What it does

Everything you need for unknown calls

Type a number and see every name it is saved under in the community directory. If there is no record, we say so and the lookup is free.

More than 31,000 known spam numbers from public regulator data are labeled as “Suspected spam” while your phone is still ringing.

Block a number with one tap and report unwanted calls so others are warned too.

Find duplicate contacts, contacts without a name or number, and clean them up in one pass.

Export your address book as VCF, CSV or PDF and keep a copy wherever you like.

Your contacts never leave your phone unless you separately choose to share them, and you can undo that at any time.
