Mobile Game Development & Porting

Mobile Game Development & Porting

From RuneScape Mobile to hypercasual prototypes. iOS and Android builds optimised for performance on every device.

Cross-Platform Mobile Expertise

We build high-performance mobile games for iOS and Android using Unity, the engine behind over 70% of the top mobile titles worldwide. From casual puzzles to complex multiplayer experiences, we handle the unique challenges of mobile: device fragmentation, battery management, touch-first UX, and store compliance. Our team has shipped titles that reached millions of mobile players, including contributions to RuneScape Mobile (reaching #1 RPG on the App Store with 10 million players worldwide). Under the Ocean View Games banner, we built Pocket Factory from concept to App Store for Mojo Games, ported and modernised Nova Blast to Android for Foil Hat Games, and shipped educational titles to both platforms. Every build goes through rigorous performance profiling and multi-device QA.

Mobile Game Porting

Already have a PC or console game? We specialise in porting existing titles to iOS and Android without starting from scratch. Our porting process begins with a technical audit of your existing codebase to determine what can be reused and what needs rewriting. For Unity projects, we can typically retain over 80% of the original game logic, focusing development effort on redesigning the UX for touchscreens, optimising rendering and memory usage for mobile hardware, and meeting Apple and Google platform requirements. You provide the build and any available source code; we deliver a mobile-native experience. Typical porting timelines range from 3 to 6 months depending on the complexity of the original title. Read the full technical breakdown in our RuneScape Mobile porting case study, or see our Nova Blast SDK modernisation and Android porting case study for a smaller-scale example.

iOS Game Development

We build and optimise for the full Apple ecosystem. Our iOS game development covers Metal-optimised rendering through Unity's URP pipeline, Safe Area layouts for every device generation, TestFlight beta management, and full compliance with Apple's App Store review guidelines.

Android Game Development

Android's device diversity demands a specialist approach. Our Android game development uses tier-based optimisation, classifying devices into performance brackets with adaptive quality settings that scale automatically. We target the latest API levels and test across a broad hardware matrix from budget handsets to flagships.

Our Mobile Services

🍎

iOS & Android Development

Native Unity builds for both platforms with shared codebase, platform-specific APIs, and compliance with Apple and Google submission requirements.

👆

Touch-First UI/UX

Intuitive gesture controls, virtual joysticks, haptic feedback, and Safe Area adaptive layouts that feel native to mobile - not a clumsy PC port.

🧪

Device Testing & QA

Comprehensive testing across a wide range of devices, screen sizes, and aspect ratios - from budget Android phones to the latest iPhones and iPads.

🚀

App Store Deployment

End-to-end submission to the Apple App Store and Google Play, including build validation, store asset creation, and compliance reviews.

⚙️

Mobile Performance Tuning

Efficient shaders (URP), draw-call batching, texture compression, and frame-rate limiting to prevent overheating and maximise battery life during play.

🔄

Mobile Game Porting

We port PC and console titles to iOS and Android. We assess your existing codebase, identify what can be reused, redesign the UX for touch, and handle store submission.

Why Choose Us?

📱

Mobile-Native Unity Builds

We build once in Unity and deploy natively to iOS and Android with platform-specific optimisations: Metal rendering on Apple devices, Vulkan on Android, adaptive input systems, and store-compliant build pipelines from day one.

🏆

10M+ Mobile Players Shipped

Our team contributed to RuneScape Mobile reaching #1 RPG on the App Store. Under Ocean View Games, we have shipped Pocket Factory to both stores for Mojo Games and ported Nova Blast to Android for Foil Hat Games.

Thermal & Battery Profiling

We go beyond frame rate. Our mobile optimisation process includes thermal throttling analysis on mid-range Android devices, battery drain profiling, and tier-based adaptive quality that scales rendering across budget and flagship hardware.

Our Mobile Development Process

Mobile development requires a unique approach. We follow a rigorous 4-step workflow designed to navigate device fragmentation, strict App Store guidelines, and user retention mechanics.

1. Concept & Mobile UX Strategy

A great mobile game starts with the user interface. We design “thumb-friendly” layouts and plan your monetisation strategy early to ensure high retention.

  • Wireframing: Mapping out user flows to ensure menus are intuitive on small screens.
  • Monetisation Design: Integrating Ads or In-App Purchases (IAP) naturally into the core loop.
  • Technical Spec: Defining supported Android API levels and iOS requirements.

2. Engineering & Optimisation

We build on a shared codebase using Unity, allowing simultaneous deployment to iOS and Android while keeping performance high.

  • Efficient Coding: Writing C# scripts optimised for ARM processors to reduce battery drain.
  • Asset Compression: Optimising textures and audio to keep the initial download size (APK/IPA) small.
  • Regular Builds: Delivering playable prototypes via TestFlight and Google Play Internal Track every sprint.

3. Device Testing & QA

Your game needs to work on a budget Android phone just as well as the latest iPhone. We stress-test on real hardware, not just emulators.

  • Fragmentation Testing: Verifying UI scaling across different aspect ratios (notches, tablets, foldables).
  • Performance Profiling: Ensuring a stable 60 FPS without overheating devices.
  • Compliance Checks: Pre-validating the app against Apple and Google review guidelines to prevent rejection.

4. Store Submission & Launch

We handle the administrative headache of releasing a game. From certificate management to the final “Publish” button.

  • Store Setup: Configuring store listings, age ratings, and privacy policies.
  • App Store Optimisation (ASO): Advising on keywords and screenshots to maximise organic downloads.
  • Live Operations: Implementing analytics tools (Firebase/Unity Analytics) to track player behaviour post-launch.
