This is a simple Android app that allows the user to:
- Block all calls by default.
- Allow people they know to call.
- Record (or select) a pre-recorded message to relay to would-be callers.
- Never allow unauthorized callers to leave a voicemail or otherwise disrupt your day. The phone won't even ring.
Use cases:
- Mitigate harassment attempts after a PII leak.
- Force people outside your inner circle to send you an email before calling.
