Professional musicians prefer strobe tuners for tuning speed and accuracy. The HotPaw inTuna Strobe Guitar Tuner allows you to quickly and accurately tune your guitar via unique, responsive, and high contrast visual displays. Optional multi-stobe tuning mode for simultaneous display of a strobe for each string... fast and accurate even in noisy environments.

The inTuna guitar tuner includes both a large frequency meter and a precise pitch strobe window. You can let inTuna auto-select the guitar string being tuned, or touch the Lock icon to lock tuning to a selected string. A 6 string tuning indicator indicates the string which has been selected for pitch measurement. Above the tuning indicator is a unique waterfall waveform display within a Strobe window to assist with accurate fine tuning. Configuration options include support for 8 popular guitar tunings and a Concert-A440 frequency adjustment.

Also, please take a look in the iOS App store for HotPaw Sing-inTuna, a "vocal tuner", and Music Spectrograph for sound visualization and music transcription.

Needs Some Work

Tuning a guitar isn't easy in my opinion and this application doesn't help. I have attempted to tune mine and the app continues to freeze on me. It jumps around from string to string and doesn't allow me, as far as I am concerned, to pick which string I am tuning within the app. If it was improved, I would greatly appreciate it.

Great App

I was cleaning up my apartment today, when I all of a sudden had an itch to play my guitar which had been lying in a corner for about a year. I cleaned it and re-strung it, and then realized I had no tuner. (The last tuner I had was a windows app called guitar tuner, on a computer I hadn't booted in years). So, I decided to download an iPhone tuner app. I first downloaded another tuner app before getting this one, and couldn't figure how the heck to use it. Then, I got this one, and within about a minute, I had my guitar perfectly tuned. The interface is very simple and intuitive, and there are alternate guitar tunings available, although, I probably won't be using those any time soon. The only comment I have to the developer is that they should make the app force the iPhone into an always on state, as currently, the iPhone screen dims every 20 seconds, requiring a tap on the screen to un-dim. Otherwise, a great app well worth a few bucks. Thank you!

Great app for anyone used to a strobe tuner

This is a very accurate tuner. I don’t really use the course tuner part as much as the strobe at the top. I own a Peterson Strobe tuner and have checked the accuracy of this application against my Peterson and was very impressed. It does have problems in high noise areas, but all tuners do. I manually select the string if it’s having problems. BTW Peterson Strobe $135 so $5 is well worth it.
