# 萤火虫 vs 53Hz

The clearest difference is rating: 53Hz at 3.8 against 萤火虫's 1.0. 53Hz also leads on update cadence (every 2 days vs every 5 weeks) and ratings volume (4 vs 1). 萤火虫's advantage is iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
