Upgraded to 2.0

Great program! Monitors CPU temp (high, low, avg, etc.) and allows 2 levels of high temp alarm via text and/or audible alarm. Vers. 2.0 is updated for Mountain Lion and adds Fahrenheit degrees option. You must, however, update from the Aladdin site by making a request thru customer service. The good news is C.S. responded within minutes for me.

Perfect in it's simplicity

This is exactly the app I was looking for. I didn't need an app that monitors every conceivable system metric - just needed the temp. When cutting video, my Macbook Pro runs hot with the lid down when hooked up to an external monitor, which means I have to run a cooler fan underneath. This little app tells me when to turn it on. So far it works like a charm.

Quick response, upgrade coming soon

Popular request was to include a fahrenheit reading, which they are including in their soon to be available upgrade.
