User Reviews

Users are broadly enthusiastic about Guardian TCG Card Scanner and its potential as a first-of-its-kind tracker, with positive feedback on layout and features. However, multiple reviews converge on recurring problems: bugs and slowness, portfolio management issues, data gaps and mispricings, a cluttered UI, and nonfunctional AI tools. The app shows promise and momentum, but reliability, data accuracy, and UX need significant improvement.

Pros

Strong positive reception and enthusiasm about the app's concept and future.
Innovative, first-of-its-kind concept with clear potential to become the top app for tracking collections.
Well-designed layout and rich tracking features/information that users find useful.
Updates that improve usability and fix bugs, showing ongoing development.

Cons

Persistent bugs and slow performance affecting core features and overall usability.
Portfolio management is difficult (adding/removing cards is buggy).
Incomplete or inaccurate card data and search results (missing items, language mismatches, pricing discrepancies).
Cluttered, hard-to-navigate UI that makes it easy to get lost in the app.
AI grading and sentiment features do not work or are unreliable.
