Spin Tuner

By Dave Hayden

Open iTunes to buy and download apps.

Description

Spin Tuner is a simple but powerful tuner, ideal for stringed instruments. Select a preset instrument or create your own—for each note in the tuning, Spin Tuner sums the microphone input against the reference signal and shows you the relative phase and amplitude. Or in plain English: When the spinner stops spinning, you're in tune.

I made this because I was disappointed there weren't any good free tuners in the App Store. If you like it and feel an overwhelming urge to pay something for it, I've added a fancy color mode as an In-App Purchase. IT'S LIKE A DISCO IN YOUR PANTS!

Enjoy!

Free version is pretty cool ... works with iOS 5.0.1 on an iPod Touch 4th gen

The free version is a way cool app ... I was able to add a viola in just a few minutes. It appears to rotate clockwise if you are too sharp, counter clockwise for flat, and a stable line when it's right. As each string is "plucked" or "played" the corresponding circle responds. It's not a "natural" for tuning an instrument after a string replacement but I can see it being great for a "quick check" when you unpack your instrument and set up to play it. If it's too far off you can use a chromatic tuner or pitch pipe to get it "close" and "finish" with this one as others here have done.
The big "down side" is that the color version is an "in app" purchase and it's not clear that the color version has any better documentation than the black and white one.

Awesome Tuner!

I was never able to tune my ukulele properly because I don't have an ear for the right tunes. But this app definitely made a difference. A bit confusing to understand at first, but it really helped me to tune my ukulele. It's probably the first time it has been properly tuned! Thank you so much! :D
Now the songs I play actually sound like they are supposed too!

I would definitely recommend this to anyone who needs help tuning!

Great Free Tuner for Any Musician

I play a variety of instruments, and have to tune a hundred times over to get the right tune. It's great that I can just pull out my phone or iPad and just play. The only downside is that you need to know the note names if you are adding an instrument, but it's not too hard to just look it up online when you get the chance. I highly recommend it, as it is a fun, great way to tune!
