Mobile App Design & Development
Build one mobile product for iOS and Android, designed around the way your customers or team actually work.
We design and develop cross-platform mobile applications using React Native, from product planning and UX through backend development, testing, and App Store launch.
Based in Santa Rosa · Serving businesses throughout the Bay Area and beyond
Yard Sign Tracker
A field operations app built for teams placing and retrieving yard signs across large geographic areas.
The workflow previously depended on remembering sign locations and landmarks manually. We built a mobile application that records locations, organizes field activity, and helps users return to signs later.
Key capabilities
- GPS-based sign tracking
- Drive mode
- Interactive maps
- Landmark tracking
- Route guidance
- User accounts
- Role-based access
- Cloud-backed data
A manual field workflow turned into a purpose-built mobile experience. iOS + Android from one shared React Native application. This is stronger than making the section feel like a feature list alone.
Build for iOS and Android Without Maintaining Two Separate Products
For many business applications, React Native lets us share much of the same code across iOS and Android.
That can reduce duplicated development, simplify maintenance, and make it easier to release features across both platforms.
One shared development foundation
Much of the application logic and interface can be shared across both platforms.
Two production releases
Deploy to both Apple’s App Store and Google Play from the same core application.
Platform-specific flexibility
When iOS or Android requires platform-specific behavior, we can implement it without rebuilding the entire product.
More Consistent Improvements
New functionality can often be developed once and rolled out across both platforms.
Mobile App Development for Every Product Stage
Whether you are starting with an idea, moving an existing workflow to mobile, or improving an application you already have, the first step is defining the right scope.
Launch a New Mobile App
For businesses turning an idea or existing workflow into a new mobile product.
Common needs:
- Product discovery
- UX/UI
- MVP development
- Authentication
- Backend setup
- App Store launch
Bring an Existing Product to Mobile
For businesses that already have a website, platform, or web application and need a dedicated mobile experience.
Common needs:
- Existing API integration
- Shared authentication
- Mobile-specific UX
- Push notifications
- Mobile workflows
- App Store distribution
Improve or Rebuild an Existing App
For products that have become difficult to maintain, slow to improve, or inconsistent across devices.
Common needs:
- UX redesign
- Performance improvements
- React Native migration
- Backend modernization
- Technical debt reduction
- Feature expansion
From product planning through launch
We coordinate the product experience, mobile development, backend systems, integrations, testing, and release requirements as one connected project.
Product Strategy & MVP Planning
Turn the idea into a defined first release before committing to unnecessary development.
- Feature prioritization
- User flows
- Technical planning
- MVP scope
Mobile UX/UI & Prototyping
Design the flows and screens users will interact with before development begins.
- Wireframes
- Interface design
- Interactive prototypes
- Design system
React Native App Development
Develop the production mobile application for iOS and Android.
- React Native
- Expo
- Native integrations
- Production builds
Backend, APIs & Admin Tools
Build the systems behind the app that manage users, data, permissions, and business logic.
- Authentication
- Databases
- APIs
- Admin dashboards
Testing & App Store Launch
Validate the product across devices and prepare production releases.
- Device testing
- iOS builds
- Android builds
- Store submissions
Maintenance & Product Growth
Continue improving the product after real users begin using it.
- Bug fixes
- Platform updates
- New features
- Performance improvements
Clear starting ranges before a detailed proposal
Every application has different workflows, user roles, integrations, backend requirements, device features, and release needs. These ranges help establish the expected level of investment.
Focused Mobile MVP
$5K–$10K
For a tightly scoped first product with a small number of core workflows.
Production Mobile App
$25K–$50K
For a polished production product involving custom UX, authentication, backend services, integrations, and App Store launch.
Complex Mobile Platform
$50K–$100K+
For advanced applications involving multiple roles, significant backend functionality, integrations, location services, payments, complex workflows, or continued product development.
These are planning ranges, not fixed package prices. Final scope depends on features, integrations, backend requirements, design complexity, and launch requirements.

Plan Your Mobile App →
A defined path from idea to release
Our phased process connects product requirements, UX, backend architecture, development, testing, and launch—and creates clear review points before the project advances.
Discovery & Product Scope
Define the users, problem, core workflows, business requirements, and first release.
UX & Technical Planning
Map screens, user flows, data, APIs, integrations, permissions, and application architecture.
Development & Testing
Build the app incrementally, review progress, test workflows, and validate on real devices.
Launch & Improvement
Prepare production builds, support App Store releases, monitor the product, and continue improving it after launch.
A Mobile App Is More Than the Screens
Production applications often require authentication, databases, APIs, admin tools, third-party services, analytics, and deployment infrastructure. We plan those pieces together instead of treating the mobile interface as an isolated project.
One Connected Product Plan
The mobile app, backend, admin tools, integrations, analytics, and release requirements are treated as parts of the same product.
Cross-Platform Development
Use one shared React Native foundation instead of funding two completely separate app projects from the beginning.
Beyond the Mobile Screens
Support the app with authentication, databases, permissions, APIs, payments, cloud services, and administrative dashboards.
Defined Phases & Review Points
Understand what belongs in the first release, what can wait, and how new requirements affect the budget and timeline.
Capabilities Matched to the Project
Product, design, development, QA, and specialist support are coordinated according to the actual application requirements.
Bay Area & Remote Collaboration
Based in Santa Rosa and serving Sonoma County, the North Bay, the wider Bay Area, and remote clients.
Questions before you get started
How much does it cost to build a mobile app?
Most production apps vary significantly based on functionality. Focused MVPs may begin around $5K–$10K, while custom business applications commonly require larger budgets depending on backend functionality, integrations, and product complexity.
Do you build both iPhone and Android apps?
Yes. We typically use React Native to build a shared application for iOS and Android while retaining the ability to implement platform-specific functionality when needed.
Can you turn my existing website or web app into a mobile app?
Often, yes. If your existing platform has reusable APIs and authentication, the mobile application can connect to the same backend rather than rebuilding the entire system.
Do you help submit apps to the App Store?
Yes. App Store and Google Play preparation can be included in the project.
Can the app connect to our existing website or business software?
Yes, when the existing system provides a suitable integration path. We review the platform, available APIs, authentication, data structure, and security requirements first. Older systems may require a new API or integration layer.
Can you build the backend too?
Yes. We can build or integrate authentication, databases, APIs, admin tools, and other services needed by the mobile application.
Do I need a mobile app or would a web app be better?
That depends on how users interact with the product. Apps make more sense when users return frequently, work in the field, need device capabilities, or benefit from a dedicated mobile experience. We can help determine the right approach before development.
Who owns the application and source code?
Ownership, repository access, developer accounts, source-code responsibilities, third-party licenses, and handoff requirements are documented in the project agreement before development begins.
Have an app idea or a workflow that belongs on a phone?
Tell us what you're trying to build, who will use it, and what problem it needs to solve. We'll help define the right first version before you invest in development.
