Call Hole

UNWANTED CALLS GO IN

Keep a list of numbers and patterns, and Call Hole rejects or silences the calls that match. It works on your phone alone: no server, no account, no ads.

Get it on Google Play

Free for Android 10 and newer.

Call Hole's home screen: blocking is on, with the number of calls blocked and screened today.

Your rules, your phone

Block one number, or every number that starts with a prefix, ends with some digits or fits a pattern. Always allow the ones that matter. Call Hole reads numbers the way your country writes them, with or without the country code.

It uses Android's own call screening, so your phone app stays the same, and calls from your contacts always ring.

  • Exact numbers, starts with, ends with, contains, wildcards and regular expressions.
  • Block hidden numbers, international calls and calls that fail the carrier's caller ID check.
  • Quiet hours: only contacts and allowed numbers ring at night.
  • Groups of rules you can switch off together or limit to certain days and hours.
  • Reject a call or just silence it, per rule.
  • An activity log with one-tap block or allow, and statistics.
  • A Quick Settings tile and a home screen widget to pause blocking.
  • Export and import your rules as a file.

A look inside

  • The Rules screen with three blocked numbers, each with a switch and how often it matched.
    Block or allow any number or pattern
  • The Activity screen listing screened calls, some rejected and some allowed, each with the reason.
    See every call it checked, and why
  • The Statistics screen: 4 calls blocked and 2 that rang, with a chart of calls per day.
    Statistics for the last 7, 30 or 90 days

Private by design

Call Hole has no permission to use the internet, so nothing it knows can leave your phone. It never reads your contacts, your call history or your messages. The privacy policy has the details.

It is made by Nick, a software engineer, and published under the name GN33.
