Always know which way is north.
TrueNorth trains the compass you were born with. Through the day it asks “Which way is North?” You point your phone, lock it in, and see how far off you were. No map, no peeking, and your aim gets sharper every time.
Train your inner compass.
The problem
We outsourced our sense of direction to a blue dot.
Constant turn-by-turn means we never build the mental map. TrueNorth flips that with short, frequent reps that rebuild your internal compass.
- 01
Point
A notification asks which way is North. Aim the top of your phone where you think true north is. The live compass stays hidden, so it's all you.
- 02
Lock it in
Commit to your guess and tap Lock it in. No second-guessing, no peeking at a map. Just your gut and the world around you.
- 03
Reveal
See exactly where true north was, your error in degrees (say, “18° too far east”), the cardinal direction you pointed, and a score for the guess.
- 04
Improve
Spaced repetition through your day wires it in. Watch your average error shrink, fastest in the places you move through most.
Features
A real training tool, not a party trick.
Everything here works toward one reliable internal compass you can trust without reaching for your phone.
Spaced-repetition reminders
Pick 15, 30, or 60-minute intervals. Frequent, low-effort reps throughout your day are what make the skill stick.
Accuracy by location
TrueNorth breaks down your results place by place. You'll get noticeably sharper in the spots you frequent, like home, the office, and your usual trail.
True north, not magnetic
We correct for magnetic declination using your GPS position, so you're training against geographic true north, the kind maps actually use.
Streaks & trends
Daily streaks, best guesses, and an improvement trend line keep you honest and show the curve bending in your favor.
Works offline
Compass and declination math run on-device. No signal on the ridge? TrueNorth keeps training anyway.
Privacy-first
Your guesses and locations stay on your device by default. No accounts required, no selling your whereabouts. Ever.

FAQ
Questions, answered.
TrueNorth reads your phone's magnetometer, then corrects for magnetic declination using your GPS position. The angle between magnetic north and geographic (true) north varies by where you are on Earth. We grade you against true north, the same reference paper maps and trail signs use.
No. The compass and sensors only spin up for the few seconds around each guess. Between reminders the app is idle. Even on the 15-minute interval, the footprint is tiny compared with maps or music.
Yes, and that's part of the challenge. Steel and electronics can nudge the magnetometer indoors, so TrueNorth applies on-device calibration and still grades you against true north. Most people find indoor reps the most humbling, and the most useful.
Yes. Your guesses, scores, and location stats stay on your device. No account is required to train, and we never sell or share your whereabouts. Location is used only to derive true north and group accuracy into approximate local areas.
Android ships first. iOS is on the roadmap and follows shortly after launch. Join the waitlist and pick your platform, and we'll ping you the moment your version is ready.
There will be a free tier with everything you need to start training. A small optional upgrade adds deeper stats, unlimited locations, and longer history. No ads, no selling data, ever.
