App Description

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: https://support.apple.com/en-us/HT202039#iOS.
