Where can I find lead tracking software?

Hi. Need some advice!!!!!
I want to read reviews of companies that offer the right software to guide potential customers. This is very important to me. Here I found a website that has reviews on it, well, like Apptivo. You can read about https://leadmanagement.reviews/apptivo-com-lead-management-review/ there. What do you think about this site? I would appreciate the reviews.
