Verdict
The clearest difference is in-app purchases: EplvsDriver at none against Audio Function Generator's 1. EplvsDriver also leads on rating (5.0 vs 4.7) and iOS requirement (13.0 vs 15.5). Audio Function Generator's advantage is ratings volume (2.2K vs 1) and device support. On price there is nothing between them.
