Platform Guide

iOS vs Android vs React Native vs Flutter — which is right for you?

The right platform depends on your audience, budget, and timeline. Here is how we think about it — and what we recommend for different types of projects.

Not sure which fits your project? We will give you an honest recommendation on a free 30-minute discovery call — we suggest the platform that fits your goals, not the one that maximises our billing.

Book a Free Discovery Call

Choose native iOS if:

  • Your primary audience is in Australia, US, or UK where iPhone market share is 50%+
  • Your app needs Face ID, Apple Watch, Health Kit, or ARKit integration
  • You are building a premium consumer app where polished iOS UI is a competitive advantage
  • Your users are predominantly on iPhone and expect a fully native feel
Swift Xcode App Store iOS Development Services

Choose native Android if:

  • Your primary audience is in India, South Africa, or Southeast Asia where Android dominates at 70%+
  • Your app needs integration with Android-specific APIs or manufacturer hardware
  • You are building for enterprise environments where Android device management is standard
  • Maximum flexibility over the Android ecosystem is a key requirement
Kotlin Java Google Play Android Development Services

Choose React Native if:

  • You need to reach both iOS and Android — React Native cuts cost by up to 40%
  • Your team has JavaScript or React experience to leverage for mobile
  • You are building a marketplace, SaaS tool, on-demand platform, or e-commerce app
  • Speed to market matters more than platform-specific optimisation
JavaScript iOS + Android OTA Updates React Native Services

Choose Flutter if:

  • You need a highly customised, visually distinctive UI that looks identical on both platforms
  • Your app has complex animations or graphics-intensive screens
  • You want a single codebase that also compiles to web and desktop in future
  • Performance in UI-heavy applications is a top priority

Why CrestCoder

What makes us different

We are a specialist mobile team, not a generalist agency. Every project gets dedicated senior engineers from day one.

Dedicated mobile developers

Your team works exclusively on your project — not web developers assigned to mobile as an afterthought.

Both platforms, one team

You never coordinate between separate iOS and Android vendors — one team owns the full mobile delivery.

NDA before work begins

Your app idea, source code, and business data remain yours. Mutual NDA signed on every engagement.

Full project visibility

Sprint demos every two weeks. Jira or Slack access throughout. No black-box development.

Time-zone overlap

Built-in overlap hours for clients in Australia, UK, and South Africa on every engagement.

Store submission included

We handle App Store and Google Play submission end to end — listings, screenshots, compliance, and review management.

How We Work

Our mobile app development process

Six predictable stages. You always know exactly what is happening and what comes next.

1

Discovery & scoping

We map your goals, target users, platform requirements, and technical dependencies into a detailed scope, timeline, and cost breakdown.

2

UI/UX design

Wireframes and high-fidelity Figma designs for both platforms, validated with user flows before development starts.

3

Agile development

Two-week sprints with a working app demo at the end of each — you always see real, testable progress on both platforms.

4

Quality assurance

Every feature is tested on real iOS and Android devices. Functional testing, performance testing, and edge-case scenarios before each release.

5

App store submission

We handle the full submission process for both Apple App Store and Google Play Store, including screenshots, descriptions, and compliance checks.

6

Post-launch support

Optional monthly retainer for monitoring, crash fixes, OS update compatibility, and continued feature development on both platforms.

Common Questions

Frequently asked questions

Still have questions? Contact us directly.

A simple single-platform app typically starts around $5,000–$10,000. A mid-complexity app for both iOS and Android usually ranges from $20,000 to $60,000. A full-featured marketplace, enterprise, or SaaS app can range from $60,000 to $200,000+. We provide a detailed fixed-price proposal after a free discovery call so you know exactly what you are paying for before work begins.
A simple app with standard features typically takes 8–12 weeks. A mid-complexity cross-platform app usually takes 3–5 months. Complex enterprise applications with custom backends and extensive integrations typically take 6–9 months. Every project gets a milestone timeline in the proposal, tracked and reported on weekly.
If your primary audience is in Australia, the US, or UK, start with iOS. If your audience is primarily in India, South Africa, or Southeast Asia, start with Android. With React Native or Flutter you can launch on both simultaneously at significantly lower cost — which is what most of our clients choose.
Native apps are built specifically for one platform — Swift for iOS, Kotlin for Android. They offer the best possible performance and full access to platform features. Cross-platform apps built with React Native or Flutter share most code between both platforms, reducing cost significantly while delivering a near-native experience. For most business apps, cross-platform is the right choice.
Yes. Most mobile apps require a backend — an API, database, authentication system, push notification service, and often real-time infrastructure. Our team builds backends using Laravel, Node.js, or Firebase depending on requirements. We can also integrate your app with an existing backend or third-party services like Stripe, Twilio, or Google Maps.
Yes. We manage the entire submission process for both stores — store listings, screenshots, descriptions, and compliance documentation. We also handle the review process and any feedback from either platform's review team, including addressing rejections and resubmitting.
Yes. We offer flexible monthly maintenance retainers covering OS compatibility updates, crash monitoring, bug fixes, security patches, performance improvements, and continued feature development. All retainer clients get a dedicated point of contact and agreed response times. Plans scale up or down based on your needs.
