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 4 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, etc. - all 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.

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



CallerSmart is free to download and use. We offer two paid services to help fund our app development, both of which are optional:

First, our Premium Report Credits let you either go beyond our free search results and immediately tap into our own exclusive private data sources, or see who has previously searched a number. Pricing for these Credits is as follows:

- Premium Report Credit: $3.99
- Pack of 2 Premium Report Credits: $4.99
- Pack of 3 Premium Report Credits: $5.99

Second, our CallerSmart Premium service is subscription-based. It lets you see who has previously been snooping on your phone number. You will get notified about new searches, comments, and phone book updates for your number. In addition, CallerSmart Premium comes with twice as much automatic spam call blocking, and the ability to hide your own reverse lookups from other users. Pricing is as follows:

- CallerSmart Premium: $3.99 per month

If you choose to subscribe to our CallerSmart Premium service, a $3.99 monthly purchase will be applied to your iTunes account. Payment will be handled via your iTunes account inside our app. Your account's subscription will be charged for renewal within 24 hours prior to the end of the current period automatically at a cost of $3.99 per month.

If you would like to cancel, you must turn off auto-renew at least 24 hours prior to the end of your current subscription via iTunes. You can turn off auto-renew at anytime via your iPhone’s account settings by following these instructions from Apple: For more information, see and

This app is AMAZING!!

So I was skeptical at first because I’ve tried a million other apps that are supposed to work and provide all this information and they either don’t work or want you to pay a bunch of money…..NOT THIS APP!! This app really works!! Type in a phone number and you can literally use this app to find out ANYTHING on whoever’s number it is. Yes you have to pay for tokens which is like $3.99 but you get the name on the phone, their address, job, criminal history, if their married, who their related to, their email, and much more ! Totally worth it ! It really works! And if you think your spouse is cheating….well this app will tell you everything you need to know !! MUST HAVE APP!!!!! I’d give it 10 stars if I could !!!

I've been getting multiple spam calls a day lately so I've upgraded to premium. Premium must mean nothing because nothing changed. Searches still don't bring better results, spam calls are still not blocked, this app does nothing my phone's own blocker and a plain Google search can't do. What's the point of having it? I'm so frustrated I even paid that small amount just to have no adds maybe? Not worth it!

Developer Response ,

Hi Mamazsu, We're sorry to hear that CallerSmart Premium wasn't what you expected it to be. It's important to note that the Premium subscription comes with Premium Number Monitoring, which is different from our Premium Lookup Reports. Additionally, our automatic spam call blocker unfortunately can't block all spam calls, only those from numbers who have been reported to the FTC and in our phone book. You can reach us at if you'd like to let us know about any other issues you had. Thanks, Your CallerSmart Team

Not super helpful

I get at least 2 spam calls a day, sometimes more. The same scam (same recording) uses different phone numbers for every call. I got this app hoping it would help; I tried manually searching the numbers and marking them all as spam. 3rd number they called me with today came up as “this is not a phone number” in this app’s search function. Yes, it is a number, they were using it to bother me today. And so I gave up on marking the endless numbers as spam for other users.

Then today I got a wonderful 4th call for the day, and this app made no difference whatsoever. I activated the “filter out spam” feature of theirs through my settings, but spammers still called me just the same. What is even the point to this app, if it can’t find numbers being used to call you and doesn’t block phony calls?
