Verdict

The call

The clearest difference is in-app purchases: AudioVisualizer at none against AloneQuartet's 1. AudioVisualizer also leads on ads (none vs shown) and update cadence (every 8 days vs monthly). AloneQuartet's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 18.5). On price there is nothing between them.
