Guitar Tuner & Coach: Afinora

Tune in seconds, hold the tempo, and find out what actually goes wrong when you play.

Afinora is the tuner, the metronome and the practice room for guitar, bass, ukulele, violin and more. A precise chromatic tuner, a professional metronome, scales and chords in your own tuning, training that listens to every note, and a studio to record yourself.

TUNER
• Real-time pitch detection, processed on the device
• 10 instruments: guitar, 7-string guitar, bass, ukulele, Venezuelan cuatro, violin, viola, cello, mandolin and banjo
• Over 30 standard and alternate tunings, plus tunings you build yourself
• A reference tone on any string, and six A4 references from 432 to 442 Hz
• Reads an unplugged electric guitar

TECHNIQUE TRAINING
This is the part that listens back. Pick a scale shape, set a tempo, and play it against the metronome. Afinora grades every single note as it arrives: clean, late, or missed. Not a score at the end of the song, but a verdict per note, so you can see that it is always the same two notes of the shape that you rush.
• Pitch and timing measured separately, so you know which one failed
• Built-in scale patterns, or import your own exercise from plain text
• Loops that raise the tempo on their own as you keep up
• A history per scale, so progress is a number and not a feeling

STUDIO
• Import a backing track, mark a section, loop it and slow it down
• Record yourself over it, as audio or as video
• Save takes to your gallery or share them

METRONOME
• An audio engine that does not drift
• 30 to 300 BPM with tap tempo
• Time signatures from 2/4 to 12/8, subdivisions down to sixteenths
• Accent or mute any beat of the bar with a tap

CHORDS AND SCALES
• 20 scales and 20 chords, drawn on the neck of your instrument in your tuning
• The whole neck, up to 24 frets, with a fullscreen view
• Notes or degrees, and chord voicings including barre shapes
• The chords that belong to the key you are looking at

EAR TRAINING
• Notes and intervals, answered on your real instrument rather than by tapping a button

WITH A USB AUDIO INTERFACE
Plug your instrument in and every note reads exactly. A wired signal is what makes note-by-note grading trustworthy: an unamplified electric is not a signal a detector can read reliably, and a room microphone drops notes as soon as there is noise. Afinora detects the interface, compensates its latency, and tells you it is connected. Acoustic instruments can train through the phone microphone instead.

PRIVATE BY DEFAULT
No account, no ads, no tracking. Audio used for tuning and training is analysed on the device as it arrives and is never recorded or uploaded. Studio recordings stay on your phone unless you share them yourself.

FREE AND PRO
Afinora opens with 5 days of full access. After that, the free version keeps one instrument of your choice, the major and minor scales, and 5 Studio recordings. Afinora Pro is a one-time purchase, not a subscription, and unlocks everything permanently.

Available in 9 languages: English, Spanish, Italian, French, Portuguese, German, Japanese, Chinese and Russian.
