“For people who love graphs about CPU usage history, it’s great – though not brilliant. Everyone else: move along.”£2.99
If nothing about the idea of monitoring the vital statistics of Macs, PCs and Linux boxes appeals to you, move along. But if you want a quick, easy, beautiful way to see what your computer is up to – because it’s an important file server, or you’re just interested – get iStat 2.
CPU, network, memory, disk status, temperature sensors and more are displayed both as figures and in handy graphs; tap some sections to see data going back for up to a year. Annoyingly, you don’t get data about which processes are using the displayed resources.
You can connect to computers over the internet, though you need to fiddle with your router; we’d prefer a middleman service to make it easier. (It does use iCloud, but just to sync servers between devices.)
You can also get stats for your the iOS device the app is running on – though they’re not as detailed.
