Ultra-accurate - Ultra-fast - Ultra-responsive

Looking for the most accurate instrument and calibration tuner for Android? Congratulations, you've just found it. UltraTuner is the most precise digital tuner available for Android, providing accurate readings down to .01 (yes, that’s 1/100th) of a cent. UltraTuner is 10x more precise than mechanical strobe tuners, which are considered the "gold standard" when it comes to precision tuning — and they don't typically fit in your shirt pocket! With UltraTuner, you have a standalone app for your Android device that lets you tune with extreme accuracy everywhere you go.



A patented engine with 10 times more accuracy

UltraTuner’s precise pitch detection is achieved through a proprietary dual-analysis processing engine. This allows the tuner to get a much more accurate reading of the frequency from the incoming note. UltraTuner gives you accuracy down to +/- 1/100th of a cent, that's 10 times more accurate than a mechanical strobe tuner. So now, when you tune your instrument, you can rest assured that your notes are right on the money. UltraTuner is the perfect companion for guitar technicians who need to ensure that their instruments are intonated correctly and in-tune from the first fret to the last.

With its ultra-precise note detection engine, UltraTuner is also perfect for calibrating instruments like keyboards and vintage synthesizers. It lets you easily restore their intonation to a perfect playing pitch. UltraTuner gives you the confidence to know that you're going to be in tune, every time.

Super fast

One of the joys of owning a precision tuning app is how quickly it responds. It gives you precise pitch accuracy with a speed that displays before note's transient attack has leveled — it's almost faster than your eye can detect. Now that’s fast!



High visibility

Designed to be used on stage and in the studio, UltraTuner features an intuitive and visible GUI that's easy to see in both low and bright light conditions. Just strike a note, and no matter where you are, you'll be able to clearly see whether it's flat, sharp or right on target.

Made for the stage. Made for the studio.

UltraTuner allows you to switch between two operational modes: Stage and Studio. These modes let you choose the visual readout and type of tuning information displayed. You can go from simple to complex at the touch of a button, depending on your needs.


Stage mode - high visibility


Studio mode - pitch over time display


Studio mode - waveform display

Stage mode

When in Stage mode, UltraTuner is streamlined to work as a straightforward, ultra-accurate tuner. Its simple interface makes it easy to read tuning information in both low and high-intensity lighting situations. This is made possible by its bright, LED-like bars that light yellow to indicate degrees from pitch and light green when the note is in tune. And because UltraTuner utilizes your device's entire screen, it's easily visible from a distance on any stage.


Studio mode

UltraTuner is versatile. It lets you effortlessly switch between a standard tuning environment and one that displays the full breadth of its proprietary pitch time tracking. Studio mode allows you to monitor and track the accuracy of the pitch of a note over time, in real time. This is extremely useful for vocal and ear training purposes and also for musicians who play non-chromatic instruments like violin, fretlass bass, brass instruments, woodwinds and more.

Studio mode offers two different visualizations of pitch: pitch over time and a proprietary oscilloscope waveform display. The oscilloscope display provides an animated waveform that stays till when on pitch and moves left or right when flat or sharp. This visualization is perfectly suited for vocal training and non-chromatic instrument pitch monitoring.

Quick calibration

In the settings window, you can quickly and easily calibrate the “A” note so you can play with anyone. You can also change the temperament type (a professional feature not found in most tuners), and adjust the audio input sensitivity. Temperament selection includes: Equal, Pythagorean, Just Major, 1/4 Comma Mean Tone, Kimberger III, Werckmeister III, Young and Kellner. UltraTuner works with the built-in mic input for acoustic instruments, and works with all analog or digital audio interfaces for Android devices like IK’s iRig 2, iRig HD-A and the iRig Mic series of products.
