TikTok (App) 

Even though it's considered an App it does not deserve this status because Apps serve purposes.
It's a social media platform where people who don't question their life choices share videos everyone else would be ashamed of but they become pseudo-famous with.

Friend: I just downloaded TikTok (App)
Me: I just blocked you irl

fuck you in the app 

An expression of derisive anger and frustration when a business coercively informs you that you really should get their app in order to do business with them.

Sir, I am not at all interested in amassing endless apps on my phone, now or in the future, so fuck you in the app!

just contact me through the app 

What a woman tells a man that she met on Tinder when he asks for her number and/or a second date and she does not want to see him again.

You: I had a great time, it would be great to hangout again
Her: Me too
You: How can I get in touch with you?
Her: Just contact me through the app

Spider Web App 

The iPhone app that makes your phone appear, in all senses, to have a giant network of cracks and dents all over the screen. Usually occurs after multiple drops or one unfortunate fall down the stairs.

"Dude, what the hell happened to your iPhone?"
"I got the spider web app, man. Tight as hell, right?"
