Gather Requirements

On our call, we discuss with you the need to develop the iOS app, the result you want to achieve, the features you want to integrate, the country you want to target, and the outcome you are expecting from your iOS app. Once we understand your requirements, we validate the idea and define a roadmap to proceed further.


Wireframing and Designing

Once we understand your idea, our BA team wireframes your iOS app to know how your app communicates. After completing the wireframe, our UI/UX team designs your app with the perfect color gradients as per your color preferences. We use Adobe XD tool to wireframe and design the project.



Once you approve the design, we start to develop the iOS app using Swift, Objective-C, or Dart language as per your requirements. Before starting, our project managers define milestones for the project delivery. We take your feedback at every stage and work on it in case it is not as per your requirements.

Quality Testing

Quality Testing

When the iOS app development gets completed, our QA team writes the test cases to understand the functionality of your iOS application. We perform different tests including unit, functional, speed, and performance testing as per your project requirements, and ensure that the application is bug-free, responsive, and tested across multiple devices.

Solution Deployment

Solution Deployment

After the testing is completed, we deploy your iOS app solution on the App Store as per Apple’s guidelines. In case there is an error during publishing, we work on it and make a rollback plan. We take care of the entire deployment process and even provide you with 3-months of post-release support for free.
