Verdict
The clearest difference is price: Lexar at Free against ChatterBox Pro's $4.99. Lexar also leads on ratings volume (19 vs 1) and iOS requirement (17.0 vs 26.0). ChatterBox Pro's advantage is rating (5.0 vs 4.1) and update cadence (every 5 days vs every 3 weeks). On ads, in-app purchases and device support there is nothing between them.
