CallerSmart helps you investigate mystery phone numbers, and avoid unwanted calls and texts.

Huffington Post, Mashable, Inc. and many others have featured us, and BuzzFeed nicknamed our app “turnt up caller ID” in their “11 Things To Do Before You Start Dating Online” article.

iPhone users have made CallerSmart the #1 reverse phone lookup utility app in the App Store - for over 2 years!

Why? Because we've made a game out of keeping the U.S. phone book up-to-date for all. That's why you can also get free prizes and unlock fun Smart Badges, just for helping keep our listings accurate for everyone.


- Find out the full name and location behind a mystery number that's shown up on your caller ID.

- Investigate a suspicious text you've gotten, including useful comments from other users.

- Avoid annoying bill collectors, telemarketers, scammers, prank callers, and ex-lovers, so you don't mistakenly call someone back you don't want to talk to.

- Monitor your phone number to see who has been looking for you, including past searches.

- Protect your children, your partner, or your business from others secretly snooping on phone numbers that are important to you.

- Non-invasive: Access to your contacts is optional, and you can easily opt your number out of our community phone book.

Join hundreds of thousands of satisfied CallerSmart users and discover the best caller ID solution for your iPhone!

Customer Reviews

Needs Lotta Work but Badges are GREAT!

Try it for yourself! Badges are fun. Usually The Numbers I've looked up are not in the system yet. I do however, like the badges' very entertaining info. You learn many interesting new things about famous people in the making of our history as you progress through each badge level. A couple of people I thought I knew everything about - Thomas Jefferson and Harriet Tubman. When I achieved the badge for each of them. Jefferson wasn't only a slave owner and US president, he was extremely creative and a future thinker. He is the one that had the forethought for the necessary division of church and state. He realized the crossing of state and church swords can't ever happen. Jefferson KNEW the division and separateness was of dire importance and an extremely vital necessity that it be written into our Declaration/Constitution/ Bill of Rights triple threat. Unfortunately, he only planned for free white males at the time. Women and those of color or other nationalities were pretty much fracked over. That's why his documents needed a lot of polishing up to resemble what we know today. There was also much more to the story I thought I knew of tough Harriet Tubman and The Underground Railroad (Hint: Her Given Name Wasn't Really Harriet Tubman)

Fun App motivates you to update

The main drawback of this app is that many of the phone numbers I've searched are not yet added to its database. However, you get points that leads to tons of badges making it fun. If my search on the app yields no results, then I always search various websites to see if others have reported the phone number. I add my results via feedback on this app as well as add number to it's database. So this app will get stronger as we continue to update it. Users can also rate your feedback to give you points and you get points for adding the phone number. Once I've researched the number, I block it on my cellphone.

Quick and Easy

I've only used this app a couple of times so I can only give a limited review. So far the app has done what it says. I am trying not to use up all my points so I don't put in a lot of numbers but I also don't receive that many unknown calls. I hated having to go to the websites that lure you in for free reverse lookup and then before giving the name gotcha put your cc info. At least this app gives you the information.
