Application development from A to Z

Step 1
Plan and Mock-up
After consulting with a client, we move to mock-up creation that would describe the look and feel of each mobile app page. This phase allows us to have a detailed work breakdown structure and plan agile sprints for a dedicated team accordingly. Each slightest change in the mock-up correlates with the client's feedback.
Step 1
Step 2
Development and Testing
When we deliver MVP, our engineers go ahead with application development. Sprints allow getting feedback from the customer after every phase and implementing improvements, if needed, into the project. When the app is ready, it gets on the hands of testers who make it a bug-free product.
