We put the "poof" in "spoofed calls".
STFU is a phone call blocker for Android Q and above.
Things STFU does NOT do:
- Caller ID
- Cloud sync
- Steal your contact list
- Make girls call you back
Things STFU does do:
- Block phone numbers by prefix
You can think of this as the phone call equivalent of NekoSMS, although this app is not nearly as polished.
If you live in the US, this app also comes with a database of all the area codes by state. You can use this to easily block all calls coming from an entire state (which is super useful if your number is from that state, but you no longer live there and keep getting spam calls with spoofed numbers).
- Android phone running Android Q (10) or newer
This app cannot block callers on your contact list. This is a limitation
of the API we use,
CallScreeningService.
An interesting consequence of this is that you can block all non-contacts
by making a filter rule that matches everything (i.e. +).
