Cloud Servers & Mobile Devices


While it wasn’t essential that the students understand everything going on in the background to design the app, it was important that they at least realize there’s stuff behind the scenes that make all this magic work.

I broached the subject by discussing how they would find their friends on the app, to share lists, and comment on each other’s lists. We had to go through the entire process of inviting a friend to see your list. Most of the students were familiar with Instagram, so they had a general idea, but they never thought about the step-by-step process:

  • If the friend has the app…
    • Search for the friend’s username, or enter the friend’s username
    • Have the app send an invitation to your friend that you want to be “friends” on the app
    • Have your friend accept or reject the invitation
    • If the invitation is accepted, add that friend to your list of friends
    • If the invistation is rejected, don’t add that friend
  • If the friend doesn’t have the app…
    • Contact the friend online to get the app
    • Make sure you tell your friend your “username”
    • Wait for the friend to install the app, and “friend” you (as above)

The students came up with several ways to contact their friends online: email, texting, Skype, TextFree, WhatsApp, Instagram, Kik, and several ways offline: phone call and speaking with the friend face-to-face. I will implement that feature over the next few days.

I asked the students to come up with more app names, since the last set of names were mostly taken, and asked them to start designing an icon for the app. Some of the students are very artistic and the result would be very cute if we could use the icon they create.
