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

Monitor up to 5 phone numbers at once with a subscription to our CallerSmart Premium service. A $3.99 monthly purchase will be applied to your iTunes account if you choose to subscribe. Payment will be handled via your iTunes account inside our app. Furthermore, your subscription will automatically renew each month for $3.99 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 via your iTunes account settings. For more information, see http://www.callersmart.com/terms and http://www.callersmart.com/privacy.

Seems fine; a bit gimmicky

What I seek is an app that will direct me to whom ever owns the robo call numbers I keep getting, so I know how to report them properly to authorities. This one is helpful but it seems like it will not do much for me unless I opt for a paid subscription. That's fine, and I hope they do well in their sales. Scam calls are not identified or marked as unknown. At least one repeat caller is marked in app as an invalid number. It has a point system that rewards reviews/feedback which some may love, but are just a cute distraction to me. My goal in the end, is to find a way to shut down scam callers permanently.

Hi Closer918, Thanks for your honest feedback, we appreciate you rating us here in the App Store! Have you tried turning on our Automatic Spam Call Blocking feature? It may help eliminate many of those annoying robocalls you receive. If you'd like more information or want to share anymore feedback with us, you can reach us at feedback@callersmart.com. Thanks, Your CallerSmart Team

Definitely not worth the money

After paying I still don’t have any true caller id. And yes I have the app configured to allow calls. Pretty much all I am paying for is to look up numbers that call me manually. Not what I need. I tried another app and at least it would show who was calling even when the screen is locked. As far as I can tell all the $3.99 a month does is block ads. Even a number that I know is suspected spam it’s not even listed, this number has called several times in the last year. I looked up this number online and it’s been listed as a severe high risk. I am definitely not paying even more money to get a “premium search” for that number or any other ones.

Hi Forever_shadow, We're sorry to hear you had this experience. CallerSmart Premium doesn't currently cover unlimited Premium Lookups, but it does allow for ad-free and anonymous lookups. As well as enhanced spam call blocking and the ability to monitor the activity on any five phone numbers. You can get in touch with us at feedback@callersmart.com if you'd like more information on CallerSmart Premium or instructions on how to receive a refund. Thanks, Your CallerSmart Team

Oh yeah oh yeah oh yeah ,


This app does nothing. You as the app user do all the work. This app only shows you how to block numbers from your phone.
After communicating this frustration with customer support they told me this app doesn’t actually stop spam calls. I didn’t receive a crazy amount of spam calls before downloading the app and I received zero spam texts. So I figured there was no need to keep an app that isn’t doing anything for me. So I deleted the app.
What’s crazy now is that I am receiving at least 25 spam calls a day and about 10 spam texts a day. Seems suspicious, no? I haven’t been able to prove this app has something to do with this madness yet, but I will.
For your sanity, DO NOT USE THIS APP!!!

Hi Oh yeah oh yeah oh yeah, We're sorry to hear you didn't find our app helpful. We do have an automatic spam call blocking feature, but the user does need to turn it on in their iPhone's settings and it doesn't block every spam call. We base the numbers we block off of FCC complaint reports and also our users' feedback. Due to caller ID spoofing and the amount of U.S. phone numbers it's impossible for us to block all spam calls. Regarding an increase in calls and texts after downloading our app, we don't share any user information with third parties. Thanks, Your CallerSmart Team
