Verdict
The clearest difference is in-app purchases: Veritas Battery at none against Audio Function Generator's 1. Veritas Battery also leads on update cadence (every 4 days vs every 6 weeks). Audio Function Generator's advantage is rating (4.7 vs 4.2) and ratings volume (2.2K vs 5). On price, ads, device support and iOS requirement there is nothing between them.
