According to The New York Times, upwards of 48 billion Americans had been hounded by robocalls in 2018, a rise of 56.eight p.c over the earlier yr. That averages out to roughly 150 rip-off, telemarketing, and undesirable calls yearly for each grownup with a telephone—a quantity anticipated to balloon larger sooner or later.
That’s exactly why a cottage business prospers on the App Store, supplying instruments to fight this menace. Unfortunately, most name blocker options depend on outdated, ineffective blacklists, or worse but, require customers to do the heavy lifting by reporting rogue numbers as they pop up. A brand new app known as Firewall takes the alternative method: Whitelisting everybody you recognize and sending the remainder to limbo.
While which will sound like dropping a nuke in your yard to eliminate a number of pesky bugs, Firewall did a outstanding job of eliminating nuisance calls on my iPhone X. In current months I’ve acquired a handful of day by day intrusions, however after putting in Firewall, they had been totally eradicated.

Should a blocked caller turn into somebody you recognize utilizing a distinct quantity, they are often added to the whitelist in a pair faucets.
A couple of caveats
Remarkable as Firewall is snuffing out solicitors, there are a number of limitations value noting. For starters, the app at the moment solely works within the U.S. with AT&T, Sprint, T-Mobile, and Verizon. Intercepted calls are redirected to your iPhone utilizing VoIP, which consumes mobile or Wi-Fi knowledge relatively than plan minutes.
You can get round this by tapping the on-screen “switch to cell” choice, which reroutes the call-in progress to the mobile community. It’s slightly clunky however is useful whereas on unreliable wi-fi connections.
Also, you possibly can customise what’s spoken throughout voicemail greetings for whitelisted and blocked calls, however there’s no technique to document outgoing messages in your personal voice.
