Your job for this discussion board is to choose a developmental period and design an app that would apply to them. It could be a game, a self-help app, a parenting resource app, etc. The possibilities are endless. For your thread:
-  Describe your app. What is the purpose? How does it work?
-  Identify the target audience for your app (i.e., who you would want to buy and download it).
-  Discuss key developmental markers or characteristics for that age group (include textbook citations).
-  Pretend you are trying to get a group of developmental psychologists to invest in the production of your app. 
-  Discuss why your app is developmentally appropriate and be sure to "sell it."
Replies: For your replies, you will critique 2 of your classmates' apps. For each reply:
-  Identify 2 strengths and how they relate to developmental psychology.
-  Identify 2 additional areas of development to consider for that age group. What else might the app address? What might it be overlooking?
-  Support your critique of areas of improvement with citations from the textbook.
