RoboStopper is a cross-platform app that blocks all unwanted phone calls, with an optional bypass rate that spammers must pay. No foolhardy blacklists, and more flexibility than iOS’s Silence Unknown Callers so that you don’t miss any important phone calls.

I think it sucks! It blocks all of the incoming calls, not just potential scammers, and it does not save any of the voicemails people have tried to leave me. I've uninstalled it, deleted it and factory reset my phone and I still can't get this application off my device!

Hey PH! Two working dads building an app in our free time that cuts back on the spam phone calls that kept ringing our phones in the middle of those rare special moments with family. We went from concept to cross-platform release in 2 months using a variety of tools (Flutter, Golang, Postgres, Docker and kubernetes), and feel strongly that we’re better than every other option, even iOS’s new Silence Unknown Callers. In the process of development we realized we could also create a mechanism for users to get paid by unwanted callers! RoboStopper is live ready for prime time. For us, it has solved our original spam phone call problem, and we hope it helps you recapture control of your phone number.

Hey! Except this getting paid part, how is that different and/or better from Should I answer? app?

@albert_wolszon Hey Albert, thank you for taking the time to comment. The "Should I Answer?" app, and all other apps like it on Android, use a blacklisting approach to screen calls. This relies on users reporting numbers that should be flagged as spam, which updates an on-device list of spam numbers, and the next time that number calls someone, it is either blocked or displayed as suspicious. RoboStopper is the first app on Android that uses an on-device whitelisting approach that only allows calls through from people that are in your contact list. In the comment below/before yours', Jim Weiler notes the challenges that are introduced with this approach (blocking calls too well), which we mitigate with a variety of modes that give the user control over the timing and level of spam blocking. For our users that used to have an out-of-control problem with spam calls, RoboStopper keeps their phones quiet during the day and allows calls through from their family members and friends. If you have the time, please give RoboStopper a try (7-day free trial!) and let us know what you think.
