You may want to share a single device among multiple people, as a parent with children, or a teacher sharing a limited number of devices among their students. To do this, you switch between user accounts.
Klikaklu makes this easy. You can switch back and forth between accounts from a couple of places. The most direct is to tap on the user area of the home screen to view your profile. A button at the bottom, Change User, will prompt you to sign in a different user (or sign up a new one). After you’ve done this, the previous user will appear as an option below the Change User for quick switching back and forth between users. Klikaklu will optionally track each account’s password as well, so it can be as simple as tapping the button to switch user accounts.
For convenience, tapping Play (you’ll find it on the ‘hamburger’ menu in the upper right at this point) from the Hunt Overview screen on a hunt you’ve already completed will prompt you to switch to a different user as well. It will also include recently seen users.
