# Main Idea vs Comprehend

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). Main Idea's advantage is review sentiment (42% vs 0%) and device support (3 vs 1). On price, ratings volume, ads and in-app purchases there is nothing between them.

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. Written reviews complicate that: 42% of Main Idea's written reviews are positive against 0% of Comprehend's, so the app with the better star average is not the one people write more warmly about.

Main Idea ships an update every 22 months, Comprehend every 6 weeks. The most recent releases landed on June 3, 2026 and July 30, 2026 respectively.
