App Details Tracker: Google Play + App Store, updates and ratings

Store data for Android and iOS apps in one row format: rating, rating count, star histogram, installs (Google Play), version, update date, release notes, size, minimum OS, age rating, price. Put competitors' apps in one list, schedule it, and switch on onlyChanges: you then get (and pay for) only apps that released a new version, moved in rating, passed an install milestone or changed price.

Typical uses: competitor update tracking for app marketers and ASO · rating watch for your own apps on both stores · investor and analyst app dashboards.

Same run, WhatsApp on the App Store: version 26.41.74 from 2026-10-19, rating 4.7 from 18,820,070 ratings, 411.2 MB, iOS 15.1 or later. A second run with onlyChanges right after: 0 apps reported, 3 unchanged, nothing charged.

What counts as a change

New version · rating move ≥ ratingChangeStep (default 0.01) · higher Google Play install bucket · title change · price change. Each reported row has changes[], previous and ratingCountDelta (new ratings since the last run).

Pricing

Pay per event: $0.003 per app reported on the free plan, −10/−20/−30 % on higher Apify plans. Unchanged apps in monitoring mode, not-found and failed apps are never charged.

Data, fair use and limits

• Reads only the public app pages (play.google.com/store/apps/details, apps.apple.com/<country>/app/…), which robots.txt allows. No search endpoints, no private APIs, no login.
• No personal data: developer e-mail, address and phone shown on store pages are never read; only the published developer/seller name.
• Google Play shows "Varies with device" for some apps instead of one version (version: null, versionNote says so). Installs are Google's buckets (installsMin) plus Google's own estimate; Apple publishes no installs.
• Ratings and versions differ per country; use country per run.
