APTuner is a sophisticated chromatic tuner for your computer, tablet, and phone.
Come see the unparalleled accuracy and insightful user interface features.
APTuner is built around a best-in-class note detector spanning 8 octaves even for low piano notes.
Our analysis algorithm eliminates many of the octave or fifth errors you often see with other tuners.
New to version 1.2 is our true 8 octave strobe display. Every audio sample is fed through the GPU to calculate the real stroboscopic effect--exactly like a mechanical spinning disk. Looks absolutely amazing in landscape on a retina display! (currently only for iPhone) More Info »
For the aspiring musicians in the group, you will love APTuner's exclusive Performance Analyzer feature. Get an in-depth analysis of your playing ability over time. This is perfect for ear-training, scales, and getting a better awareness of your tonal quality.
You can also watch the loudness of each note against its pitch. This way you are not only improving the consistency of your tone, but your volume as well. (currently only for iPhone)
