DaTuner vs Intunator

DaTuner is an Android chromatic tuner and metronome for tuning instruments, including guitar, bass, violin, ukulele, banjo, cello, piano, and mandolin. It works offline and is designed for noisy environments. Auto-sensitivity can start tuning without manual setup, and users can adjust sensitivity themselves. The display turns green when a pitch is within the optimal tuning range. Screen lock can hold a chosen note, while filter lock isolates a particular note range. Reference frequency can be adjusted manually or set with an external reference for orchestra tuning; the stated sample-rate range is 8kHz to 48kHz. The PRO version adds a strobe display with up to four overtones, transposition, custom temperaments, notation options, a harmonic pitch pipe, and an enhanced tuning algorithm. Google Play says the app may collect and share app information, performance data, and device or other IDs, and that data cannot be deleted. The privacy policy says microphone audio is processed on-device and not stored on company servers.

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.
