About this app

Callro screens calls from numbers that aren't in your contacts and silences or blocks likely spam before your phone rings, without ever asking for access to your contacts. Built to help protect seniors and their families from phone scams.

Callro's Gauntlet Engine is a multi-layer screening pipeline. The decision to allow, silence, or block a call is made on your phone, with no network call required. Your contacts and call audio never leave your device.

━━━ WHAT MAKES CALLRO DIFFERENT ━━━
- No contacts access — Callro never requests permission to read your address book
- Screening decisions are made on your phone, with no network call required
- No audio recording — Callro uses call details, never call audio
- No ads in the app
- Uses Android's call screening role, which you approve once in a system prompt

━━━ HOW IT WORKS ━━━
1. A call arrives from a number that isn't in your contacts
2. Callro screens it before your phone rings
3. The Gauntlet Engine runs its checks in real time
4. Likely spam is silenced or blocked. Calls that pass screening ring normally.
No call blocker is perfect. You can review every screened call in the Shield Log and allowlist a number with one tap.

━━━ WHO IT'S BUILT FOR ━━━
- Seniors tired of Medicare, IRS, and Social Security scam calls
- Adult children protecting elderly parents from phone scammers
- Anyone getting robocalls, warranty scam calls, or neighbor-spoofed numbers
- Privacy-conscious users who won't hand their contacts to an app

━━━ A DIFFERENT APPROACH TO PRIVACY ━━━
Many caller-ID apps ask for access to your contacts and look up incoming numbers on remote servers. Callro doesn't need your contacts, and it makes every screening decision on your phone. Its built-in reference data draws on U.S. government sources, including FTC complaint data, FCC robocall mitigation data, and NANPA numbering-plan data. No contact harvesting.

━━━ KEY FEATURES ━━━
- Multi-layer Gauntlet Engine call screening
- Silent rejection — identified spam is rejected before your phone rings
- Neighbor Spoof Detection — flags calls that mimic your own area code and exchange
- Built-in FTC, FCC, and NANPA reference data
- Fortress Mode — silences calls from every number that isn't on your allowlist, a number you've called before, or a recognized local medical facility with verified caller ID. Emergency calls are never affected
- Expecting a Call — temporarily let an unrecognized number through for one hour, with one tap
- Custom area code blocking
- Shield Log — your full call-screening history, kept on your phone
- One-tap allowlist for numbers you always want to receive
- Works automatically once it's set up

━━━ CALLS CALLRO IS DESIGNED TO HELP WITH ━━━
Medicare, IRS, Social Security, Amazon and warranty scam calls · robocalls · spoofed numbers · telemarketing calls · political robocalls. Callro scores calls on number reputation, caller-ID and spoofing signals, and calling patterns, not on anything the caller says.

━━━ PRICING ━━━
$9.99/month after a 7-day free trial. No credit card required to start. Cancel anytime in Google Play.

━━━ PRIVACY ━━━
Your contacts and call audio never leave your phone, and Callro never requests contacts permission. A limited set of data is collected, including masked records of blocked or silenced calls (last four digits, time, and action), app analytics, crash reports, and advertising attribution.

Ratings and reviews

Kudos to this app.. It's the best thing since the phone!! I was getting 2,000 or calls a calls day from telemarketers. after installing Callgro now I only get like 5. oh it's so peaceful.. the salesmen and agents are awesome, they call and make sure your happy with it during your free week trial period.. yes they let you try it for a week to make sure you can handle life without all of the telemarketers and unwanted calls.. I would recommend this to everyone!!!!!!¡!

I was getting overwhelmed by calls all day long and weekends too! Since I have subscribed to callro,I've only gotten calls from people that are on my call list as well as area codes that I choose. It's night and day difference as far as stress from solicitors and scammers... Your phone only rings for calls that you choose.. Thanks Callro!!! And keep up the good work...Get it people your missing out....

This is the best experience I have ever had from a single call blocking app. I highly recommend this app if you are experiencing a high volume of spam calls, they got rid of all the headache of the constant repeat calls and they are very understanding and helpful when it comes to the setting up process. Just a wonderful experience all together thanks again for everything.
