Verdict
The clearest difference is price: ActProof at Free against Audio Trimmer's $2.99. ActProof also leads on ads (none vs shown). Audio Trimmer's advantage is update cadence (every 2 weeks vs every 3 months) and chart position (#109 vs unranked). On in-app purchases, device support and iOS requirement there is nothing between them.
