App to track inquires from/to prospective tenants?

[Karen Dayley]

I have been finding it difficult to respond to and keep track of all the phone calls, emails, and texts I am getting from prospective tenants that are responding to my apartment advertisements.  The rental market in my area has picked up tremendously and I used to get just a few phone calls/emails a day but now I'm getting 25 or more per day. I don't have time to do phone interviews any longer and to schedule individual showings. I have been setting up open houses and struggling just to respond to all the inquiries with dates and times of the open houses.  I would like an app to record the names and phone numbers of calls/texts/emails that I am receiving, what apartment they are interested in, record that I have responded to them, and if they are confirming a showing or if they will be attending an open house. Does anything like that already exist? How do others track prospective tenant leads  and responses?
