It's tempting to think we know what's best and what features users will want in your app but most of the time, this isn't the case.

This is a great time to start engaging with your potential users or fan base. Get them to input into real world features they would like to see in your app.

Use your existing list - If you have a list of current clients, why not send out an e-mail asking for ideas on your new app.

Use social media - Get on Twitter and your Facebook Page and reach out to your primary audience.
