Verdict

The call

The clearest difference is in-app purchases: iSpeak at none against Cogni's 9. iSpeak also leads on rating (5.0 vs 4.7). Cogni's advantage is ratings volume (1.7K vs 1) and update cadence (every 9 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
