Most (if not all) cellular phone carriers do not offer the full caller ID service that exists for landline phones. When someone calls a mobile phone, the cell phone caller ID leaves out the name, only showing the phone number and/or city of the caller. Real caller ID shows the number & name of the caller. Since 2013, Greenflight has offered this invaluable free & real caller ID utility for the iOS architecture.

This tool may only be used to research phone numbers that called you or contacted you via social media. All use must comply with applicable international, federal, and local laws. The Caller-ID service is not a consumer reporting agency as by the Fair Credit Reporting Act.

Payment will be charged to your Apple ID account at the confirmation of purchase, or end of trial period, if applicable. Subscription automatically renews unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions by going to your account settings on the App Store after purchase.Any unused portion of a free trial period, if offered, will be forfeited when the user purchases a subscription to that publication, where applicable.

Seems to work on most instances.

It would be nice if when you did a reverse look up on a cell phone given even business often do have a land line, but may also have cell phones connected to the same company. As it’s frustrating when a private cell calls, no voicemail, n only lists a ruff geolocation over sizable area covered by the cell towers the call was sent from, however, as much as I’d like a name even if first intial, n last name or name of a particular business that’s connected to the billing statement for that particular cell number, not aware of privacy laws would allow the release of such info. As I get a lot of spam calls for some reason, so few years ago, stopped answering, any number not included on my contacts, as I figure if someone’s reaching out for ant legitimate reason then they will-leave a vm, with name, number they can reached at & the nature/purpose of the call. If they call n don’t leave a message, I figure I’m not likely missing out on anything other than a telemarketer soliciting me for one reason or another, n prefer to not have my personal or professional life interrupted by a solicitation, and stick by if no message it’s of no importance to me & I’d rather give my full time& attention to the person(s) presently I’m front of me than to be rude to the person in-front of me just to listen to an elevator speech.

Does exactly what it says it will do

Quick and easy with no crashes so far and have yet to come across a number it couldn't identify. Only annoying thing is that the geolocation lookup is a bit misleading-obviously that only works for landlines which are few and far between these days. Other then that it's the cats pajamas!

Update-I forgot to mention that the design of the app is rather outdated. Although it is very simple to use, the lack of a "back" button is extremely annoying. I hate that I have to do the extra step of pressing geolocate before I can clear out the number I am done with and enter another one for it to look up.

How could such an obvious necessary function have been overlooked? It's not like the rest of the app was so intricate and detailed that the developer was overwhelmed and forgot to add it in there, this app has literally like 2 things it can do. How hard would it have been to add a third function; the back/clear button?!

No ads and fast, but...

There are no ads (so far) and it seems fast, but it always quickly returns only a blank caller ID. In the years I’ve had it, I think it may have identified one number. But at least it doesn’t try to pawn me off on a subscription ID, personal info/history service like all the rest do.

Callers with non-commercial legitimate intent should not block their ID’s, or at least unblock it for personal calls. All numbers should be associated with an easily identifiable ID/owner. If they block it, then we should all practice not answering such calls. They’d soon stop waking us and unnecessarily disrupting our days. As long as they get someone to pick up, they get paid; even more if you buy whatever they’re selling. Even if one person in 2 dozen answers, and one in 50 go for their deal, it’s worth it to them.

That our congress opted to exempt political calls from Do-Not-Call list regulations was a travesty, and an example of the weaknesses and perversions in our otherwise plodding but sometimes effective government system. If only we could find enough politicians with the guts to separate cash from elections, how much more beautiful and true-to-intent our Constitution would really be.
