A free strobe tuner (or stroboscopic tuner - see ) is a musical instrument tuner that works differently to other type of electronic tuners.

To use the strobe tuner, select the desired note and observe the pattern created when playing. Rotation indicates that the note is sharp (clockwise) or flat (anticlockwise). The faster the rotation, the more out-of-tune. This rotation is very precise and gives a much more accurate result when compared to ordinary electronic tuners. Each ring on the disc corresponds to a partial above the fundamental (the two inner rings are below the fundamental) and can be used to tune instruments with many partials.

Configuration options
* Note and octave selection
* A4 = 440Hz (adjustable in fractions of a Hz)
* Mask aperture size (to adjust the pattern clarity)
* Noise threshold (to block out background noise)
* Frequency Calibration (adjusts in 0.1c increments to a specific device or instrument)
* Auto-detect note

This strobe tuner is not like some others around that "emulate" a "strobe display". This tuner has an internal model of virtual wheels and flash lamps that actually perform the same process that a real strobe tuner would do.

This free app is ad supported, so internet access is required. An unlock key is available on the market to remove ads, enable colour picking, and enable selecting of temperament (e.g. Equal, Just, Kirnberger, Werckmeister, Young). The free version must also be installed. Get it at

    than the expensive Peterson app. Still not as feature rich as, say, gStrings, but probably the best strobe tuner app. No tuner app can change your mic and phone's high pass filter to magically hear low frequencies, but have to rely on harmonic overtones. A strobe tuner can make it easier to compensate manually, as you see the harmonics.

    I absolutely love this tuner! I use it all the time on several acoustic instruments, and is a great quick tune when my big peterson tuner isn't close handy. I recommend this! !!

    Very good tuner. My only gripe is the text display in the middle of the circle is TINY. I almost need a magnifying glass. If it weren't for that I'd give it 5 stars.

    Three things make this the best tuner app: Its very accurate, works well in noisy environments and can be used with any instrument. Whether you are tuning a guitar, bass or piano strobe tuner works very well.
