insTuner is a chromatic tuner that helps you tune instruments quickly and accurately. It also features a Tone Generator just like a pitch pipe with four different wave forms.

With advanced DSP (Digital Signal Processing) algorithm, it is highly accurate (±1/1000 semitone or ±0.1 cent precision). Rather than providing only one mode like other tuners, insTuner supports different tuning modes applicable to different situations, such as Instant Tuning Mode for quick tune and play, Fine and Strobe Modes for accurate tuning, FFT Mode for sound analysis etc. What's more, many advanced features are provided such as Concert A calibration, historical temperaments and transpositions, which make it more powerful than other tuners.

insTuner is well-designed and easy to use. It features a unique "fixed" note wheel, which helps you to find the position of detected pitch easily. You can also use it as an electronic pitch pipe to tune by ear, matching the generated tones.

It is suitable for tuning acoustic or electric guitar and bass, ukulele, mandolin, banjo, bouzouki, bowed strings, woodwinds, brass, timpani and more. In fact, almost any instrument that sustains a tone can be tuned using insTuner. It supports Built-in Microphone as well as Line-in and other audio interface such as Apogee One. Clip Microphone is supported too.

"Best tuner I've ever had. I'm a professional clarinetist, and I've told all of my musician friends to use this app."

"I highly recommend this app and who can beat the price. My violin teacher compared it to her personal device. She wants an ipad to get the app for her personal use. "

"I have the iPhone 5 and play tenor sax, I compared this to a 40 dollar tuner and its perfect..."

"As a high school band director, I use this tuner more often than my strobo tuner. Besides the obvious portability, it is actually a bit more sensitive than the multi thousand dollar strobo and I Iove the multitude of options!"

"Absolutely love this app. I use it for my guitar, my son's violin and upright bass. The new features are even more amazing..."
