Good job @jwolf for finding this product.
Now for my pros and cons below :

Pros :

• A very easy to use application which can really help generate real time reports on how much you have used your phones with those applications. This reports can be exported in either CSV or Excel file.
• It can keep data up to 2 years which is a big advantage when looking back into some analysis. It can also create periodic summary reports like hourly, daily and weekly which can be really important too.
• You can customized the settings according to your set activities.

Cons :
