When I plug in results on my app using my phone my CSI shows -0.34 however if I log the same results into the website for the PoolMath the CSI shows -0.24.

Maybe not a big deal but wonder why the same number produce different results ? There is another web site that you can plug in your numbers and it also shows -0.24 so it appears the phone app is the one off ?
 
I suspect you have a 0 in Salt level in the Webpage one. The App assumes you have a minimum salt level of 1000 ppm when you are NOT tracking Salt. If you turn on the Tracking Salt, and enter 0 for salt, it will match the webpage.

No pool has 0 salt.
