Review themes: 4 US App Store written reviews, updated Nov 22, 2025–Sep 13, 2026. Collected Nov 4, 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 11, 2026.
