Verdict
The clearest difference is update cadence: Fast AAC at every 3 days against Avaz AAC's every 4 months. Fast AAC also leads on monetization model (free vs free with in-app purchases) and review sentiment (80% vs 60%). Avaz AAC's advantage is ratings volume (316 vs 8) and iOS requirement (14.0 vs 17). On price, ads, in-app purchases and device support there is nothing between them.
