Phenomenal app for identifying unknown callers. I've been using a different app for years, and stuck with it out of inertia. But I eventually acknowledged it wasn't providing accurate caller identity in most cases, and looked for something different. NumberBox is very simple; it does one job - very well - and doesn't try to do any more. No ads, and no spinning for 60 seconds while it (pretends to) find all sorts of other facts about the caller I don't really care about. A++

Nonsense names given. Sometimes it's a one word nonsense word. When looking up numbers I already know, they don't match the results here. I think one out of every 10 is accurate but that's not too helpful if you don't already know the answer. I give it 2 stars for interface.

I highly recommend this app for finding the name of a person that belongs to what person I rarely, if ever, leave an app review... however, this app deserves all 5 stars I gave it b/c it actually WORKS!!! hallelujah - thank you so much to the app developers who made this app and made it to provide the name of the owner of the phone.
