Numbo: Call Blocker rids you of all surprise and spam callers. Sounds good, right? Never again will you have to wonder who‘s on the other end of the line – Call Blocker will take care of all your unwanted and unknown calls and messages. Simply enjoy your life without distractions.

Call Blocker is an amazing tool that will help you:

Call Blocker immediately tells you whether the person calling you is one of your contacts or possibly a blacklisted number from the database. The app offers you Caller ID lookup, showing your business information instead of only the usual location. You can choose which action to take and get rid of phone spammers forever!

Block all those unwanted numbers - robocalls, auto calls, telemarketers, and other scam callers. Be the one who decides which calls and messages are worth your attention.

The app shows you caller ID or blocks calls automatically based on your preferences. You can choose a different setting for each category for the database - so block spam, scam, and telemarketing calls but let the app identify trustworthy numbers or unknown callers.

From now on, you can filter your incoming text messages with keywords. The app will detect the entered keyword in your texts and filter it into a junk folder.

The app compares all your calls with the numbers in our database. The database is updated regularly to ensure your privacy and security. We deal with unwanted numbers so you don’t have to.

Add numbers of unwanted callers to a user-shared database. We’ve got your privacy covered and will never share any of your contacts with the list.

Decide what to do with unwanted callers. Do you want to block them from ever calling you? Or do you want to leave them access but be warned when their number comes up? Or do you want to deal with each number individually? It's all up to your decision.

You can also compare any missed calls from unknown numbers with the database list and find out the identity of the caller easily.

Back up your blacklist and access it easily by signing into your account and sharing it across all your devices.

Get access to a high-quality database of spam numbers that grows day by day and is verified by our professional team. After subscribing, you’ll also be able to see comments from other users that can help you decide whether to pick up or not.

All the data from the database with unwanted numbers and callers is provided by Tellows.
We offer a monthly or yearly subscription. The subscriptions are auto-renewable. Payment will be charged to your iTunes Account at confirmation of purchase. The subscription automatically renews unless auto-renew is turned off 24 hours before the end of the current period. All subscriptions can be managed by the user in Account Settings.

The call blocker I was looking for

I am very pleased with Numbo call blocker. It is an excellent app and you will be satisfied with Numbo that avoids you from spam numbers. I paid for a year and it seemed to have worked great. Call blocker works fine for months and everything seems to be alright. My experience is the finest and as they said: Numbo call blocker will take care of all your unwanted and unknown calls and messages. Simply enjoy your life without distractions. And do you know what? It is true, no bs.
Numbo has many useful features that you could really enjoy. I've felt in love with filtering and blocking messages via keyword setting. You could use it against spammers, robo callers, scum numbers, but also (like me) against your ex. Very cool app feature. The second feature that I really appreciate is reverse lookup. In every moment I can see who is calling me, you need it right? The top of the hill called Numbo call blocker is our own private blacklist and category filter, that works in a very good way.
For me and my friends, Numbo is the number one in antispam solution and I will use it till I can. My advice is to buy even month subscription and enjoy life without annoying spammers. Just give it the chance. I'm sure you worth this call blocker 👍

Awesome app

This is an excellent app it gets every unwanted call I receive. Does what it should. So, thank you! You wouldn't believe that I have about 50+ unsolicited numbers already on my list for “Blacklist”! Y'all are literally saving me from jumping thru my phone to strangle these annoying morons who call and bother me!!!!
I was looking for a solution of blocking some callers and this was recommended for my situation. I was being harassed by my ex, and he kept calling from a restricted number and different burner numbers.
The local law enforcement refuse to do anything about it. But with NUMBO I was finally able to block private and restricted calls along with unsaved numbers. THANK YOU to the developers of this app. This app gave me so much more peace of mind.
Than I realized other great features. Because it is very easy to manage and use all aspects of Numbo. This app really fulfilled all expectations by 100%. App can get rid of all surprise and spam callers for you. That sounds good, right? Never again will you have to wonder, or be worried about who's on the other end of the line. Numbo Call Blocker will take care of all your unwanted and unknown calls and messages. Now I can simply enjoy your life without distractions or stressful situations.
There was No-one bad issue. And this app is very light. Doesn't consume much power and never caused any kind of conflict with other apps.
Again, app is great, works great and I have zero complaints! 😁

Excellent app

I had recently been getting a lot of spam calls that I couldn’t tell were spam calls until I answered. Given the fact that I make and receive a lot of phone calls for work, these spam calls really got in the way of getting things done. I began looking for call blocking alternatives and found numbo. The interface is very easy to use and the caller identification is perfect! The free trial let me gauge whether or not I wanted to pay for the subscription, and the subscription is definitely worth it! You should definitely get this app if you are getting too many spam calls and want to know whether or not to answer.
