You need the Suunto Movescount application and a cable to sync the device with your PC. However, it's not specified if you can sync it with an iPad. On the same page it's specified that the device is compatible with the Suunto Apps.
You can browse them through the following link: http://www.movescount.com/apps
However, it's not specified if it supports iPad or not. I've checked all the categories and areas from its official website, but there was nothing available.
