Rank history
The AMC Buoyage System (IALA) app, in the Education category, is currently holding flat positions across the App Store's Top Paid charts with no meaningful momentum. Its peak rank remains #28, achieved on 2026-06-23, and that level is matched by its best position over the last 30 days (average also #28), indicating a stable but low-visibility trajectory. The standout current position is #28 in Papua New Guinea (Top Paid, unchanged), tying its all-time peak, while it sits at #46 in Georgia (+1), #64 in Montenegro (0), and #71 in Serbia (0). Movement is essentially static: only Georgia showed a single-place improvement, and the other three markets registered zero change. Overall, the app is steady at modest ranks in four small markets with no signs of climbing or falling.
