Solfege - Vocal Sight Reading by Oleg Sokolov is currently holding a steady position in the App Store's Music category, sitting at #29–#30 in Côte d'Ivoire's Top Paid chart with essentially no movement over recent observations (change of 0 on the two tracked entries). The app has matched its all-time peak rank of #29, achieved on 2026-07-30, and the last-30-day average (#29) confirms it has been remarkably stable at that level rather than climbing or falling. Its visibility remains narrowly concentrated in a single market — Côte d'Ivoire — with no current presence reported in any other country's charts. Overall, the trajectory is flat and stable, suggesting consistent but geographically limited demand.
