Description

Firewall is the only app that can handle the state of spam calls today.

BLOCK 100% OF SPAM CALLS
Most robocall blocker apps try to determine which numbers spammers use, but spam callers and robocallers switch numbers and use fake Caller IDs to get around those blockers. Firewall works the opposite way. You create a list of people from your contacts who you want to hear from, and only those approved callers can ring through. All other callers get blocked or sent to voicemail.

PROTECT YOUR PRIVACY AND PRODUCTIVITY
Firewall is guaranteed to block spam calls, fraud calls, and robocalls, but it does a lot more to help keep your number private and keep you productive:

- Avoid unwanted text messages, with our SMS spam blocker

- Eliminate disruptions from legal but annoying calls (car dealers, salespeople, etc)

- Screen messages with visual voicemail

- Pause the blocker when expecting an important call from an unknown number

- Protect your personal number by making anonymous outbound calls to unknown numbers

- Keep your privacy intact - your contacts are stored locally unlike other robocall blocker apps

- Get support from our U.S. based customer service team 7 days a week

Some of our favorite features include:

BEST-IN-CLASS VISUAL VOICEMAIL
Quickly see who called and what they wanted, so you can determine if you want to call them back, block them, or add them to your allowed contacts list.

OPTIONAL SMS FILTER
SMS spam is on the rise. Flip on Firewall’s SMS filter to keep scammers and marketers from polluting your messages with unwanted texts.

PRIVACY FOR ALL
Firewall is built by Ad Hoc Labs, the same company that makes Burner, the award-winning 2nd phone number app. We build privacy-first communications tools, and unlike many other companies, we value privacy above all else. We would never sell your data or compromise your privacy.
