I'm having trouble concentrating or getting started on bigger projects for the school. So I wanted to ask if there's an app that locks certain websites and apps on my laptop and can only be unlocked again with a passowrt? I wanted to give this password to a friend or a friend and they only open the things when I'm done with my work
How about putting in the stupid cell phone?
Just leave a good friend you trust, change the password on your phone, and only tell it when you've prepared yourself enough. You do not need an app for that.
Be your own administrator! You need three user accounts: one admin, one to work and one for the rest.
As an administrator, you set the rights for the applications - one may do everything, the other only work.
Then you have to change at least the user.
To put friends in something, I find unfair.
