Verdict
The clearest difference is ads: SDoH Challenge at none against Pebble Chat's shown. SDoH Challenge also leads on rating (5.0 vs 4.8) and monetization model (free vs ad-supported). Pebble Chat's advantage is update cadence (every 4 days vs every 3 months) and ratings volume (6 vs 1). On price and in-app purchases there is nothing between them.
