Disk Diag

Disk Diag by Rocky Sand Studio Ltd. recently peaked at #5 on the App Store Top Free charts on September 2, 2026, which also marks its best position over the past 30 days against an average of #38. Currently, the app is positioned across Top Free charts in eight countries, with its strongest showing in Benin at #16, followed by another Benin entry at #42 and Senegal at #45. The remaining positions cluster in the #54–#78 range across Slovakia, Solomon Islands, Brunei, and Mongolia, most showing no change from previous rankings. The gap between its #5 peak and current #16–#78 placements indicates a noticeable pullback from its recent high, though the app retains a foothold in multiple emerging-market charts.
