The best call blocker apps automatically stop robocalls and, at the same time, allow users to customize call blocking rules. They feature a reverse phone lookup tool with important contact details, including the caller’s name and location. In addition, they have built-in call screening tools, which display who’s on the other end of the line—helping users decide whether to accept, decline, or send the call to voicemail.
Not all call blocking apps are equal. Some have valuable add-on features, such as voice-over-internet-protocol (VoIP) call routing tools and spam text blocking. If you’re looking for the best call blocker app for your business, consider the following providers according to your unique needs:
- YouMail: Best overall for call blocking and handling

YouMail ranks first in our list of call block apps, offering powerful call rejection tools complemented by call handling features. It automatically recognizes robocalls and phone scams, keeps the phone from ringing, and plays a prerecorded “out of service” message for the caller. This effectively prevents businesses from wasting precious time on unnecessary calls and falling victim to fraudulent activities.
On top of this, our best call blocking app features a reverse lookup tool that provides the caller’s important details, allowing you to know who exactly is on the other end of the line. If a phone number is suspicious, easily add it to your blocklist and receive no further calls from the number.
Aside from robust call blocking, YouMail provides VoIP business phone features, such as virtual assistant, simultaneous and sequential call forwarding, voicemail, and custom greetings. With this, your customer service team is able to manage multiple calls more efficiently.
While the provider is an excellent platform, it’s not equipped to block spam messages, a complementary capability to call blocking that other providers offer. RoboKiller, for instance, has the technology to analyze the metadata of text messages and evaluate if it’s spam.
YouMail Features

- Call screening: Block unwanted callers while letting verified callers through. Unrecognized callers must pass an audio captcha test to reach your business and ring your phone.
- Virtual phone number: All YouMail plans have a free second phone number. Get up to 15 business phone numbers to provide more communication channels for customers.
- Autoreplies: The platform automatically sends a text to callers you missed. Configure your message, directing customers to a link to your calendar to make appointments or to your website for more information about products and services.
Hiya: Best for Personalized Call Protection
What We Liked
- Offers a free version and an affordable subscription
- Allows integrations through application programming interface (API) and software development kit (SDK)
- Analytics measure the impact of call branding
Where It Falls Behind
- Doesn’t block text messages from the blocked numbers
- Lacks VoIP tools, like call routing
- Limited branded call feature in some carriers
Hiya Pricing
- Free: Call nuisance and fraud detection alerts, block list, caller ID, and unlimited number lookups (for numbers belonging to businesses only, not individuals)
- Monthly/Yearly: $2.99/$14.99 for automatic call blocking, frequent spam updates, premium number lookups, premium caller ID, and neighborhood filter (blocking specific area codes)
- Free trial: 7 days
Hiya is the top call blocker app for personalized call filtering, analyzing a user’s past interactions with different phone numbers to determine if a call is wanted or unwanted. The platform recognizes a legitimate call when a user frequently accepts calls from a specific caller. It deems a call unwanted when made at an unusual time and from a local number with no prior interactions.
The platform is likewise able to distinguish calls that could be wanted or unwanted for different users. A call from an insurance provider is vital if the user is waiting for an update on a claim they submitted. However, Hiya considers a call from the same organization unwanted and spammy if the user isn’t a client of the insurance company.
While Hiya is a great tool for call filtering, one disadvantage of using the phone call block app is its limit on the number of premium business and personal name lookups (200 per month). In contrast, YouMail doesn’t put a cap on the number of reverse lookups. You won’t incur additional charges if you need to identify several phone numbers.
Hiya Features

- Fraud detection: The call blocker platform takes into account various metrics related to reputation, behavior, and persona to spot spam calls. The factors considered include user reports, call flow, time of day, and call spoofing detection.
- Enterprise caller scoring: This feature looks at the caller’s calling history, including all the numbers they own, to eliminate the risk of connecting with spam callers practicing number rotation. Number rotation refers to switching numbers to prevent being identified as spam.
- Branded call: Show your company name and location when calling customers to increase brand awareness. Include your organization’s logo for better brand recognition.
RoboKiller: Best for Machine Learning-powered Call Blocking
What We Liked
- Features customizable call blocking
- Blocks spam texts

- Free trial: 7 days
*The paid plans include spam call blocking, real-time call screening, block and allow lists, visual voicemail, and live audio fingerprinting.
RoboKiller is the best call blocking app for businesses wanting to use artificial intelligence (AI) to stop unwanted calls. Its predictive and proactive call blocking technology examines the metadata behind a call to automatically filter out spam. The patented audio fingerprinting technology captures a recording and compares this with other similar fingerprints recorded in its global database, thereby offering an accurate confirmation of whether a call is spam or not.
The best part about RoboKiller is its Answer Bots, which are funny and clever prerecorded audio clips that automatically play when the platform detects a spam call. It makes scammers think they’re talking to an actual human being. It wastes bad actors’ time, keeping them from deceiving more people.
The downside of choosing RoboKiller is that it doesn’t have a free version. To access its features, you must pay for the subscription, which costs $4.99 monthly. Other call blocker apps, like YouMail and Hiya, have free plans that feature spam call detection and reverse phone lookup.
RoboKiller Features

These pieces of information are presented in visually appealing graphics, so it’s easier to read and understand them.

Upgrade to its paid subscription plans, Premium or Business, to unlock other valuable features. Unfortunately, the Business packages come with expensive rates, as they are calculated based on the listed phone numbers. For five numbers, you’ll pay $750 quarterly.
Small teams that are only starting will benefit from more affordable options, like Hiya and RoboKiller, which start at $2.99 and $4.99 a month, respectively.
Truecaller Features

TrapCall: Best for Number Unmasking
What We Liked

- Enables call recording
- Regular updates on the global spam list
Where It Falls Behind
- Lacks transparency in pricing

TrapCall Pricing
TrapCall doesn’t publish its subscription rates.
- Free trial: 7 days
TrapCall is the best phone blocker for dealing with blocked, private, restricted, and no caller IDs, as it unmasks phone numbers. When a call with a hidden caller ID comes through your phone, reject or decline the call and wait for TrapCall’s analysis. After a few seconds, your phone will ring again with the caller’s phone number displayed. If you don’t recognize the number, run it through TrapCall’s reverse number lookup tool to determine who’s on the other end of the line.
If you decide to block a phone number, callers will hear a prerecorded message about your number no longer in service. This effectively keeps them from contacting you again. With TrapCall’s simple, easy-to-use interface, it’s one of the best call blockers for Android and iOS.
However, note that if you choose this platform, you must reach out to the provider for its subscription rates since it doesn’t publish its pricing. Other call barring apps are more transparent with their fees. YouMail has the most comprehensive pricing information, making it easier for businesses to know important inclusions for each subscription plan.
TrapCall Features
TrapCall lets you add contact numbers to a blocklist. (Source: Apple Store)
- Custom blocklist: Once you add callers to your blocklist, every time they call, TrapCall plays a message saying, “The number you’ve dialed has been disconnected or is no longer in service.”
- Privacy lock: TrapCall will ask unknown callers to identify themselves by stating their names. If you answer, you’ll hear their recorded name and have the option to accept, hang up, or send the call to voicemail.
- Neighbor spoofing detection: The system automatically recognizes neighbor spoofing or malicious activity that involves scammers using local phone numbers with an area code and prefix similar to yours.
