Developer portfolio analysis

Automatically summarizes public App Store metadata such as categories, rating volume, star ratings, release dates, and pricing for competitor research and product planning. The DeepSeek section is generated on demand when the API is configured; otherwise only rule-based analysis is shown.

DeepSeek AI analysis

Runs on demand so the initial page load stays fast.

Review the rule-based cards first, then generate the AI readout. It usually takes 10-40 seconds.

Product direction

Ratings and reputation

Weighted average and head effects

  • The weighted and simple averages differ meaningfully, indicating that high-review apps strongly shape perception.
  • 1 apps have no public rating data, so long-tail performance is underrepresented.

Reputation risk proxy

Low ratings and thin samples (API has no review text)

The iTunes Search API does not provide review text. This card uses low star ratings with enough review volume as a proxy, and separately highlights apps with thin samples.

  • Low-rating watchlist (at least 80 ratings and below 4.0 stars): "Love Signal: D-Mate" 3.2★. Use App Store Connect exports or third-party data for semantic review analysis.
  • Thin rating samples (under 50 ratings): "누가 그녀를 죽였나", "세모캐 : 세상의 모든 캐릭터(GIRL)", "약장사". Star ratings can swing heavily until more feedback arrives.

Release and lifecycle

Listing age span

The earliest listed app is "Click! 그 남자를 공략하시겠습니까?", while the newest or most recent listing signal is "Puppet Boss". The span is a proxy for long-term iteration capacity.

  • Earliest record in this dataset: 2015 (Click! 그 남자를 공략하시겠습니까?).
  • Newer app signal: 2022 (Puppet Boss).

Reference points for builders

Reusable research angles

These takeaways are based on public metadata and are useful for competitor research or portfolio planning. Deeper conclusions require downloads, revenue, and review text.

  • Study the category mix: 1 categories show whether a main-category plus extension structure matches your resources.
  • Compare reputation structure: weighted 4.43 stars vs. the leading app "Marked by King Bs" and its review volume.
  • For similar tools, prioritize review mining on lower-rated apps to find functional gaps; this requires store reviews or third-party data.

Rule-based cards use iTunes Search API data. DeepSeek generates its readout from the same public data and should be treated as directional research.
