Five companions for your moments of music.
Listening, keeping time, tuning, analysing and adjusting. You will find each tool at the bottom of the screen, ready to explore at your own pace.
Take the time to listen.
Find the sixteen harmonics on the wheel, from the low H1 to the high H16. Every note carries its name. Touch it to hear a real Alphorn.
Keep your finger down to hold the sound. You can slide it off the note: the sound carries on until you let go.
- 16 harmonics
- 64 recorded sounds, in F, F♯, C and G
- Adjustable length, fade and reverb
- Two sound sets: Dry and Room

Find your tempo. Keep the thread.
Choose from seven time signatures and four subdivisions, from 30 to 240 beats per minute. You can also tap your tempo. The app takes the average of your last five taps.
Let the swinging horn, the lit-up beats or the score in treble clef guide you: the note lights up at the right moment. Choose the cue that helps you play with ease. The app remembers your choices from one session to the next.
- 30 to 240 BPM
- Accent on the first beat
- Volume separate from the Tuner’s

Find your bearings for playing in tune.
With your permission, the microphone listens as soon as you open the Pitch tuner. Play a held note. You see its harmonic, its difference and how long you hold it.
Choose a small hold target to practise your breathing. It starts at ten seconds. You can set it anywhere from one to sixty seconds.

Take a close look at your playing.
The pitch curve shows the last few seconds of your playing (3, 6, 12 or 30 seconds), with a zoom of your choice. Touch the curve to read a point or pause it. The 16 notes mode shows how in tune each harmonic you played was.
The summary gives the average, the deviation, the percentage of time in tune, the hold time and the steadiness. The Harmonics tab shows the strength of the first 8 harmonics of your sound: it helps you hear whether it is bright, round or balanced.

Your instrument. Your bearings.
Choose a horn in F, F♯, C or G, the tuning reference (Natural harmonics or Equal temperament) and a reference A between 430 and 455 hertz. Set the reference sound: volume, length, fade, attack, reverb, bass, power and metronome click. Also adjust your in-tune zone, the microphone sensitivity and the listening time.
To match the reference to your instrument, choose “Tune the app to your horn”. The mini guide in the settings then helps you lengthen or shorten your Alphorn.

Find the notes in your own language.
In German, C, E and G are the notes you already know. B flat is written B there, and B natural is written H. In English, these two notes are written B♭ and B.
The app automatically picks the language of your phone or browser: French, German, Italian or English, and French for any other language. You can always change it by hand in the Settings, and your choice is remembered.

No network, no problem.
AlphornTuner keeps a copy on your phone and works without a network. There are two sound sets: Set 1 “Dry” (clean sounds) and Set 2 “Room” (sounds with the acoustics of a room).
Set 2 can be kept offline as an option, for about 24 MB.
- Works without a network
- Set 1 · Dry
- Set 2 · Room (24 MB offline)
