Verdict
The clearest difference is in-app purchases: PerfectFast at none against Nomu's 6. PerfectFast also leads on review sentiment (100% vs 86%). Nomu's advantage is ratings volume (97 vs 8) and update cadence (every 5 days vs every 10 days). On price, rating, ads and monetization model there is nothing between them.
