Migraine Tracker - Brain Twin

The Migraine Tracker - Brain Twin app by Nordic Brain Tech is currently strongest in Norway's Top Grossing chart at #4, the same position it hit on 2026-06-20, having just climbed back up (+3). Its performance is mixed elsewhere: it has slipped to #21 in Finland's Top Grossing chart (down 4-5 places) and dropped to #21 in Norway's Top Free chart (-9), while improving to #47 (+2) in another Norway Top Free slot and holding steady at #71 in Finland's Top Free. With a 30-day best of #4 and average of #6, the app is sitting at its all-time peak but shows divergent momentum across markets, climbing in Top Grossing while losing ground on the free side.
