What is an app that someone should most definitely NOT have on their phone?

One of the scam ones that pretends it's free then charges you $99 a week when the trial period is up.

Seriously , facebook .

The way it kills time and seduces people to stay longer ( because that's what they have been working on since day one ) is so destructive. Even with work or communication intentions, facebook is a fatal for your creativity and activity programs.

An app explaining local consent laws based on your phone’s location data.
