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.

Strobe tuner fans --- this is YOUR Valhalla!

If you've got the patience and know what you're doing and need professional accuracy--- and perhaps a little eye candy, to boot--- you've found your tuner. This thing is better than the peter*** strobe for the ip(2), and at least as accurate.

That said, if all you want is a quickie "boss style" needle tuner and don't care how accurate ur pitches are, then this probably won't be to ur liking.

Oh, and did I say---- it's FREE????

Ty to the developers. My only beef is that I was not aware that I'd have to pay an extra $1 for color. It's a small price to pay but I felt just a bit of a "bait and switch" happening...

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!
