We were looking to revamp our application. We had worked with another developer, and the quality was poor. We found a few companies on Clutch, and felt this team had the best proposal within our budget.
They restructured the frontend design of the app, and added functionality. They changed the look, and the signup process. One of the features they added was the ability for users to add friends and compare stats. The logistics and look of the design were the main focus for changes. They changed the coding from PHP to a very complex, more modern coding language. They also developed a backend portal that allows us to analyze the users.
They're very coherent and transparent in what they do. It is a good working relationship. They work in an Agile environment. They do a good job of including the client in their process and go through reviews. Communication has been pretty good.
