Verdict
The clearest difference is in-app purchases: Super Focus Time at none against Jin Timer's 1. Super Focus Time also leads on update cadence (every 2 days vs fortnightly) and iOS requirement (12.0 vs 16.2). Jin Timer's advantage is ads (none vs shown). On price and device support there is nothing between them.
