Northsense: Direction Trainer

Northsense is a 90-second daily exercise for your sense of direction. Every day, the app names a bearing — north, southwest, 47 degrees — and asks you to point your iPhone at it. Tap to lock when you think you're aimed right; we measure the angular error and score the round. Five rounds make a Daily Quest. Keep your average error at 30° or less and your streak counts up. It's not a navigation tool. It's a training game — for hikers, orienteers, sailors, walkers, geocachers, kids learning geography, or anyone who likes a small daily mental warm-up. FOUR MODES • Daily Quest — five rounds, a fresh combination of bearings every day. Build a streak. • Free Practice — pick your own target. Tap as many times as you like. • No-eyes Quest (Pro) — voice prompts and haptics only. Close your eyes and trust your instinct. • Memory Walk (Pro) — face a direction, walk a few steps in any way you like, then point back from memory. Daily Quest and Free Practice are free. Northsense Pro, a one-time in-app purchase, unlocks No-eyes Quest and Memory Walk. PRIVATE BY DESIGN No account. No cloud. No ads, no tracking. Every score stays on your device. Apple's own CoreLocation and CoreMotion frameworks read heading and step data only while you're inside a round. WORKS WITH WHAT YOU HAVE • iPhone with a magnetometer (any model from the last decade). A daily minute. A sharper compass instinct.
