Comic Book Scanner - Gradr

By Julian Praest

Scan comic covers or barcodes for candidate IDs and estimated grades/values, then organise a collection.

Our take

Use it for preliminary research rather than authentication.

Guided condition photos and saved purchase notes connect identification with inventory.

Keep in mind: The publisher explicitly says estimates are nonprofessional and may be wrong; they are not certification or appraisal.

What you can do

  • Scan a comic cover or barcode
  • Review optional three-photo condition suggestions
  • Save confirmed candidates and notes in a collection

Review themes: 3 US App Store written reviews, updated Mar 29, 2026–Oct 21, 2026. Collected Nov 6, 2026.

Review sources & grouping details

These themes use the completed local review collection and Codex analysis: the latest accessible written reviews within one year, up to 500 per app. This is an accessible sample, not a guarantee of all reviews or a measure of all users.

The feed does not identify each review’s platform. Its date is an update timestamp and may reflect an edited review. Versions shown belong to individual reviews; reported limitations are not verified current-version behavior.

Codex grouped explicit opinions from the review text, with original-text evidence retained. Counts use distinct review IDs, independently of star rating. A review may appear in several topics. The three most-mentioned topics per side are shown first; where more are available, expand the list to see every topic supported by at least three reviews. Group summaries describe recurring aspects across the group; individual examples retain their own context and do not stand in for the whole group. 0 reviews were too general, unclear or off-topic to assign a specific theme. Example summaries are paraphrases; the labeled excerpts are original review text. Analysis updated Nov 10, 2026.
