Dear Socially Stephanie:I'm currently working on an app. While the launch is still some time away, what should I be doing to prepare? I want to get as much excitement around the app as possible before the launch and then go hard once it launches to make sure I get a lot of downloads from the get-go. Do you have a strategy I could follow? I'm planning to introduce it on Google Play and iTunes.App-tastic in Apple Valley Dear App-tastic: Congratulations!...
