Verdict
The clearest difference is in-app purchases: Subscription Sentinel at none against Subo's 6. Subscription Sentinel also leads on rating (5.0 vs 4.8) and iOS requirement (17.0 vs 26.0). Subo's advantage is ratings volume (74 vs 1). On price, ads and device support there is nothing between them.
