As basic as it can be described you changed the amount of force required to lift a weight on a simple lever with the fulcrum being the wheels.
Yes..for sure it lowers the over all CG in this case at the front of the car.
I would also add the following
1) since the weight was added at the front of the car this will make the car slide more at the front (i.e. push) when near the limit and actually cause more oversteer when not near the lateral limits of the tires (a good example can be the middle of a slow tight corner)
2) Reducing traction rolling has a lot to do with getting both ends of the car to roll into the carpet the same amount. if the car was traction rolling because the front of the car would would not roll into the carpet as much as the rear, then adding the weight can help this.
3) In general I don't recommend adding weight to the car unless you are under the min weight limit, as additional weight will ultimately produce less lateral grip, less acceleration and less braking = slower laptimes.

Good call. That danger was the reason I did not do this when I was younger...but as I got older, I still wanted to do it, and figured if I don't do this now I will never do it.

In rare and extreme cases this is a route to take. I used to do this before I figured out other techniques to reduce traction rolling. The issue with glue is that is too difficult to add a consistent amount of glue on each tire, and the glue comes off...making it a long day of chasing setups.

Yeah..it was not available on the apple store for a while, because I was not aware you needed to buy a developer license every year to be able to sell an app on the app store. So it was not available for a few weeks late in 2013.
