Verdict
The clearest difference is in-app purchases: KNEW at none against BeConfident's 9. KNEW also leads on ads (none vs shown) and rating (5.0 vs 4.8). BeConfident's advantage is update cadence (every 3 days vs every 6 weeks) and ratings volume (861 vs 1). On price, device support and iOS requirement there is nothing between them.
