Platform or Tool to crunch numbers for real estate

[James Bond]

Hey Everyone,

Have been using an Excel file to crunch numbers and understand cash flow to decide on investments, but been getting a little tired of keeping track of all these files and then changing numbers on them. Was looking to see if there is a platform in the market allowing me to crunch numbers and keep track of my investments, I know BiggerPockets has calculators but want to know if there are any other better tools out there! 

 Any information is appreciated! Thank you!
