The app's also attached to the 1st post of this thread - try downloading it from there.

I have updated the app in the first post to add information about lateral weight transfer.

Here's the theory, as I understand it.
As you corner, there is lateral weight transfer, so the tyres get loaded and unloaded. There's not a great deal you can do about the weight transfer - it's going to happen. What is important for the handling and balance of the car is the amount of weight transfer at the front and the rear, or in other words, the roll stiffness. The larger the lateral weight transfer at either end of the car, the more total grip that end loses.  A more balanced car will have a similar amount of weight transfer front and rear - you want both the front and the rear to lose around about the same amount of grip to maintain a balance.

So the app shows two numbers, both related to how much more lateral weight transfer there is at the front compared to the rear. The bigger the number, the more weight transfer is happening at the front compared to the rear. If the number is negative, you are getting more lateral weight transfer at the rear. The "Corner" figure shows this for the last corner, and the "Avg" figure shows this averaged over the whole lap.

A stiffer end has more lateral weight transfer. So if you want to get a positive number that the app displays closer to 0, soften the front or stiffen the rear. If you want to get a negative number that the app displays closer to 0, stiffen the front or soften the rear.

A good car to experiment with is the Ferrari 599XX Evo, as that has a big range of ARB adjustment.

Just to clarify, of the two numbers one is lap average, the other last corner?
I'm getting around 100 for the top number and around 0 for the lower but not understanding why they are so different??
(I'm in the ACL Mclaren M8C)

Yep, one's lap average and one's last corner only. Is the Average 0? Maybe it's possible to get 100 for one corner, but average of 0 over the whole lap (if some corners are negative)? Is it always 0, or does it change?

Just did a few laps in the lotus at QLD, and got around 350 for Corner and around 180 for Average consistently
across a number of laps.

Yeah, you don't have enough ARB adjustment in the Lotus to really balance it, but you can improve the weight transfer distribution.

Does the 'corner' reading change through the corner?
I saw some high figures there and assumed that it was the 'last' reading, ie. corner exit only, as I was looking at the apex during cornering and not the app.
