What insTuner is

insTuner is a chromatic tuner for instruments ranging from guitars and pianos to bowed strings, brass, woodwinds and drums. Its five tuning modes are Instant Tuning, Fine-Tuning, Strobe Tuning, Spectrum (FFT) and Spectrogram. A note wheel shows the detected note, with the octave beneath the dial; Fine-Tuning adds cent deviation and frequency. Spectrum mode analyzes frequencies and lets users switch its X-axis between logarithmic and linear scales. A built-in tone generator offers four waveforms for tuning by ear. The free edition includes Instant-Tuning Mode and the tone generator. The Mac app adds fine-tuning, historical curve tuning and tuning settings, including Concert A frequency, temperament and input source. The listed Mac compatibility is macOS 10.9 or later. The maker says its paid app can be bought once for use on iPhone, iPad and iPod Touch. The maker lists its founding year as 2012 and locations in Hangzhou, China and Berlin, Germany.
