This is the HelloPurr app. I followed the tutorial and found it very simple. I customized this app by first using my cat’s picture.
This took me about 10 minutes to make the actual app. It took a while to figure out how to get it to my phone. I immediately emailed the app to my wife, she loves having her cat with her now.
Then I spent several hours adding and changing the app. Mostly just messing around to see what kind of stuff I can do on App Inventor.
This version of HelloPurr, also has an added button to switch to a different screen. You can take a survey on the second screen and then return. The results are meaningless and go nowhere, I just wanted to mess around with multiple screens.
