When you press the START button you cycle through a list of strings and a set of images with the help of a clock.
The song happy birthday start playing after pressing the button. This is often advised to listen to or sing it twice because that woudl be the time you should use to wash your hands.
Great guide as always, Peter!
I was thinking of making a similar app a few weeks ago but never got around to it. Perhaps someone here might be interested in turning this idea into an app…
The goal is to let the user prevent touching anything after they’ve washed their hands. In all the apps I’ve seen so far, the user has to touch their phone’s screen to close the app and then put their device away (maybe in their pocket). Phones are usually contaminated, and touching them after washing hands undoes any sanitisation.
What if the user could open the app, start the 20s timer, and put the phone in their pockets immediately? The player component could be used alongside the phone’s vibrate functionality to give haptic feedback to the user. Once the timer us up, the screen is automatically locked (perhaps using the keyguard component).
It’s an interesting idea to look into…
