The Runtastic app lets you easily track your runs and fitness activities. With over 100 million users, it’s the most popular running app for smartphones, as well as being the best-selling app overall in multiple countries.

My role and the team

Running ahead of the competition

Health and fitness is an extremely competitive space for mobile apps. In a team of four, I was one of the two designers who mostly focused on the Android version of Runtastic. I was also involved in cross-platform user research and user experience discussions, as well as producing designs for A/B testing on iOS and assets like icons and illustrations. We were constantly working on the Runtastic app to further refine the UX and polish the UI, to keep the app an industry leader. Note: in September 2019 the app was rebranded and is now available as Adidas Running by Runtastic.


Award-winning design

Shortly after I started working at Runtastic, the company launched the Material Design overhaul of the flagship app. In the following months, we received some feedback from Google and I took the responsibility of redesigning some of the screens as well as designing some news ones. The newly introduced running leaderboard, for example, added an important social element that significantly increased user engagement.

Following these updates, the Runtastic app for Android was included in the Editor’s choice collection and was one of the 15 apps included in the Material Design Showcase at Google I/O 2015.

Icons and illustrations

Finding a consistent voice

Runtastic’s imagery was quite inconsistent when I joined the company. During my time there I produced many illustrations, mostly to be used in the apps, and I led the team effort to find a new style that could be easily used by everyone in the team in a consistent way.

This tileable pattern for backgrounds was one of the distinctive elements of the new illustration style.

In addition to this, I also designed the next evolution of the Runtastic icon set, optimizing the icons on the pixel grid and using consistent visual traits across over 100 icons.

More love from Google and Facebook

In the Spring of 2015 Google UK launched a campaign for Android with the slogan “Be together. Not the same.” Runtastic had a huge featuring in this, and I worked to provide assets for printed billboards,, promotional videos, and more.

The Runtastic app was also featured in the “Build better” video series by Facebook, for the F8 conference in 2015. The video tells the story of rapper Masta Ace, and shows how Runtastic is part of his life and the lives of many other people around the world.
