We now have a place to sign up to be notified about beta and launch information. We are just using a simple google form to collect email addresses and location information so we can quantify who is interested in our app, and where are they from. If we can't get 1000 people to sign up, we are going to look to pivot / re-evaluate on our idea. My thoughts are your app idea is fundamentally flawed if you can't get a significant number of people to sign up to be notified when its released.
