Incorporating Feedback Lesson 5 0

Check-in: paper prototype By now, your paper prototype should be complete, so that you can begin creating your app 1

Agenda Topic Databases Testing your app and incorporating feedback Activities General app improvements feedback Interface feedback 2

Databases Organized collection of data Intended to organize, store, and retrieve large amounts of data easily Examples: iTunes is a database for all your music Google has a database of websites which is used for Google Search Facebook is a database of people 3

Databases in App Inventor If you want to save data after the application is closed you must use a database TinyDB stores data directly on the phone and will only be used by that phone TinyWebDB stores data on a web database that can be shared among phones 4

Data Key – label for what’s inside Value – data that’s inside We use the Key to look up the Value in the database Example: Phone Book (a database of contact information) Key = name Value = phone number 5

How can you use a database for your App? 6

Incorporating feedback: Making your App Better Feedback from potential customers will… Tell you if your solution (app) to a problem is accurate Suggest improvements that can be made in the design of the app Suggest other features to add (either now or in the future) 7

Activity: Usability Testing Test your paper prototype Give feedback about the other team’s user interface Take notes on the feedback that you receive Record your ideas in page 17 of the workbook 8

Activity: Incorporating feedback (15 mins) Incorporate any helpful feedback you receive by revising your paper prototype Make a plan to complete the updates Record your ideas in page 17 of the workbook 9

Activity: Create Prototype Skeleton (45 min.) Use your paper prototype to develop a skeleton of screens in App Inventor: Make and name a screen in App Inventor for each screen your app will have “Screen1” must be your welcome screen! Include all critical transition buttons (naming each one appropriately) that will take you to another screen. 10

Task List Finish incorporating feedback into a final paper prototype Finish your skeleton of screens in App Inventor Next week before class: Implement all the transitions in the blocks editor to help the user move from one page to another 11
