Smiley Tuner - Accurate tuning

Smiley Tuner lets you tune guitar, bass, and ukulele with sensitivity as precise as 0.01 Hz in a silent room. Match the indexes to the center within the green area to be in tune. It offers more than 50 tuning types (guitar: drop, open, etc.), 9 ukulele tunings (including tenor and baritone), 8 bass tunings, 6 banjo tunings, and 7 mandolin tunings, with auto and manual string selection and octave/tone approach indexes.

An integrated phoneAmp amplifier with studio effects and a recording feature, plus a metronome with beat grouping, rounds out the toolkit. All features are available with a one-time payment for lifetime access—no subscriptions or auto-renewals.
