Robokiller's spamcall recording features

It's estimated that people around US receive 190 million spam and robocalls per day.

Robokiller is one of the most famous mobile apps helping people to not only stop spam calls, but to get revenge on the callers.

We've been a crucial part of Robokiller's design team for over 3 years and designed most of their main features. In just 18 months, Robokiller managed to gain around 1,5 million monthly paid users, and eventually got acquired by a public company.
