPPA, which covers mobile apps that collect personal information from residents, and the CCPA and CPRA for businesses that meet the thresholds. Apps for children face COPPA at the federal level, and health or location data deserve extra caution in design and in your disclosures.
Cost is shaped by whether you build native for each platform or use a shared codebase, the number of screens, backend needs, payments, and real time features like chat or live tracking. Ask a provider who submits the app and under whose developer account, how they handle store rejections, what monitoring is in place after launch, and how a minor operating system update will be handled and billed.
