insTuner vs Intunator

insTuner is a chromatic tuner for instruments including guitar, bass, piano, bowed strings, brass, woodwinds and drums. It offers five modes: Instant Tuning, Fine-Tuning, Strobe Tuning, Spectrum (FFT) and Spectrogram. The note wheel identifies the note being heard and shows its octave beneath the dial. Fine-Tuning displays the note, cent deviation and frequency; Spectrum analyzes frequencies and allows a logarithmic or linear X-axis. A built-in tone generator produces four waveforms for tuning by ear. The free edition includes Instant-Tuning Mode and the tone generator. The paid plan is listed at $3.99 as a one-time purchase and includes the Mac app, fine-tuning, historical curve tuning, tone generation and tuning settings. Those settings include Concert A frequency, musical temperament and input source. The Mac listing requires macOS 10.9 or later. The maker says the paid app can be bought once for use on iPhone, iPad and iPod Touch. EUMLab says it was founded in 2012 and is based in Hangzhou, China and Berlin, Germany.

Intunator is an intonation-training app that recognizes a played note and plays back a corrected version for musicians to match by ear. It is designed for wind, string, and plucked-instrument players, as well as vocalists, and detects pitches across nearly seven octaves. Its display can show note names or solfege and graphically indicate pitch deviation. Settings include 56 instrument choices, transposition, concert pitch, background noise, note spelling, and pitch-detection options. Drone Mode provides a sustained chosen note for practice in equal or just temperament. Corrected notes can play through headphones or speakers, with fifth or octave offsets and three output sounds; turning off the control tone allows tuner use. Intunator is available for iOS and Android. The iOS INTUNATOR STARTUP version has a four-week free test, and TUNER PRO without the control tone has a two-week free test. Android renting and free testing are still in planning. Listed plans range from €2.99 a month for Tuner Pro to €49.99, paid once for Intonation Trainer Lifetime.
