TrueMetronome is the only app worthy of being called a metronome. Almost all metronome apps boast about their accuracy, but users with sensitive hearing notice inaccurate beats all the time. Despite the failure of other apps, perfect time is possible for TrueMetronome: its unique engine creates perfect beats with ABSOLUTE ZERO error. For this reason, TrueMetronome is most accurate metronome app.
Sound quality is the second issue for software metronomes. Serious musicians prefer a natural sound filled with overtones, but all metronome apps play synthetic samples. Thus, you hear an artificial, dead sound. Moreover, the identical samples playing at the same frequency can drive any man crazy! TrueMetronome solves this problem thoroughly: all sounds are recorded from real metronomes and each beat's sound is a little different from the others. All this contributes to the natural sound which is easier on your ears.
Finally, an aesthetic, thoughtful interface is an important aspect of any application, and TrueMetronome pays particular attention to it. Creating an electronic metronome interface is simple, but TrueMetronome does not cut corners: it recreates the look and feel of a real mechanical metronome; every mark on the scale is labeled with a tempo mark, the deviation angle of the pendulum depends on the tempo, and the tempo is selected by dragging the weight.
