I recently got a review for Temperature Guard from a guy complaining about too high memory usage. The review is in german, so I will not post it here. Well he complains that this app uses 250 mb of his smartphones memory, so he uninstalled it.
I was a little bit shocked and investigated this case. Temperature Guard Free & Pro will use about 30-75 mb of your memory, what is quite okay in my opinion.

Another thing about memory usage of apps is, that memory is made to be used. Unused memory is worthless. The android subsystem will handle memory usage, garbage collection and many more.
