Info-trackers, quant-selfers and all-round personal data bods – whatever you call them, more of these people are using activity-measuring devices and apps to help improve the way they live. Calorie counting suddenly looks pretty old school. And, with the Olympics a mere week away, we thought we'd put some focus on personal performance.

We invited three esteemed speakers to help us look into how devices, apps and data can transform – and improve – the way we live and perform.

Martin Blinder, founder and CEO of soon-to-be-launched personal analytics platform Tictrac led the way. His site aims to be the hub for all the data you generate – from running and calorie trackers, to social media or sleep monitors. Once complied you will then be able to make correlations and uncover patterns: Does your calorie intake spike when your inbox does? Or do you run further when it's raining?

Michael Forrest looks to help people better understand a wider issue – of Happiness. His app Happiness acts as a digital journal for mood – at random points in the day asking how you're feeling, then asking for a happiness rating and a reason. Through consistent usage, the aim is to identify patterns and better understand your emotions.

Co-founder of Six to Start, Adrian Hon part of the team who created phone app 'Zombies, Run!' He talked about how his narrative-based running app is motivating people through simulated zombie chases, and the power of story in conquering inertia.

After the presentation there was a panel discussion with some thought-provoking questions from the audience. The audio from this we will be up on our Forum page in the next couple of days, so check back in to listen to the discussion, and scroll down for images from the night.
