Good Afternoon @daltornia,
The SteemFollower app is a free service that you gain "points" for your upvotes. Theses points can be used to enhance your voting power and/or get you more upvotes and visibility. If your points are zero ,you do not have visibility on the platform. Also, if you have not vote 5 times in a 24 hr period, you also will have no visibility.
The program itself costs nothing, unless you want to buy points to get more points and more visibility. I bought 10,000 pints recently for 1 STEEM, and I'm getting about 15-20 upvotes a day on my posts through SteemFollower.
Thank you very much for clarifying my doubts! It's a great help
No problem. It is a fantastic program!
