About this app

Call Guardian is an advanced call blocking tool that protects your privacy and maintains your peace of mind. It automatically silences, rejects, or diverts unwanted calls, including spam, unknown numbers, or unauthorized contacts.

Set custom filters, allow only trusted contacts, and create an allow list to avoid blocking important calls like those from delivery drivers or family members.

It includes STIR/SHAKEN verification to identify legitimate calls and prevent spoofing. All processing happens on your device, without collecting or sending your data.

Enjoy statistics, optional notifications, a history of blocked calls, and a simple and effective interface. You can also support the project with small donations.

Ratings and reviews

I've tried numerous apps in an effort to stop robo calls and scammers. I'm getting a minimum of 20 calls a day. The scams are primarily coming out of India. They spoof local numbers which makes most call blocking apps useless. This is the only app I've tried that has blocked 99% of these calls. It has a simple user interface which is fine with me. You'll still need to use the stock phone app. Apparently this is not a well known app but I'm sure that will be changing soon.

The app doesn't have a hangup option. Thereby, the caller can't leave a voicemail message, all they hear is a click on their end, and there is no ring on my phone. The app's reject function is not a direct hangup. it sends straight to voicemail. App needs the hangup capability. The app has a nice layout and probably works well as designed.

Great app. Nice, simple and clutter-free UI. Straight to the point kind of app, no gimmicky. I love the fact that it blocks all numbers that aren't stored in my phone. -calls from new numbers etc. How I wish the dev would implement a way to use RegEx. -block calls based on a criteria the user set. That would be fantastic!
