This application has a great design, beautiful interface, and a wonderful idea behind it. I like that i has a tuner, then a fine tuner. However, I play the flute, and this application can only tune my low register. for anyone who knows anything about flute, you would know that about 40% of my playing is actually done there, maybe less. Therefor, it is limited. Furthermore, it is completely useless when attempting to tune a piccolo. Once the pitch gets high enough, the tuner just starts jumping all over the place, and never hitting what the pitch actually is.

with the pitchpipe update its even better this is the best tuner hands down and is 4 dollar and the others are 10, I tested it on my keyboard which has perfect tuning and it was dead accurate- I love this

I'm a professional musician (guitar, piano, voice & trombone) and I have loved this app since the first version. I never understood the bad reviews, the wheel doesn't spin wildly if you sustain your pitch. It only spins if there is no pitch, which is normal. It tunes my acoustic guitar wonderfully and like I said, version 1.0 was great. BUT the latest update has blown me away! Literally, there are now over a dozen choices of temperament! It's amazing. Even my $80 Boss tuner doesn't have that feature!!! This is a pro app in my opinion, and I use it before every gig.

This is a great tuner except for one thing. I have a six string fretless bass, and this tuner will even tune my low "B". That's something that only pretty expensive tuners will accomplish. However, it often recognizes my "A" as an "E". That's something that inexpensive tuners never do. I'll say this, it's great to be able to tune one string with my iPhone and then the rest by ear quickly. Simple app - and that's good. (Please fix that one problem...) Thanks!

I am a high school choir director, licensed to teach vocal, instrumental (band, orchestra), and general music. I am an accomplished tenor and tuba player, and I hold a master's degree (M.A.) and doctorate (Ph.D.) in music education. I have purchased and tried two tuners from the App Store. I only chose those two applications because they were intended to tune all instruments, not just a specific instrument (e.g. guitar). The first version of this application was excellent. The tuner was less "twitchy" than the competition, and it looked visually better. As a choral director, the tone generator had potential as a pitch pipe (and the current pitch pipe options on the App Store are flawed). I took the time to e-mail comments to the creator of this application, and the creator took the time to respond to my feedback, and in the most current version, add the very features I was looking for. The only thing this application currently lacks as a complete tool for music education is the inclusion of a metronome. Otherwise, the tuner works very well, the ability to turn the pitch generator on and off makes that feature applicable for choral music education, and the author also included the ability to switch between tuning systems and display options (sharps, flats, and others), as well as systems used in other countries, transpositions, waveform, and more. In summary, this is a complete application, the author continues to make the product better and listens to suggestions, and this program is a good value, and it should never have to lower its price (check out the price of comparable stand-alone tuners). I would also like to add that I am not employed by the company that produces this application, nor do I know the author of the software. I am a music educator who uses this product, and I recommend it to you.

This app is very much like one of those small electronic tuners (e.g., the Korg); I had no trouble using it.

This is a great tuner, and works really well for tuning the french horn, which i play. It picks up the sound great even in a noisy band room, which is very useful. It is also a great price for a tuner and a pitch pipe in one app. One thing I would like to see is a play/pause button for the pitch pipe. When you select the pitch pipe there is no way of turning the speaker volume down or changing the pitch. So if there was a play button that would be great. Also, having the option to adjust the range of the finer tuner would be nice because it's a little sensitive for some purposes. But this isn't a big deal at all. Worth the price if you could use a tuner but just don't want to carry a dedicated one around. Overall, with the 1.1 update it deserves a 4.5 star rating.

Great updates! No complaints here.

I'm using this to tune a violin. It works OK for A and D, but G seems a bit low for it to lock on. My main problem is E. The tuner has no minimum sound threshold, and seems to settle on E when there is no sound except soft background noise. Since the violin sound decays rather quickly I don't know when the tuner is actually hearing the E rather than just showing its default background noise position.

I own others but this is the one I use the most. It's fast, simple, accurate and easy to use in stage type environments. Worth every dime!

Excellent app. I use it to tune while playing F Horn in orchestra and concert bands and it does a great job.

I bought this based on the design but unfortunately it's useless for tuning a guitar...the reading jumps all over the place, even in a completely quiet room.

This nifty little application turns your iPhone into a guitar tuner.... or an anything tuner for that matter.... worth every penny!

This app works just as described.

Definitely works well, a good buy

How do I get the other screens? All I have is the tone wheel (screen shot 1). I'm tapping all over the place, but can't get anything other than the wheel.

Hi Everybody! (hi Dr.Nick, simpsons humor) This is the first iPhone app I have actually paid for, and I have got to tell ya, it is worth hundreds of dollars! I was the top saleman in the nation for Musicians Friend a few years back and I have sold strobe tuners that cost over $5,000 and I must say this app tunes almost as well in my opinion. I just tuned my classical guitar and was very impressed! Then I tuned my 12 string in about a minute and WOW! I am excited to see how well it works on my daughters harp. Buy this app! I now have a High quality tuner with me everywhere I go, Thank you to the designers and keep up the great work!

I found myself at a rehearsal in need of a tuner, and I had neglected to bring my orchestral tuner that had set me back $130. A quick trip to the app store found me downloading Cleartune, expecting a merely acceptable temporary solution to my current predicament. I was completely blown away at the accuracy and sensitivity, however - this is superior to my orchestral tuner! Wonderfully smooth reaction to subtle pitch changes on the dial, plus the super-sensitive gauge on top, makes it incredibly easy, quick, and satisfying experience to tune. I don't worry about bringing my orchestral tuner any more - now I know I always have a superior tuner in my pocket.

All that happens is the meter spins and spins - in a silent room. Beware. It just doesn't work. I'd like my $3.99 back (sigh).

I'm hoping that mine is an isolated case, as it seems like this app should be great, but the wheel spins constantly, as though the mic is picking up hundreds of different pitches, often fails to register the correct pitch (off by a 5th-or 4th, depending on which way 'round you go), and the new update fails to install on my iPhone. I was really waiting for a chromatic tuner for iPhone, and everyone seemed to say that this was it... hopefully someone can help...

I purchased this app to touch up my 9' Baldwin Concert Grand. It doesn't work in the two highest octaves. It was worth the $3.99 to find out. It works great in the middle range but then I have to tune by ear the rest of the way, which is extremely difficult.

Umm... I aim the iPhone mic at the sound hole of the guitar just inches away. This tuner will not stabilize on a note ever, bouncing every which way. Trying other tuner applications with the iPhone in the exact same position which worked great. Sorry not worth the price of admission until this is fixed! I'm disappointed cause it looked so good. Unfortunately a great GUI can't change an inoperable application. So Matt got an update yet?

I would still recomennd the old fasioned tuners that you buy at a store.

The previous update routed the audio through the earpiece. The current update has fixed that.

Actually replaces a $25 or $30 tuner! Works great with my trumpet!

I have tried other chromatic tuners for I-Phone and this is the best of the bunch. The only problem I have is that lower in the range it seems to pick up on an overtone.

This app kicks butts. So accurate(I tried it on my keyboard and WOW). Also great for other uses. Highly RECOMMENED.

I inherited an old upright piano and wanted tune it myself. When I started pricing chromatic tuners and saw how expensive they were, I thought I'd try the App Store. I found Cleartune, and it worked just fine. Saved me $50! A very worthwhile investment...

Thanks, Matt!

1. Ramp the volume up and down when switching the pitch pipe on or off so we don't hear the attack transient.

I can't believe how good this app works. The tuning really is very accurate. And it's only $4. If you consider that a regular guitar tuner will run you $14 on the cheap end, and upwards to $40, this really is great deal. It's very simple, accurate, and fits in my pocket.

I've been playing guitar for 45 years. I started out with pitch pipe type tuners. Electronics weren't invented yet. I've tried 30-40 different types. With most of them, I need to tweak the tuning to my ear to get it right after using the electronics. With this tuner, I can tune and play. It's dead on every time. If I were in a noisy room, however, I still might need to plug in my Boss guitar/tuner using the standard guitar cable, but in home situations where ambient noise isn't a problem, this application is superior to any tuner I've used. By this way, this is my first and only app review. I feel that strongly about this tuner!

I had to add yet another 5 star review for this app to go with all the others. Picks up sound great and works perfectly. If you have any instuments this is a must buy!

This was used to tune an orchestra for a professional performance. It was cool to see the concertmaster tuning a real orchestra with an iphone! I trust it very much.
