The Brief

When CCleaner approached Novoda they were looking for an app development agency that could help them meet the high standards their customers expected.

Their brief to us covered these key features:

  • Simple user-focused app that cleans your device and makes it faster, no unnecessary bells and whistles
  • Provide a high quality service in multiple countries and languages, ensuring a flawless layout for all
  • Run seamlessly across any device, including more basic models with less storage space, which are able to run better and last longer by using CCleaner
  • Introduce a freemium model with in-app-purchases, without diluting the experience for free users

We needed experienced Android specialists. We shortlisted a number of agencies, but Novoda stood out because everyone else was more about building basic client–server type apps. The nature of our application meant we required someone who really understood the Android platform at a system level.

Our Approach

  1. Our first step is to get to know the end-users, so we conducted an in-depth user study to better understand their needs and motivations.
  2. We welcome close collaboration with our clients, so we held regular workshops with the team at CCleaner to discuss new ideas and shape them into useful features.
  3. We rigorously test every possible user flow across multiple devices to ensure perfect functionality in every scenario.

It’s been a great journey so far, working with enthusiastic and skilled people. Sometimes the easiest things are the most difficult to achieve and you can only do so with a great team.
