Peterson Strobe
What Peterson Strobe is
Peterson Strobe is a paid strobe tuner app for Android devices. It tunes through a built-in microphone or external audio interface and specifies accuracy of 0.1 cents. The note range extends from Eb0 to Eb8, or MIDI notes 15 through 111. Concert A can be calibrated from 340 Hz to 540 Hz, with 440 Hz set by default. Notes may be selected automatically or manually, and transposition covers −12 to +12 semitones in one-semitone steps. The app includes four Sweetened Tunings for guitar and bass and 11 Historic Temperaments. It supports alternate tunings, custom reference pitch, offline use, and a strobe display. Presets are factory configured, so users cannot create or save their own. The Android version has no metronome, tone generator, or Peterson Connect compatibility. Peterson lists compatibility with iRig, iRig2, and Apogee Jam devices. The app costs $9.99, paid once.
