A guitar tuner. The microphone is for pitch only. Nothing is recorded. Less accurate than a clip-on, especially in noise.
Play a string, see the note and how far it is from in tune. The sound stays on the phone; nothing is uploaded.
• Standard, Drop D, Open G and ukulele
• The deviation in cents, with the string number beside the note
• Reference tones: tap a string to hear its pitch
• It says "not enough signal" instead of guessing a string
• English, Russian and Polish
