Right now it only lets you enter Credit Check Total and Credit Karma because that's what I use and I don't know what the other pullers offer.
You just enter your CCT Equifax, Experian and Transunion FAKO scores and it will show you your FAKO average. It will also show you what scores changed and by how much. A positive change is displayed in BLUE and a negative change is is RED.
With the Credit Karma it does the same thing but does not show an average.
Plans for the next revision
1) Average Credit Karma and Credit Check Total by months
2) Add in other daily pullers as suggested
3) Anything else the community can think of that I'm able to do.
