Ok, on the constructive criticism front... The fun facts section of the app description sounds kinda weirdly... cold? Considering it's not really building on your app, that seems bad. It feels too "Science facts", and less "romance facts", which is more what I think you're looking for. I think a lot of people will feel uncomfortable being told how fast they get off or how they like to get off based on their gender, especially when you're trying to sell something to them to do that exact thing. :)
