Frequently Asked Questions
Why choose Flutter over native development (Swift/Kotlin)?▼
Flutter allows you to build for iOS, Android, and the web using one unified codebase. This drastically reduces initial development costs and ensures feature parity across all platforms. Instead of maintaining two or three separate codebases, updates and bug fixes roll out everywhere instantly without sacrificing native performance.
What are the benefits of working with a local app developer in the South West?▼
Partnering with an experienced local specialist based in Devon means you deal directly with the senior engineer building your product—no layers of account managers, miscommunicated briefs, or offshore delays. We offer face-to-face or direct video consultations, ensuring deep alignment with your business goals across Devon, Cornwall, Somerset, Dorset, and the wider UK.
Can Flutter apps handle complex audio streaming and offline playback?▼
Yes. Flutter is exceptionally well-suited for media-heavy applications. Utilising advanced background audio packages and local caching, apps built on this stack can stream high-bitrate audio seamlessly, manage lock-screen playback controls, and offer reliable offline caching for users on the move.
How do you handle deployment to the Apple App Store and Google Play?▼
We manage the complete end-to-end release lifecycle. This includes configuring automated build pipelines (such as Codemagic), provisioning signing certificates, ensuring compliance with strict store privacy guidelines, and successfully publishing your application to both public stores.
