Practice
How the app listens to your guitar, which exercises use it, the calibration that makes it accurate, and what to do when it hears nothing.
Some exercises don't just show you what to play, they check it. Switch on Pitch Detect and the app listens to your guitar through a microphone or an audio interface, works out which note came out, and scores it against what was on screen. It's the difference between an exercise you tick off and an exercise that argues with you.
The button sits with the playback controls and turns green while the app is listening.
None of this is required. Every exercise can be practised with detection off, and your points come from the time you log, not from how accurately you played. Detection changes the exercise, not the reward.
Two things it deliberately doesn't listen to. The fretboard drills where you're asked to click the note on screen work by mouse or finger, on purpose, so they're usable on a train. And every hunt has a manual escape: you can tick an octave or a chord tone yourself and skip to the next target when you've found it, which is how the hunts work with the mic off.
Worth being blunt about this, because the green ticks are persuasive and they shouldn't be.
All the app does is measure pitch. It has no opinion on whether you sounded good. A note played with a dead, choked tone, dragged half a beat late, with three other strings buzzing underneath, is a hit as far as detection is concerned — it heard the right frequency. That is not the same as playing it right.
It's also fooled in both directions:
So treat the score the way you'd treat a metronome: a useful second opinion on one narrow question, not a verdict on your playing. If your ear says a run was sloppy and the screen says 98%, your ear is right. If the screen says you missed a note you know you nailed, play it again and listen — if it sounded good, it was good, and the software was wrong.
Detection is a tool for catching wrong notes when you're learning something new and can't yet hear your own mistakes. It is not a replacement for learning to hear them. The goal is to need it less over time, not to chase a higher percentage.
The first time an exercise needs it, you get a Mic Tracking prompt with Enable Mic and Skip. Choosing to enable runs Guitar Calibration, a short wizard that only has to be done once per setup.
Audio Interface if it's plugged into a USB or Thunderbolt box, Microphone if you're playing acoustically into a laptop or USB mic
The browser asks once. Say yes, or nothing downstream works
A Signal Level meter turns green when you're loud enough. Drag the gain, or let the automatic setting listen to you play and pick it
You're asked for all six, one at a time, so the app learns how far your guitar sits from concert pitch and stops calling a slightly flat G an F#
The summary shows the offset it measured per string. That's it, saved
Calibrate in the room and on the gear you actually practise on. A calibration done on headphones in a quiet flat is not the calibration you want on a loud amp.
Next to the Pitch Detect button is a small chevron with the things you need occasionally rather than daily.

Detection compares what it hears against what it expects, so it has to know how your guitar is tuned. The tuning button in the same row covers Standard, Drop D, Half Step Down, Whole Step Down, Drop C#/Db, Drop C, Open D, Open G and DADGAD, and the targets shift to match, so playing where you'd naturally play still counts.
Some exercises lock the tuning, because the drill only makes sense in the tuning it was written for. When it's locked the button says so instead of opening.
Learning Path exams that grade your playing require detection and won't let you skip past the prompt: the module can't mark you on something it can't hear. Everywhere else, skipping is a normal, supported way to use the app.
If detection is fighting you for more than a couple of minutes, turn it off and keep playing. A logged session with the mic off is worth exactly as much as one with it on.
Do I need an audio interface?
No. A laptop microphone works for most drills. An interface is cleaner, quieter and faster, and the desktop app makes it faster still
Does detection change my points?
No. Points come from the time you log and your healthy habits. Accuracy affects the exercise's own score and its stars, not your level
Why does it miss notes I definitely played?
Usually calibration or tuning. Retune, then Recalibrate. Fast passages on a distorted tone through a room mic are also genuinely hard to read
Can I use it on my phone?
Yes, the browser mic path works on mobile, though a phone in a loud room is the hardest case there is
It hears my amp or backing track too
It will. Play through headphones where you can, and keep the room quiet during hunts
Can I practise a mic exercise without a mic?
Yes. Hunts let you tick what you've found by hand and skip on, and tablature exercises simply play through unscored
