CallerSmart Reverse Lookup Phone Book + Caller ID

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!



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 go beyond our free search results and immediately tap into our exclusive paid data sources or see who has previously searched a number:

- 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 phone numbers which are important to you. You will get notified about new searches, comments, and phone book updates for those numbers. 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:

- CallerSmart Premium: $3.99 per month

You can monitor up to 5 phone numbers at once with a subscription to our CallerSmart Premium service.

If you choose to subscribe, payment will be handled via your iTunes account inside our app. Furthermore, your subscription will automatically renew each month and will be charged to your credit card on file with iTunes.

If you would like to cancel, you must do so at least 24 hours prior to the end of your current subscription via iTunes. Otherwise, your subscription will automatically renew. You can turn off auto-renew at any time via your iTunes account settings, which can be easily reached via the Manage Subscription section of our app.

CallerSmart Reverse Lookup Phone Book + Caller ID Reviews


It's really FREE  late-lori  4 star

This app is great and best of all it is free. It's not like other apps that trick you to think its free, this one really works. It does not give you info on every single number, but it does for most of them.

Good first step!  Spike H.G.  4 star

I use this often as a good first step to check unfamiliar calls missed. Doesn't always complete the picture for me but always worth a shot. I leave my feedback so as to help others and make the app better in my own small way :-) Haven't tried to paid services offered yet.

Good tracking app  ENTERTAININGLY nice  4 star

This is by far the best phone number tracking app that I've come across!!! I only wish other sites had this kind of information for free!!! The only thing missing, I think, is free reports of phone numbers. Then it would be absolutely PERFECT!!!


So far so good  Autoblast  5 star

Call Smart Updates  Living the life of a blogger  1 star

According to updates this app is unable to update due to incompatible. I have an iPhone 5s and am very upset about it not updating at all, it is a very useful tool, please fix whatever it is so we can continue to use.

Major Hassle

Once was useful and almost fun  Major Hassle  1 star

It won't even open now. Bad update? I don't know. I was climbing the ranks and using this app but now it will not open. I deleted it and reinstalled it, but still won't open. It's now gone.


Waste of space  Mzsweet0424  3 star

Ever since I've downloaded this app, I've had numerous numbers that I don't know call me and it's very annoying. Thinking about uninstalling.


Reporting spam  Pwhitty1  5 star

I get 5-10 spam calls a day and this app is a helpful tool in finding out who they are.


Bogus app  Deanspeer  1 star

Will take you google and login information for Facebook but will not open. Probably a info theft app. Do not use.


Not that good  mray51254  1 star

You have to pay for it

Callersmart  Apez78  5 star

Pretty cool reverse phone lookup. It also has a spam call blocker for your phone, I haven't used it yet but if it works that'd be great.

Dinky Moi

Why I like this App  Dinky Moi  5 star

I have received a lot of calls lately from few people Who I don't know. It's awesome being able to find out who they are.


Basically does nothing  BambiRaptorrr  3 star

You have to enter the numbers, it doesn't track any incoming numbers and does nothing for blocked/hidden numbers or people using their iphone from an icloud account to Facetime you. Basically it did nothing for me.


Awesome  BearLinc  5 star

Best App ever for looking up numbers.


Review  Wit7689  5 star
