The record

Purpose: Fine Tuner listens to an instrument through the device’s audio input, detects notes in real time, and shows whether they are in tune, too high, or too low.
Instrument coverage: The app includes instrument families such as guitars, basses, violins, ukuleles, banjos, and mandolins, with standard and alternative tunings.
Tuning modes: It offers automatic note detection, manual target-note selection, and chromatic mode for tuning any note.
Displays: The tuner provides a needle dial, a graph of pitch over time, and a spectrum showing the fundamental frequency and harmonics.
Ear training: The Circle of Notes plays reference notes and chords to support tuning by ear and pitch practice.
Customization: Settings include reference frequency, temperament, detection sensitivity, microphone gain, note-name notation, and sharp or flat display.
Custom tunings: Users can create custom tunings with 1 to 99 notes, each defined by a frequency from 20 to 5000 Hz.
Free-version limits: On mobile, spectrum use is free for about two minutes per 24-hour period, and creating and saving custom tunings requires the full version.
Audio inputs: The app can use the built-in microphone, a USB audio interface, or line-in when the operating system exposes those inputs.
External hardware guidance: For directly connecting an electric instrument, the guide recommends an audio interface with an instrument input for more reliable detection than microphone pickup.
Mobile platform availability: The maker lists Android and iOS as available platforms.
Desktop platform availability: The maker lists Windows as an available platform.
Support: The user guide directs users with questions to contact the maker by email.
Maker background: UrionSoft says it has worked on application development for over 25 years.
