Check back tomorrow — we need at least two days of data to draw a trend.
iGraphmatica by Keith Hertzer currently holds its strongest position in the App Store Education category on the Top Paid chart in Bolivia at #44, which also represents the app's best rank across the reported countries. It maintains secondary visibility in Guatemala, appearing twice at #75 and once at #92 on the Top Paid chart, while also ranking #89 in Saint Vincent and the Grenadines and #98 in Ecuador. All of the app's current chart appearances are concentrated in the Top Paid segment of smaller Latin American and Caribbean markets, with positions ranging from #44 to #98. With no movement data provided for these entries, the trajectory cannot be confirmed, but the presence of duplicate entries showing identical ranks suggests the app is holding steady in these markets.
