Research shows fluency in the foundation skills is critical to reading comprehension. Our apps are designed for and tested by typical and special needs children.

We collect NO private information in our app, and our apps do not allow unrestricted web access. Inferencing is a key component of reading comprehension. If you can't infer fluently, you can't understand the story. Help your child now by getting started with our Inference Ace app. While you're at it, check out our other apps that target WH questions, identifying inference clues and identifying the main idea of a sentence or paragraph. We take customer service very seriously! If you ever have a problem or find that we've missed something, contact us at our website and we will do our best to fix the problem. ** Note: Inference Ace and Inference Clues intentionally use similar data sets. However, different skills are targeted. Also, when working through this app, you will encounter different variants of the same examples many times as we teach our players to derive multiple inferences from a single sentence -- just like expert readers do. This is an intentional feature, not a bug :-)

Verdict
The clearest difference is review sentiment: Inference Ace at 89% against Comprehend's 0%. Inference Ace also leads on device support (3 vs 1) and ratings volume (21 vs 6). Comprehend's advantage is rating (4.5 vs 3.6) and update cadence (every 6 weeks vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Inference Ace 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, 4.5 against 3.6. Both are backed by a comparable volume of ratings — 21 and 6 respectively. Written reviews complicate that: 89% of Inference Ace'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.
Inference Ace ships an update every 7 months, Comprehend every 6 weeks. The most recent releases landed on October 15, 2026 and October 7, 2026 respectively.
