Verdict

The call

The clearest difference is price: FrequencyCat at Free against Pixel Music's $5.99. FrequencyCat also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 82%). Pixel Music's advantage is update cadence (every 8 months vs every 40 months) and ratings volume (7 vs 1). On ads and in-app purchases there is nothing between them.
