Keeps visible calls from people outside your contacts from interrupting you while protection is active.

How it works

Known Calls Only is an Android app for people who want fewer interruptions from visible phone numbers they do not know. It works locally on your device and leaves your contacts and call history alone.

When protection is active, visible callers who are not saved in your contacts do not interrupt you. The app does not claim to handle hidden or private numbers, which Android may not make available for this purpose.
