Real estate investor's automated software or app

[Emmanuel Zizi]

I'm brand new to real estate investing. I don't know if I must have a paid automated software to succeed or not , but the many good things I've heard about automated lead generation software make it seems that it's a very valuable tool. I am looking for a software or app that can make it easier for me and help minimize mistakes.

I would like to know which of the software is best. i have been reading on the following softwares: Profit Grabber from Marko Rubel, IFLIP from  Cameron Dunlap, Lion Desk and REIPRO.

Please, let me know if i really need a paid software or not and if so , what is your recommendation.

Thank you
