Our Mobile App Development Process

We follow a structured, transparent, and agile development process that keeps you informed and in control at every stage — from the first conversation to the final app store submission. Mobile App Development Process by BitByte Innovations

1. Discovery & Strategy

We start by deeply understanding your business, your target users, and your goals. We document your requirements, define the app scope, map user journeys, and create a detailed project roadmap and timeline.

1. UI/UX Design & Prototype

Our designers create wireframes and interactive prototypes for your review before a single line of code is written. You see exactly what your app will look and feel like, and we refine it until you are 100% satisfied.

1. Agile Development

We develop your app in short, focused sprints (typically 2 weeks each). You receive working demos after every sprint and can provide feedback continuously. This ensures no surprises at the end.

1. Quality Assurance & Testing

Our QA team tests every feature on multiple real devices across different screen sizes and OS versions. We conduct functional testing, performance testing, security testing, and user acceptance testing before any release.

1. Deployment & App Store Launch

We handle the full App Store (Apple) and Google Play submission process, including listing optimization, screenshot design, and keyword targeting to maximize organic downloads from day one.

1. Post-Launch Support & Growth

After launch, we monitor your app’s performance, fix any issues quickly, and plan the next feature releases based on user feedback and analytics data.

Frequently Asked Questions About Mobile App Development in Bangladesh(FAQ)

How much does it cost to develop a mobile app in Bangladesh?

App development costs in Bangladesh typically range from BDT 80,000 to BDT 10,00,000+ depending on the app’s complexity, number of features, platforms (iOS/Android), and integration requirements. At BitByte Innovations, we provide a detailed, itemized quote after a free discovery call so you know exactly what you are paying for with zero hidden surprises.

How long does it take to build a mobile app?

A simple app (3–5 screens, basic features) typically takes 4–8 weeks. A medium-complexity app (10–20 screens, backend integration) takes 8–16 weeks. A complex enterprise or multi-platform app can take 4–9 months. We always provide a realistic timeline before the project starts.

Do you build apps for both iOS and Android?

Yes. We develop native iOS apps (Swift), native Android apps (Kotlin/Java), and cross-platform apps (React Native, Flutter) that run on both platforms from a shared codebase. We will recommend the best approach based on your budget, target audience, and feature requirements.

Will I own the source code of my app?

Absolutely. Upon final payment, you receive full ownership of the app’s source code, assets, and any accounts created for the project (App Store, Play Store, backend servers). We believe in 100% transparent IP ownership.

Can you update or improve an existing app we already have?

Yes. We frequently work on apps built by other developers. We conduct a code review first, identify issues, and then proceed with improvements, new features, or a full rebuild, depending on the state of the existing codebase.

Do you provide support after the app launches?

Yes. We offer flexible post-launch maintenance packages covering bug fixes, OS compatibility updates, performance monitoring, and new feature development. We recommend all clients budget for at least 3 months of post-launch support.

Can you integrate local payment gateways like bKash and Nagad?

Yes. We have experience integrating all major Bangladeshi payment gateways including bKash, Nagad, Rocket, and SSLCOMMERZ, as well as international gateways like Stripe and PayPal. We handle the full integration including sandbox testing and live go-live.
