Verdict
The clearest difference is in-app purchases: Serenus at none against SecTrans's 2. Serenus also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.0). SecTrans's advantage is ads (none vs shown) and update cadence (weekly vs every 3 weeks). On price there is nothing between them.
