Hi, that's because you're marketing it all wrong. I checked out your app and the free content doesn't seem compelling enough to want to pay for the rest.

Your messaging is all over the place trying to target every possible audience within the college environment. An app like this should be native. Look for ways to couple college living with tips and answers that would benefit students.

Pick channels and stick to one goal/audience per channel.

Today's marketing is not about throwing ads at people and expecting growth.
Ask yourself -
How can I efficiently reach and had a conversation with my customers?
How and where can they best reach me? My services?
How and where can I facilitate my customers/users reach each other? (Promote word of mouth?)
