About Us

AppPrice Radar (appradar.top) is an independent App Store cross-region price comparison project. We help people compare public list prices for the same app across regions and spot relatively lower shelves—not a purchasing agent, and not a toolkit for abusing region rules.

What this project is

We focus on one job: turn public App Store prices for curated apps into daily snapshots you can browse and compare. The bilingual UI, guides, rankings, and change feed exist to make that comparison clearer.

This is an independent project with no official affiliation with Apple and no representation of any app developer. Names, icons, and store links belong to their respective rights holders.

Where the data comes from

Prices and app metadata come from public App Store pages in each region. We collect and store daily snapshots; we do not run a live Apple query every time you open a page.

The catalog currently covers about 20 App Store regions and about 100 curated apps (app list prices plus selected subscription tiers). Coverage can change over time; on-page stats follow the current snapshot.

Methodology

• Local currency preserved: we store regional amounts and currencies as collected, without rewriting them into another currency at ingest.
• Display conversion: reference amounts (for example CNY) use the snapshot day’s FX rates so historical series do not accumulate multi-step conversion noise.
• Subscription matching: we align products across regions by name and billing period; when mapping is unreliable we mark unmatched instead of guessing a price.
• Honesty red lines: we never invent prices; a failed collection does not write fabricated values; each daily snapshot is treated as an immutable historical record—we do not “beautify” past numbers after the fact.
• Free apps: when the app itself is free, we still show membership/subscription tier prices when those products are in the catalog.

What we do not do

• We do not resell apps, process payments, or handle transaction funds.
• We do not provide guidance beyond general region-switch tutorials for evading payments, faking billing addresses, or other platform-policy abuse.
• Prices are for reference only: availability, taxes, and settlement amounts follow your App Store account and checkout page.
• We do not claim real-time data; stale snapshots are flagged in the product UI where relevant.
