Technologies Used

SvelteFirebase

Need to reach both iOS and Android users without doubling your development budget? Building with Svelte lets us create apps for multiple platforms from a single codebase, significantly reducing time and cost.

Why Choose Us

We know when cross-platform makes sense and when native is better. One codebase covers iOS, Android and web, which usually means a shorter build and lower cost than separate native apps. We help you make the right technology choice for your specific needs.

Frequently Asked Questions

Which framework do you use?

We build cross-platform apps with Svelte, using Firebase where the app needs it. We'll recommend the right approach based on your needs.

Will users know it's cross-platform?

Not if it's built properly. A well-built cross-platform app looks and feels at home on each device.

What about platform-specific features?

We can access most native features from a single codebase. For very specialised iOS/Android features, we can add native modules.
