Verdict

The call

The clearest difference is in-app purchases: Yapper at none against Korean's 2. Yapper also leads on ads (none vs shown) and update cadence (every 2 days vs every 3 months). Korean's advantage is ratings volume (3.4K vs 8) and device support (4 vs 2). On price and rating there is nothing between them.
