Made with passion since 2007

RaceChrono app started its “life” in early 2007 as a fun hobby project for my new Nokia Series 60 phone. Fast forward major milestones: Top 10 app in Nokia’s Ovi Store with over a million downloads (2009), RaceChrono app for Android (2012), RaceChrono Pro for Android with video functionality (2014), and featured app for Tag Heuer Connected watch (2015). And now in 2017, introducing RaceChrono Pro for iPhone and iPad!
