How to use & support

Start with 10 questions.

1. Start a round from the home screen. Select one or more strings to practice in Settings.
2. Choose the highlighted position's note name from two buttons. String 1 is at the top, string 6 at the bottom. Fret 0 means an open string.
3. Each question has a 30-second limit. Correct answers in under 10 seconds count as mastered, earning points and combos.
4. After 10 questions, check your mastery rate, reaction time, and best combo, then practice again or review.

Fretomo covers a six-string guitar in standard tuning, from open strings to fret 12. Strings 6 to 1 are E, A, D, G, B, E. Other tunings and bass-specific questions are not currently supported.

Read the five hint stages.

The question's note name stays hidden until you answer. A new clue appears every five seconds.

1. 25 seconds left: Yellow C notes help you locate your position.
2. 20 seconds left: A local C major shape appears across four nearby frets. Purple degrees 1, 3, 5, and 7 belong to Cmaj7. Pink degrees 2, 4, and 6 are the other scale notes.
3. 15 seconds left: Pink lines connect matching note names on other strings. ↗ means an octave higher, ↙ an octave lower, and = the same pitch. Connections beyond the enlarged view can be seen in the full board view.
4. 10 seconds left: A green ring marks a nearby different natural note on the same string.
5. 5 seconds left: Count the fret distance from that reference note. Each fret is one semitone.

C major is a learning reference, not a detected song key or a prescribed fingering. The colors do not imply that every scale note, including degree 4 (F), is always stable over Cmaj7. For sharp or flat questions, use the distance from nearby scale notes.

A matching note name can have a different pitch. Fret 0 and fret 12 share a note name, one octave apart.

Review builds on your history.

A wrong answer, a timeout, or a correct answer taking 10 seconds or more marks the position for review. Tricky positions can reappear a little later in a regular round. Review mode focuses on those positions.

A position leaves review when more than 80% of its cumulative answers are correct in under 10 seconds. Exactly 80% is still in review. A position returns if its rate later falls to 80% or below.
