The app is free to download, and digital material packages for printed textbooks are provided at no extra cost. However, additional products must be purchased and unlocked through a user account. ### Does the app work without an internet connection? Yes, once e-books and accompanying materials are downloaded, they can be accessed offline, though initial account login and content activation require a connection. ### Why can't I access my purchased textbooks? Users report persistent authentication errors and barcode scanning issues that can prevent content from unlocking. If you encounter these, ensure your credentials are correct or contact support. ### Can I edit my notes in the app? The app supports note-taking and text editing tools, but users currently report that a dedicated eraser tool is missing, which can make correcting pen-written notes difficult. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
