Rank history
Code Analyzer — 卿 徐 (Developer Tools) recently hit its all-time peak of #6 on the App Store on 2026-07-30, and the best rank over the last 30 days is also #6, with a 30-day average of #21. Current chart positions are notably weaker than the peak: the app sits at #22 in São Tomé and Príncipe (Top Free, unchanged), #30 in Belarus (down 4), #55 in São Tomé and Príncipe (up 2), #65 in Bahrain (down 13), and #68 in Bulgaria (down a steep 36). The mixed but mostly negative movement — especially the sharp drop in Bulgaria — indicates the app is sliding back down from its recent peak rather than sustaining top-tier visibility. Overall, the trajectory is one of post-peak decline, though it still holds mid-tier Top Free ranks across several smaller markets.
