Cross-Platform Apps: Build Once, Deliver Across All Devices
.png?length=500&name=Usability%20Testing-1%20(11).png)
A cross-platform app is a mobile or web app built with one codebase that works on multiple platforms—like iOS and Android—ensuring consistency across devices.
Why It Matters
-
Reduces development cost and time by avoiding platform-specific builds
-
Enables broader reach across user bases (Android, iOS, even web)
-
Easier updates and fewer bugs thanks to shared codebase
-
Ideal for MVPs and budget-conscious startups
-
Supports faster scaling and maintenance over time
Use This Term When...
-
You’re comparing native vs cross-platform options
-
Planning an MVP with limited budget or timeline
-
Discussing development frameworks like Flutter or React Native
-
Defining a tech stack that prioritises fast delivery
-
Coordinating updates across different device types
Real-World Example
In the project, we delivered a high-performing cross-platform app using Flutter, enabling the client to maintain one codebase across Android and iOS while saving 40% on development time.
Founder Insight
Most users can’t tell the difference between native and cross-platform apps—especially with modern tools. Prioritise reach and scalability early on. If performance demands rise later, you can optimise as needed.
Key Metrics / Concepts
-
Code Reusability Rate: % of code shared across iOS/Android
-
Performance Benchmark: Speed, responsiveness vs native
-
Time to Market: Launch time saved by unified builds
-
Crash Rate by Platform: Monitors platform-specific issues
-
Maintenance Overhead: Fewer bugs to fix = less dev time
