Quick Summary : Multi-strobed strobe tuner ideal for tuning instruments with many harmonics (steel pan etc), or for use by sound engineers and professionals.


A Strobe Tuner for the iPhone. Use this to tune your instruments. The strobe tuner will convert the sound signals into light signals on a virtual strobe that turns at the frequency of a particular note.

The strobe tuner has a very fast response rate, as it does not use complicated processing in order to estimate your tone. Rather, it visualizes the sound input relative to the inner frequency.


-> Automatic Recognition: Recognizes which note you are playing and adjusts the strobe frequency to that tone.

-> Triple Strobe (unique!): This strobe tuner displays three strobe notes at once: useful for identifying the harmonics of your instrument.

-> Tone wheel: A simple tone wheel visualizes the different harmonics of the tone that you play.

-> Timbre Visualization: Tap the screen once to activate the timbre visualization. You can see what your voice "looks" like when decomposed into different notes.

-> Chord Triad Visualization (experimental): Visualizes the sounds in a triad space.

-> Change A4 Frequency: Using 435hz instead of 440hz for the A pitch? No problem, just specify A440 in the settings pad.

-> Calibration: Do you have access to a supremely accurate sound generator? You can calibrate the device's internal frequency as well (to numbers other than 44100hz).

The accuracy of the strobe tuner is only limited by the device's internal frequency generator, which is very accurate. If you want, you can calibrate it against an extremely accurate signal generator. Tuning forks are not acceptable.

Excellent for price, only minor flaws

I use this on my iPod Touch 4 with the built-in mic. The accuracy and visualization are great. That's what matters most to me and makes it worth more than its price. I use "Oldmode Manual" because of two minor flaws: First, the auto pitch recognition is not as good as other software strobe tuners. Second, on "Promode" manual mode, it's difficult to change the reference pitch to different notes without accidentally adjusting the exact frequency (i.e., other than A440). Also, it offers only equal temperament, worth noting if you're used to tuners with other temperaments.

The Best

I play the harp and just had it regulated by a professional. I was told that this application is the best for tuning. I have a few different chromatic tuners that I use but I never thought that a recommendation from a person who fine tunes harps for a living would direct me to a iPhone app.

2/5 stars

Looks very cool, but has very poor pitch recognition

I'm torn about rating this app. On one hand, it looks absolutely awesome, and it has some very interesting features. On the other hand, it falters in the basics, like pitch recognition. I'm a professional musician and have used a number of software strobe tuners in the past. When tuning my cello, none have had difficulty in identifying the pitches of the open strings. The primary frequency is very clear. Yet this app is consistently confused about what note it is getting. The A string works, but both the D and C strings are always misidentified as 'G'. Something isn't working right with the pitch recognition.

If this is fixed, I'd happily give the app 5 stars, but for now it's rather frustrating. Yes, there's manual mode, but that really shouldn't be necessary to use and it's a hassle.

Two more suggestions while i'm at it: the display is rather dark. In a brightly lit room it can be a bit hard to see. And a landscape mode would be useful. When it's placed upright on a music stand, the mic (at the bottom) is blocked, so i'd prefer to use it sideways, but of course then the display is rotated 90 degrees...
