Verdict
The clearest difference is in-app purchases: ResponderApp at none against ShiftWave's 3. ResponderApp also leads on ads (none vs shown). ShiftWave's advantage is update cadence (every 5 days vs monthly) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.
