Verdict

The call

The clearest difference is review sentiment: Main Idea at 71% against Comprehend's 0%. Main Idea also leads on device support (3 vs 1) and ratings volume (19 vs 5). Comprehend's advantage is rating (5.0 vs 3.8) and update cadence (every 6 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
