This app may not seem like much at first glance, but it is a little treasure. It does exactly what it claims to be able to do and does it superbly. I find it invaluable for keeping an eye on system data, particularly cpu load and temperature. I also like the fact that it lives inside your menubar because it makes so much easier to access quickly. The developer has had this app in the store for a while now and he/she is constantly maintaining/updating it. I consider system pal to be one of my must-have apps.
