# Fake Call App

An open-source call simulation app to escape awkward situations or play pranks.
8+
9+
Not only I couldn't find an open-source fake caller on the F-Droid or Google Play stores, I couldn't
10+
even find one that looked reasonably modern and not too obvious, worked with the screen off and wasn't run by an obvious ad farm,
11+
so I decided to vibe code my own. This app will never have any ads or collect any data, forever.
12+
13+
Tested on Google Pixel 9 Pro XL. Contributions are welcome.
