How We Build Cross-Platform Apps

STEP 1

Initial Consultation

We begin by discussing your project goals, vision, and requirements. This step helps us understand your business objectives and target audience. It ensures we have a solid foundation to deliver an app that aligns with your strategic goals.

STEP 2

Platform & Tech Selection

We select the most suitable platform and tech stack. Our experts help you choose the right solution, prioritising compatibility with iOS, Android, and the web. We often choose Flutter but also utilise other frameworks if they fit better. During this phase, we describe the high-level solution architecture and make a C4 diagram.

STEP 4

Development & Integrations

We develop your app using the selected technologies while ensuring smooth integration with third-party APIs. Throughout the process, we focus on performance, scalability, and security. We work closely with you to ensure the app is delivered on time and meets all the expectations.

STEP 5

Mobile QA Testing

Our testing phase ensures your app performs optimally across all platforms. We have a Test Device Lab that consists of a wide range of devices covering different OS versions, platforms, sizes, types, and manufacturers, to ensure your app runs smoothly on all of them.  This stage helps us identify any issues and fine-tune the app before launch.

Deployment & Support

We manage the launch on Google Play and the App Store, ensuring all requirements are met. After your app is live, we provide ongoing updates, feature improvements, and performance monitoring.
