iGraphmatica

iGraphmatica by Keith Hertzer is currently holding steady near its all-time peak in the Education category on the App Store. The app achieved its best-ever rank of #41 on 2026-08-02 and has matched that in the last 30 days, with an average position of #43. Its standout current placement is #41 on Bolivia's Top Paid chart (unchanged), followed by #77 in Guatemala, #89 in both Guatemala and Saint Vincent and the Grenadines, and #95 in Ecuador. With zero movement across all listed country charts, the app's overall trajectory is flat and stable rather than climbing or falling. The app's reach remains limited to smaller markets with no presence in major charts.
