Even their App Store description is vague. It seems like some kind of forum?

  Home to a spirited exchange of ideas without insults, Ceasefire helps you cut through the noise in a world of diverse views and insights.
  
  Polarization is increasing. The result is pointless bitter arguments, personal attacks, and tribal point-scoring instead of the productive conversations we could be having. It’s clear we need better tools to change this.
  
  Ceasefire is our solution. Every feature is designed for the best experience possible, whether you’re participating or just reading. This includes:
  
  - A focus placed on the issues at hand, preventing the usual popularity contest and its toxic incentives.
  
  - Discussion formats and moderated guidelines that ensure your time is well spent, e.g. rudeness/hostility is prohibited.
  
  - The option to subscribe to topics that matter to you and block those that don’t.
  
  - 'Deltas', which are awarded/received when new insight is gained.

Ah, deltas—must be inspired by the changemyview subreddit.

I wonder how much it relies on having good human moderators. I also wonder how users are incentivized to give deltas only to opponents who have persuaded them, instead of to people they already agreed with. I think in the changemyview subreddit, you give deltas in comment replies, and there I guess it would look obviously silly if you gave deltas to those who agreed with you; that may be a simple resolution for that particular issue.

I wonder if it would be enough to have global moderators create "issues" like: - Do you like Havarti or Cheddar? - Do you support using metric or imperial as a standard in the USA? - Do you ... ... ...

Have the users fill out these answers on profile creation (the ones you don't answer you can't participate in) - and if you contribute on a specific topic and assign a delta to somebody with the opposite viewpoint, the answer you put on your profile gets swapped? You could track how often someone changes a topic on their profile to see if they're "flippy floppy" or if they're fairly hard-stanced on the issue.

You'd still have to have moderation to make sure you don't have people with profile-marked anti-topics making posts supporting the viewpoints.
