Verdict
The clearest difference is rating: Comprehend at 5.0 against Main Idea's 3.7. Comprehend also leads on update cadence (every 6 weeks vs every 22 months).

Both are free to download. Main Idea sells 3 one-off in-app purchases and Comprehend sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
Comprehend holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 3 and 5 respectively.
