    • Pages Jaunes
    At Solocal, we are committed to providing the best experience to our users. We are convinced that this requires the development of high-performance, fast-moving and energy-efficient applications. These constraints are paradoxically contrary to our desire to offer more and more features to our users. By integrating performance and energy consumption measures at the earliest in our development cycles, we continuously monitor the impact of each change. In this sense, Greenspector helps us to think differently about how we develop and change the culture of our developers.

The final goal was to either reduce the energy consumption of the app, or improve its performance, or both. The team has succeeded in a very short time frame, and above all they have shown that it was possible to go way further.
