This metronome (10 to 250 BPM) includes a tuner; you can set the tempo, rhythm and notes per measure from 1 to 9. The tuner emits reference pitches for any of the 12 notes in an octave from A to G#.
Simple, efficient combination app. Selectable metronome rhythms (quarter note, eighth note, triplet, etc). 
No tap tempo or visual feedback for the metronome. Doesn’t detect pitch from the mic.
