Verdict
The clearest difference is rating: Kotoren at 5.0 against Audio Looper+'s 4.1. Kotoren also leads on review sentiment (95% vs 71%) and iOS requirement (15.0 vs 18.6). Audio Looper+'s advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
