How We Work

Our App Development Process

A proven 4-step framework that ensures your app is delivered on time, on budget and exactly to spec.

1

Discovery & Planning

We deep-dive into your vision, target audience, and technical requirements to create a comprehensive project roadmap. User stories, wireframes and tech stack defined here.

2

UI/UX Design

Our designers craft pixel-perfect interfaces with interactive prototypes. Every screen is designed for maximum usability, engagement and brand consistency before a single line of code is written.

3

Development & Testing

Agile sprints with weekly demos keep you in the loop. Rigorous QA testing across 50+ devices — performance, security, and edge cases all covered before launch.

4

Launch & Support

We handle App Store and Google Play submission end-to-end. Post-launch, our support team monitors performance, fixes bugs and rolls out updates so your app stays ahead.

RSFSOFT LTD has done great work for us. We will continue to use them for our marketing. For our website they hooked in an API that I know takes above average skill to complete and make it work right. All works great.

Zara and Faizan are excellent. I built my business website with them two months ago, and whenever I need something, they fix it right away. If anyone wants to create a business website, they are highly skilled.

FAQ

App Development Questions Answered

Everything you need to know before we start building your app together.

Timeline depends on complexity. A simple MVP app typically takes 6–10 weeks. A full-featured consumer app with multiple integrations takes 12–20 weeks. An enterprise-grade app can take 4–6+ months. We provide a detailed project timeline during the discovery phase so you always know exactly when you'll go live.

This depends on your target audience. If your customers are primarily in the UK, iOS first is often preferred since iPhone users tend to have higher purchasing power. If you're targeting a broader global audience or emerging markets, Android has a larger market share. We often recommend React Native or Flutter for new projects — one codebase, both platforms, significant cost savings.

App development costs vary significantly based on features, platforms and complexity. A basic single-platform app starts from £4,999. A cross-platform app with standard features typically ranges from £8,000–£25,000. Complex apps with custom backends, advanced features and multiple integrations can range from £25,000–£100,000+. We provide a fixed, all-inclusive quote after the discovery call — no hidden costs, ever.
