A window into your computer's soul
Linking to your computer over a shared network, the app displays your system performance. Live monitoring shows a ton of stats, including the current GPU usage, fan speed, and even internal temperature - perfect for deciding your next upgrade.
Other functions include a game list, and remote control of media functions (including volume).
It's a bit of fun, but only really for tech heads.
