YouMail: Best Overall Call Blocker App
What We Like
- Free plan option for individual users
- Offers local and vanity numbers
- Automatic SMS (short messaging service) reply
What's Missing
- Lacks a desktop application
- Secondary plan eats into your primary number’s plan limits
- Limited customer service channels
YouMail Monthly Pricing*
- Free: Basic call and voicemail protection
- Plus: $7.99 for total spam protection
- Essentials: $14.99 for call screening and custom greetings
- Complete: $24.99 for five new phone numbers, auto-attendant, and call handling
- Ultimate: $34.99 for unlimited visual voicemail and 15 phone numbers
*Save 20% when you opt for yearly billing
YouMail is our pick for the best overall free apps to block spam calls—available for iOS and Android phones and landline desktop devices. YouMail stands out due to its added voice-over-internet-protocol (VoIP) business phone features, including voicemail transcription and virtual phone numbers (from one up to 15) per plan. Users also have access to call routing features with virtual receptionists.
Much like TrapCall, it delivers a “number out of service” message to spam callers and ends the call without forwarding it to your voicemail. However, YouMail can’t protect your text inbox from spam and scam messages. If you’re looking for such a feature, choose Call Control. This application filters spam messages into a separate folder.
YouMail Features

- Call screening: YouMail’s call screening is excellent for blocking unwanted callers while letting verified callers through. Unrecognized callers need to get through an audio captcha and press a couple of keys to get through and ring your phone.
- Free phone number: All YouMail plans have a free second phone number. Get up to 15 local or vanity business phone numbers with free and paid services.
- VoIP services: The free plan includes 120 voice minutes. Paid plans additionally offer call management features, such as an auto-attendant, automatic SMS replies for missed calls, and call routing to extensions.
RoboKiller: Best Spam Blocker App Offering Strong Scammer Responses
What We Like
- Spam text blocking
- Easy application set up for both iOS and Android
- Well-designed, easy-to-navigate interface
What's Missing
- Bots are sometimes unreliable
- Reduces calls, but some calls still get through
- Limited customer service availability
RoboKiller Pricing*
- Monthly Protection Plan: $4.99 per month
- Annual Protection: $39.99 per year
- Free trial: 7 days
*Save up to 33% with annual billing
RoboKiller is the best spam call blocker that gives individuals and businesses the power to fight against spam using answer bots. As your secret weapon against distractions and unwanted calls, RoboKiller uses prerecorded audio files that are played back to spam and robo-callers that waste scammers’ time instead of yours. Of all the best apps to block spam calls, this is one of the more entertaining and gratifying ways to strike back.
Unfortunately, RoboKiller is at the costlier end of the spectrum compared to other providers, which can become expensive in the long run. If you’re on a budget, Hiya offers a free app for blocking calls that’s also advertisement-free.
RoboKiller Features

- Audio fingerprinting: This RoboKiller feature takes a recording of each robo-caller’s unique audio recording and compares it to other “audio fingerprints” to identify phone scams effectively.
- Spam text blocking: With the increase of spam texts, RoboKiller uses a predictive spam call blocking algorithm that proactively analyzes each incoming call before it rings your phone and determines whether it’s spam.
- Radar: Opting for radar makes you part of a patrol network. This allows you to submit your spam reports daily, enhancing RoboKiller’s algorithm for blocking unwanted calls.
Hiya: Best for Companies Needing Multilanguage Solutions
What We Like
- Free version is also ad-free

Hiya offers a free call blocker application version with premium robocall blocking services without advertisements. In addition to its low cost, this spam blocker supports multilanguages that are not limited to English, French, and Spanish. This is great for businesses with international numbers and a global presence. In addition to the cost-free version, if you’re interested in upgrading, try out its free trial for paid plans.
Unfortunately, one of the comments regarding Hiya is that while it’s intuitive, it can be a bit laggy or slow. For a more reliable service, check out YouMail, our top pick. In addition to offering a free version, upgrade your package to VoIP features that include inclusive minutes and voicemail.
Hiya Features

- Caller ID management: Hiya lets you register and correct your business information in the Hiya database. The tool also enables you to report inaccurate or offensive comments listed under your phone number.

This free phone-blocking app allows you to select which phone numbers will be on your blacklist and choose whether you’re blocking messages, calls, or both. Its Urgent Messages feature lets you respond with animated emojis and send quick note messages. However, its iOS application is found to be inferior to the Android version.
Truecaller has gotten feedback that its ads can be irritating. If you’re looking for an ad-free call block app, check out Hiya. Its free version is advertisement-free, and like the other providers on this list, Hiya blocks spam and scam calls and displays caller ID names and reasons for incoming calls.
Truecaller Features

- Caller ID: Truecaller’s Caller ID allows you to identify any domestic or international number by automatically detecting the location and name of the person calling. There are different True Colors to identify callers; blue is for a standard call, red is for scammers, purple is for priority calls, and green indicates a verified business.
- Spam blocking: The application blocks telemarketers, scams, frauds, and robocalls based on real-time community reports. Community members report numbers in real time, so everyone is always protected against unwanted calls.
- Smart SMS: Truecaller is able to manage all your messaging through a single application. Make it your main SMS app to identify spam, schedule messages, use chat, and track upcoming bills. This feature, however, is only available in select countries.

TrapCall lands in the top spot when it comes to unmasking calls. It lets you regain your privacy by letting you know who’s hiding behind those pesky “No Caller ID” and “Restricted” calls. It boasts of a patented technology that identifies your callers. All you have to do is decline the call and calls ring back to you unmasked in a matter of seconds. Unfortunately, you must first decline the call for the app to ID the caller.
At this time, TrapCall is only available in the United States; if you’re looking for the best call-blocking apps that offer more global coverage, try Hiya. This call blocker supports multiple languages, including English, French, and German.
TrapCall Features

- 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.”
- Record incoming calls: If blocking callers doesn’t work, capture incoming calls for documentation with this recording feature. This is particularly useful if you need proof of harassment or want to unmask someone calling you.

Call Control is one of the most widely used platforms for blocking spam, robocalls, and telemarketers. Call Control is available for desktop landlines, Android, and iOS, and protects your landline using the companion smartphone app. In addition to supporting both mobile and landline devices, it also comes with a built-in feature called CommunityIQ, which facilitates creating Do Not Call reports and community reports.
While the app automatically blocks the calls from those on the personal blacklist and spam callers, if you want to know who is calling, try TrapCall. It works by stripping away hidden phone number information that prevents you from identifying the caller. Use this app to block calls and know who is on the other end of each incoming call.

Frequently Asked Questions (FAQs)
Can you block a call without the caller knowing?
Typically, no notification is sent to the caller when they are blocked. Instead, they might hear a busy signal or a message stating that the call couldn’t go through. Some providers also present blocked callers with a busy signal. Other providers might allow the caller to hear a single ring before immediately diverting the call to voicemail.
Will a call blocker app block unwanted texts?
Not every call blocker app will stop text messages. For this type of functionality, consider a blocker with SMS blocking. There are also dedicated text message-blocking apps on the market.
Can you see if a blocked number has tried to contact you?
Most providers, like Hiya and Trapcall, alert you when a blocked number has tried to contact you. Additionally, some providers will create call histories for your blocked numbers in their block lists so that you have a detailed record of blocked called attempts.
Bottom Line
Using a paid or free call blocker app gives you extra protection against scammers and minimizes distractions and unwanted phone interruptions. With all the available applications, you will want an intelligent application that features effective caller identification and an intuitive interface.
