Frequently Asked Questions

Application Development โ€” FAQ

1. Can you manage app store submission and release for UK audiences?

Yes. We prepare metadata, screenshots, privacy details, and build pipelines, then guide submission to Apple App Store and Google Play. We work within GMT business hours for reviews, and invoices are issued in GBP.

2. How do you handle GDPR and privacy prompts inside the app?

We implement clear consent flows, privacy screens, and data-minimisation patterns aligned with GDPR expectations. Where relevant, we set up SDKs (e.g., Firebase, AppsFlyer) with consent controls and document what data is collected and why.

3. How long does it take to build a mobile app?

A small MVP typically ships in 40โ€“45 days; medium apps in 8โ€“10 weeks; enterprise builds are scoped individually with milestone-based delivery.

4. Do you build for both Android and iOS?

Yes. We use Flutter for cross-platform delivery and native Kotlin/Swift where performance or platform APIs demand it.

5. Who owns the source code?

You do. Full source code, store accounts and cloud infrastructure are handed over on final payment.
