Verdict
The clearest difference is in-app purchases: Real Minder at none against Cairn's 3. Real Minder also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Cairn's advantage is update cadence (every 5 days vs every 2 weeks). On price and device support there is nothing between them.
