iPhone Giveaway of the Day - TimperTuner Pro

TimperTuner is a full-range accurate and easy to use chromatic tuner that gives clear feedback with a visual design that makes maximum use of the screen. A consistent horizontal display for fine and coarse tuning allows easy tracking of the needle as a note is played. The display is suitable for both tuning and intonation practice. A quick tune mode provides fast confirmation in live situations. Three color schemes allow one to choose from a white, warm, or dark background for comfortable viewing. Tone generation is also supported for droning.

An advanced digital algorithm is used to allow precise tuning of all instruments (strings, woodwinds, brass, plucked string, etc). Many tuners have difficulty with low registers (such as bass and bassoon) or those with many overtones but TimperTuner employs algorithms specifically aware of harmonic distributions. By taking advantage of the real-time behavior of multiple waveforms, vibrato can be detected and is shown as a highlighted region around the needle.
