Verdict
The clearest difference is in-app purchases: poly player at none against Nu's 2. poly player also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 3 months). Nu's advantage is ratings volume (62 vs 9) and review sentiment (50% vs 42%). On price, rating, monetization model and device support there is nothing between them.
