About
Large Print Tuner is a tuner for guitar and other string instruments that you can read without glasses. One big note fills the screen, the needle is large and clear, and the tuner says in words what to do: tighten the string, loosen it, or "In tune".
READ IT AT A GLANCE
The note is shown in huge letters with its octave. Under it, the difference in cents and a plain word: flat or sharp. Flat and sharp also differ by the side of the dial and by an arrow, not by colour alone. When a string is in tune, the needle stands in the middle, the word "In tune" appears with a check mark, and the phone gives a short vibration.
TUNES THE GUITAR FOR YOU
Pluck a string: the tuner finds which one you played and lights it up on the headstock picture. A string held in tune gets a check mark, so you can see which ones are done. A badly out-of-tune string can be picked by touching it. Standard tuning, half step down, Drop D, DADGAD, Open G, Open D and the Russian seven-string guitar are all included.
BY EAR, WITHOUT THE MICROPHONE
Touch a string and the phone plays its note until you touch it again. Tune by ear against it, for every instrument, free. A tuner that also works when you would rather not turn the microphone on.
THE SOUND STAYS ON YOUR PHONE
The tuner listens only while it is on the screen. Nothing is recorded, nothing is saved, and the sound never leaves your phone.
FOR EVERY STRING INSTRUMENT
With one payment the tuner also listens to bass guitar (4 and 5 strings), ukulele, violin, viola, cello, double bass, mandolin, banjo, balalaika and domra, and to any note with the chromatic tuner. The guitar and tuning by ear stay free for ever. It is a single payment, not a subscription.
