Rank history
The Vector Calculator Math Physics app by Francesco Grassi (Education) is currently holding steady across three markets on the App Store Top Paid chart: #16 in Mauritania, #40 in Mongolia, and #76 in Bolivia, all with zero movement from the previous period. Its all-time peak was a strong #2 on August 25, 2026, and over the last 30 days it has averaged around #15, reflecting solid mid-tier performance in the recent weeks. Current standings sit below both the 30-day best of #2 and the 30-day average of #15, suggesting a mild pullback from its earlier highs, although the flat (0) changes across all listings indicate chart positions have now stabilized. Overall, the app remains a consistent presence on the App Store but has stepped back somewhat from its peak momentum.
