We're creating an app you can download to a device that educates and guides our target market (seniors) on how to use technology and social media. So our app will focus on seniors, which is a major customer segment you should focus on, and also anybody else who struggles with understanding and using technology and social media apps.

I Need Customer segments and key metrics on this topic

With the key metrics you're in charge of coming up with the rate that we will charge people for the full version of our app. Our plan is to give every consumer a one week free trial and then once the week has ended they only have access to limited resources and instructions. You're the one who determines how much we should charge people for the full version, and that's how we'll make our sales. So you need to do some research to see if there's anything else like this at all and see what they charge, and also take into consideration factors that may influence how much seniors are willing to spend on the app
