Verdict
The clearest difference is review sentiment: 30 CFR by LawStack at 89% against SKC SmartWave's 0%. 30 CFR by LawStack also leads on update cadence (every 2 months vs every 18 months) and ratings volume (7 vs 1). SKC SmartWave's advantage is rating (5.0 vs 3.7) and in-app purchases (none vs 2). On price, ads, device support and iOS requirement there is nothing between them.
