For the "Wasted" app:

1. Check the box saying "Wipe Data" (you can optionally check wipe eSim if yiu also want that to happen)

2. Tap the bottom button saying [Off] which would ask you to give permission to the app as a Device Administrator, giving it the power to wipe your device.

3. Tap the gear button on top right

4. Scroll down to the "Lock" and check that

5. Tap the upper left button with the 3 horizontal lines

6. Tap the "Lock" menu option

7. Enter a value. I personally would use something like 24 or 48 hours. Note that 24H automatically becomes 1D in the app, idk why but thats just some weird quirks with the app.

For the Duress app, it doesn't really work anymore on the phone I'm using, so you might have to do your own testing.

Edit: Make sure you dont get drunk and passed out for 24 hours because then your phone gets wiped lol. Good luck, I didn't make the app so be careful with it, don't blame me if your accidentally get your device wiped when you didnt want it to.

Edit 2: Also you cant really know if these apps works on your particular phone unless you test it yourself, that means wiping it. So you might wanna back up your phone then trigger the wipe to see if it works. Dont wanna get caught at a protest only to find out the app failed.
