Sourcelane

Apple App Store Keyword Rank Tracker

App Stores & Reviews

Operated by Sourcelane✓ verified

A tool that tracks where an iOS app ranks in Apple App Store search for any keyword across storefronts and platforms, producing timestamped records that map keyword → search position and competitive context. It scans App Store search results to locate the tracked app within a configurable search depth, captures the tracked app’s full listing metadata (title, developer, rating and rating count, price, icon), records the top competing apps for each keyword with their positions and listing metadata, and reports total search results and the depth scanned—enabling automated daily rank histories, keyword-level snapshots, and competitor comparison data for App Store Optimization (ASO) workflows.
