DaTuner vs Fender Tune

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.
