Story behind the app

RoboStopper was born out of the developers' frustration at continually being interrupted by spam calls, and because existing tools were using inadequate call blocking mechanisms.

RoboStopper was built as a cross-platform spam call blocker that works for all major phone carriers in the US and gives people the peace of mind that when the phone rings, it's somebody they want to talk to.

What do people think?

I've had A LOT of these types of apps; but, OMG!! This one really works! I used to get tons of calls every day - spam, fraud, telemarketers! The other apps would usually block the calls, but they were still able to leave voice mails if they wanted to. Ever since I installed Robostopper, I haven't received any more of these calls. I also don't get any voicemail messages because this app really does block the calls completely! What a relief! I really recommend this app to anyone who is totally sick and tired of getting spam calls!
