Read full descriptionHide full description
Fretboard Map helps beginning guitarists understand the fretboard visually. Explore the CAGED system, shell voicings, chord tones, and an interactive note map to move beyond open chords and the first three frets. Guided practice paths help you learn roots, octaves, CAGED shapes, and fretboard connections. Hear the notes you are learning with separate recorded acoustic and electric guitar sounds. Play a chord together or hear its tones one at a time as an arpeggio. The acoustic sound uses nylon-string guitar recordings; the electric sound uses pickup recordings with gentle amplifier processing. Both sounds are included for offline playback. Key features: - Diatonic chord diagrams across seven modes, with chord and arpeggio playback - All five CAGED shapes and shell voicings - Triads and major, minor, dominant, and half-diminished seventh chords - Switch between note names and scale degrees - Interactive note learning and guided daily practice - Acoustic and electric guitar playback for notes, chords, and arpeggios - Built-in tuner with 440 Hz, 432 Hz, and 430 Hz reference standards - Landscape layouts for iPhone and iPad - English and Simplified Chinese interfaces No account is required. Build your understanding of chord shapes, note locations, and connections across the guitar neck.

Train rhythm like a skill: hear it, read it, tap it in time. Rhythm Bench is a rhythm trainer and metronome for musicians, drummers, music students and teachers. More than 30 exercises cover pulse, subdivisions, syncopation, tuplets, odd meters, sight reading, polyrhythms and independence—with early/late timing feedback you can actually practise from. RHYTHM TRAINER WITH REAL TIMING FEEDBACK See whether each tap was early, on time or late. Session summaries show timing bias, consistency and drift so you know what to fix—not only whether an answer was correct. SIGHT READING & EAR TRAINING FOR RHYTHM Read rhythms on the staff, tap them against the click, and train dictation and recognition. Build from simple note values to complex patterns without repeating the same drill forever. METRONOME, TEMPO & PRACTICE TOOLS Use a metronome with accents, subdivisions, swing, gap bars, tempo ramps and polymeter. Build speed with the tempo trainer, browse grooves, or tap an idea and turn it into readable notation. GUIDED COURSES + FULL CATALOGUE Follow ten guided paths from pulse through compound meter, syncopation, tuplets, odd meters, polyrhythm and sight-reading fluency—or open the exercise catalogue and build a session around the skill you need. PRIVATE BY DESIGN Works offline for practice. No account or cloud sync of your history. Anonymous Firebase Analytics helps improve the app. Your practice history stays on your device unless you export it. Premium is a one-time unlock (no subscription): remaining curriculum paths, full catalogue and advanced practice tools.

Verdict
The clearest difference is in-app purchases: Fretboard Map at none against Rhythm Trainer's 1. Fretboard Map also leads on update cadence (every 9 days vs monthly). Rhythm Trainer's advantage is iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.
