IronMark
Know who's calling.
IronMark shows you who's calling before you answer, warns or silences spam calls, and lets you block any number. Names come from address books people choose to share — never showing who shared them — and anyone can unlist their own number.

Who is calling, before you answer
A caller card appears over the ringing screen with the name and whether the number has been reported as spam. If a phone will not allow the card, a notification carries the same thing.
Spam, handled the way you choose
Set spam calls to warn you, to ring silently, or to be rejected outright. Report a number as spam and say why, so the next person knows what kind of call it is.
Where the names come from
If you choose to share your contacts, IronMark uploads the numbers and names in your address book, and that is where caller names come from. It is off unless you turn it on, caller ID works without it, you can switch it off later, and deleting your account deletes what you shared. A name shown is the one most people agree on; IronMark says how many named a number, and never who they were. You can suggest a better one.
Block any number, and look one up
Block a number in one tap, and search any number to see its name and spam reports. After a call, a card lets you name, report or block it while it is fresh.
Your number is yours to take off
Anyone, with or without the app, can unlist their own number by proving it with a code sent to it by SMS. IronMark then erases every name and report held for it and never shows it again.
