Cross-platform app development in Santa Monica — React Native and Flutter applications delivering near-native quality with unified codebases.

Santa Monica Cross-Platform

React Native & Flutter

Single Codebase

Challenges we solve

Ideas don’t scale. 
Products do.

We turn raw concepts into fully functional apps that work across platforms from day one.
One team, one codebase,
full coverage — with performance that feels native, everywhere.

Design breaks between platforms.

Shared components built.
Edge cases resolved.

Features lag behind across versions.

Native quirks handled.
Stability aligned.

App crashes on one OS,
not the other.

Touch-first UX mapped. Navigation rebuilt.

User flows feel clunky
on mobile.

Codebase unified.
Update cycles synced.

Who we work with

Startups

You’ve got the idea — we’ll
get it to App Store and Google Play, fast. One codebase.

Core flows shipped fast
MVP logic streamlined
App store requirements handled

Launch without delay

Small businesses

Feature creep, platform drift, scaling issues — we help you stay focused while your app evolves.

Design systems synced
Edge-case bugs squashed
Shared libraries built

Scale without friction

Corporations

Multiple platforms, large teams, millions of users — we build stable, maintainable apps built to last.

Legacy integrations planned
Release cycles automated
Performance optimized across OS

Deliver at scale

The mobile side is fine — why isn’t desktop?

Because platforms don’t share assumptions.

The layout adapts — but the inputs behave differently. The API calls work — but session storage breaks. The animations run — but accessibility tags don’t.

If the foundation isn’t cross-platform, the polish
won’t matter.

What goes into cross platform apps development?

Designed once. Felt everywhere

We design for consistency — not just compatibility.
Every interaction feels right and native.

One UX language

Native feel across OS

Single codebase, zero compromise

No Frankenstein frameworks. We build for reuse without sacrificing performance.

Shared core

Optimized rendering

Built for change

Need new features? We ship them once —
and they just work.

Future-ready

Update-safe

Tested where it matters

We test in real devices, not just emulators. Bugs don't slip through platform cracks.

Multi-platform QA

Real-user flows checked

Sure your app is built to scale?

What our clients say

Michelle Vo

Marketing Director

What impressed me most was how Toimi combined design sense with technical detail. Every idea was backed up by reasoning, and they weren't afraid to challenge us if it meant a stronger outcome.

Lina Chen

Operations Director

We had a pretty complex setup request. They broke it down, kept us updated at every step, and delivered earlier than we thought possible.

Rajesh Patel

CEO

Clear process, fast approvals, no drama. Exactly how a project should run.

Piotr Kowalski

Project Manager

We'll definitely continue working together.

How does Toimi handle shared codebase trade-offs between React Native and Flutter for Santa Monica clients?

We architect cross-platform apps maximizing code reuse while accommodating platform differences where they matter. Business logic, state management, API communication, most UI components are shared. Platform-specific code is isolated cleanly. For Santa Monica clients, this architecture typically delivers 80-90% code sharing.

Can Toimi integrate React Native or Flutter apps with Santa Monica companies' existing native codebases?

Yes — both frameworks support brownfield integration: adding React Native or Flutter components to existing native iOS and Android apps. For Santa Monica companies with established native apps wanting to add features using cross-platform technology, we handle integration complexity.

How does Toimi handle updates and ongoing maintenance for Santa Monica cross-platform projects?

Cross-platform maintenance has specific considerations: framework version updates, dependency churn, platform OS updates requiring framework compatibility, native module maintenance. We offer Santa Monica clients maintenance engagements handling these ongoing concerns systematically.

What is the typical timeline and cost savings for cross-platform vs native dual-platform development for Santa Monica clients?

Cross-platform typically delivers iOS and Android in 60-75% of the time required for native dual-platform development. A project taking 24 weeks for native iOS + Android might deliver in 14-18 weeks as React Native. Cost savings are often 30-40% for the initial build. These efficiencies make cross-platform attractive for Silicon Beach-backed Santa Monica startups balancing runway with feature delivery.

What is cross-platform app development and when is it right for Santa Monica companies?

Cross-platform development uses frameworks like React Native or Flutter to build iOS and Android apps from a shared codebase — reducing development cost, accelerating time-to-market, simplifying maintenance. Santa Monica companies choose cross-platform when targeting both platforms is required but native dual-platform exceeds budget, target experience can be achieved without platform-specific UX differentiation, engineering teams have web (JavaScript, TypeScript) expertise translating to React Native, or features focus on business logic rather than platform-specific capabilities.

Does Toimi recommend React Native or Flutter for cross-platform Santa Monica projects?

Both are excellent choices with different strengths. React Native fits Santa Monica teams with JavaScript/TypeScript expertise (most Silicon Beach web developers), integrates well with React ecosystems, enables sharing code with React web applications. Flutter delivers slightly better performance in some cases and offers excellent custom UI capabilities. For most Santa Monica clients, React Native is pragmatic choice given talent alignment.

What kinds of Santa Monica apps work well with cross-platform frameworks?

Cross-platform excels for business and productivity apps, content-driven apps, B2B tools, social and communication apps, moderate-complexity commerce apps, dashboard/admin applications. Cross-platform works less well for graphics-heavy games, AR/VR applications (particularly relevant given Santa Monica's AR emphasis — Snap AR remains firmly native), apps requiring deep platform capability integration.

Can Toimi deliver genuinely native-quality experiences with cross-platform frameworks?

Yes — modern React Native and Flutter can deliver experiences indistinguishable from native for most user flows. This requires discipline: proper platform-specific UI conventions, optimized performance, platform-specific features where they matter. Santa Monica clients investing in proper cross-platform development get excellent outcomes.
