Our Process to Develop iOS Applications

Research & Development

Research & Development

Once the necessary inputs are taken from the client, our iOS app developers start researching for developing the concept of the application. In order to ensure the innovativeness of the end product, R&D is something that becomes tremendously vital. In this phase, the necessary resources of the project are detected along with their source. For instance, we determine the type of programming language which would be used for developing the app.

Design Phase

Design Phase

A wireframe and physical model of the iOS app is developed in this phase, using the logical model which has been developed in the analysis phase. The physical model of the app contains the database schemas after detecting the relationships, business object logic, and many more. The design is sent to the client for approval and being carried forward to the development phase once it is approved.

Coding/development Phase

Development Phase

In this stage of our iOS app development process, our developers come into the scene and write the codes for the individual elements or objects of the application’s physical model. Then we move towards a fully functional and working application by gathering and embedding the system objects which have been developed. Hereon, the embedded application is hosted on a server for the purpose of testing.

Testing Phase

Testing Phase

Our testing process comprises of three different levels, namely, Element Testing, Prerequisite Testing, and Approval Testing. While we do the element testing, each of the components is tested in order to make sure that they are in line with the physical design of the iOS application we are developing. After ensuring the appropriate operation of the system as per the design, the application is tested according to the requirements gathered during the requirement phase of the development.


Deployment Phase

There are two different levels that we include in our deployment phase – a three to six-month pilot testing and the actual deployment after the pilot testing. At the end of the testing phase, we place the iOS application on the server which will make the app live and accessible to the users. Afterward, the user guides are delivered, users are trained and the system control is handed to the client.



After the completion of the iOS app development, our job does not get finished. It just gets started! We offer free technical support for your iOS app for some specific glitches. We monitor your app on a regular basis. Any bug or designing glitch gets fixed in this period of time without any additional cost. We tend to make our clients happy and satisfied with our service and performance.
