Projects start without a clear picture of features, timeline or real cost.

BUILDING AN APP IS RISKY WITHOUT A PLAN
Most apps fail before they ever launch properly.
A good idea is not enough. Apps need clear UX decisions, the right technical foundation, realistic scoping and a launch plan — or they end up over budget, late, or abandoned by users after the first open. Your app needs to be fast, stable and genuinely useful from day one.
See our app development process →Downloads without retention
Users install the app but drop off due to slow performance or confusing flows.
Wrong platform choice
Native vs. cross-platform decisions made without weighing cost, speed and long-term needs.
Store rejection & delays
Submission issues, missing guidelines compliance or backend gaps stall the launch.
THE RUBITCUBE APP DEVELOPMENT SYSTEM
Every stage needed
to ship a great app.
We do not treat app development as a single build phase. Discovery, design, engineering and launch work together around your users and business goals.
01
Discovery & product strategy
User research, feature prioritisation, technical feasibility and a focused roadmap aligned with your users, timeline and budget.
- User & competitor research
- Feature scoping & prioritisation
- Platform & architecture plan
02
UX/UI design
Wireframes, user flows and interface design built around clarity, accessibility and conversion, tested before a single line of code is written.
03
Native & cross-platform development
iOS (Swift), Android (Kotlin) or cross-platform builds with Flutter and React Native, chosen to match your performance needs and budget.
04
Backend & API integration
Secure APIs, cloud infrastructure, payment gateways, push notifications and third-party integrations built to scale with your user base.
05
QA & device testing
Functional, performance and usability testing across real iOS and Android devices to catch issues before your users do.
06
Launch & ongoing support
App Store and Play Store submission, post-launch monitoring, updates and feature improvements based on real usage data.
WHAT SUCCESS LOOKS LIKE
Less guesswork. More apps that people keep.
Our work is designed to improve the complete journey from first open to daily use, not download counts alone.
✓
A validated feature set scoped around real user needs, not guesswork.
✓
A stable, fast app tested across the devices your users actually own.
✓
A smoother onboarding flow that keeps users past their first session.
✓
Transparent reporting showing completed work, progress and next actions.
SELECTED APP WORK
Proof built through
consistent execution.
Every app has different users, constraints and timelines. These examples show how a structured approach turns an idea into a stable, well-used product.
4.7★
average rating
after launch
after launch
A cross-platform booking app rebuilt for speed and clarity.
CHALLENGE
Replace a slow, high-drop-off booking flow with a faster, more intuitive app experience.
APPROACH
UX audit, streamlined booking flow, Flutter rebuild, backend optimisation and staged device testing.
OUTCOME
Booking completion rate improved and the app maintained a 4.7-star average rating after launch.
One app codebase adapted for multiple regional markets.
A coordinated build covering localisation, multi-currency checkout, regional payment gateways and staged rollout for the UK, Saudi Arabia, Qatar and wider Middle East markets.
App outcomes vary by scope, platform, integrations, market and implementation speed. Past performance does not guarantee identical future results.
WHAT YOU RECEIVE
Clear work.
Clear reporting.
Your project stays understandable. We document what was completed, what changed, what requires client action and what happens next.

FREQUENTLY ASKED QUESTIONS
Before you begin.
Clear answers about the approach, timeline and expectations.
Ask another question ↗We build native iOS and Android apps as well as cross-platform apps using Flutter and React Native, depending on your budget, timeline and performance requirements.
Timelines depend on app complexity, number of screens, integrations and platforms targeted. A typical MVP takes 8 to 16 weeks from discovery to App Store submission, which is why we scope every project after a discovery phase.
Yes. We can audit, maintain and extend existing native or cross-platform apps, including performance fixes, new features, UI refreshes and backend integrations.
Yes. The plan includes user-flow mapping, wireframes and UI design. The final number of screens and design depth is confirmed in the proposal based on app scope.
Yes. We prepare store listings, handle submission requirements and support you through the App Store and Google Play review process until launch.
