If any app makes you feel bad, delete it and remove the stored credentials from your account. It worked really well for me.

Make your phone less useful. I don't have my work e-mail & Slack on my phone. So I can't even check my work calendar on it.

I used to have a few of the social networks apps and lots of utility apps that maybe I would use once a year. So I decided to delete them all.

Now, I only have some of the default Apple apps + WhatsApp, Telegram, Bank, Spotify, Lockwise, Scanner Pro, Google Authenticator, Google Map, and a few utility apps to manage cameras, smart LEDs, and my vacuum robot.
