The public void is designed to expose you to views and opinions you might not otherwise run across. In the public void we communicate entirely through voice. You make audio recordings and send them out for other users to hear. After 100-500 people hear your recording it is deleted and removed forever. This app gives what others can't in that it offers anonymity between users. That way everyone has the chance to be heard. Had a bad day at work? Tell us about it! Had a great idea you just need to share? Fantastic we want to hear! Need to rant about dumb things in life? Great, thats what this is here for!

Verdict
The clearest difference is review sentiment: The Public Void at 100% against Mathetis's 50%. The Public Void also leads on update cadence (every 2 weeks vs every 3 months) and rating (5.0 vs 4.8). Mathetis's advantage is ratings volume (26 vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.
