Call blocking doesn't work because there are
TRILLIONS (seriously) of possible phone numbers
that scammers, spammers, and unwanted callers can use. It is
impossible to block all of them.
So we created imp based on a different question:
who do you want to hear from?
The answer is simple: your friends, family, and other people you
This is why imp focuses on your smartphone contacts as the place
to start from.
At setup, imp uses your smartphone contacts to automagically
create a Greenlist - a list of contacts that can then grow and
change over time.
The result is that your phone only rings when its a caller you
want to speak to.
And everyone else is just dealt with, silently.
