Verdict
The clearest difference is update cadence: Popcoach at every 4 days against Union Three's every 3 weeks. Popcoach also leads on monetization model (free vs ad-supported). Union Three's advantage is ratings volume (259 vs 3) and iOS requirement (16.0 vs 26.0). On price, rating, review sentiment and ads there is nothing between them.
