G-Tuner Chromatic Guitar Tuner

Hi there,

I released my first Android application yesterday: G-Tuner.
It's a chromatic tuner that listens through the microphone and works out what note you're playing.
There are some screenshots here: G-Tuner for Android

When I started working on it there were no other chromatic tuners available (in the UK anyway).
A few other people have beaten me to it, but I hope there's room for a few of them.

Within an hour of publishing my application I had my first rating: 1 star. :(
Things have picked up a little since then, but I'm wondering what caused the initial bad reviews. Maybe they had a different model phone, and the application just doesn't work.

I've only been able to test it on my own G1. Although a friend of a friend has tried it out on a Hero, and it seems to work.

If this type of application is of interest to you, and you have some feedback I'd be most grateful. Does it work for you? Does it look bad? Is it obvious how it works?

Any feedback or suggestions would be most welcome.

Thanks.

Thanks for the feedback!

I'd love to give g-strings a try as it gets rave reviews.
From the description on the website it looks more advanced than my app. He has a more sophisticated way of determining the fundamental frequency.

It appeared in the UK market place briefly, and I tried to download it several times, but the download failed each time. Then it disappeared, and doesn't show up any more.

Try going to the market while connected to WiFi. I find that T-Mobile seem to hide one or two things if I log onto the Market through HSDPA. Don't know why. If I connect to my home WiFi I can see a lot more.
 
Thanks for the suggestion, but I've tried GPRS & WiFi with no luck.
Also, I'm with Orange, so I don't think it'll be a T-Mobile problem in this case.
I'll keep trying now and again in case it shows up.
 
gStrings shows up in the android Market as "Tuner - gStrings". You can get more info and see some screenshots at cohortor.org/gstrings.
 
Thanks for that.
It might be a coincidence, but gStrings started to appear in the Market for me after I upgraded to 1.6, so I managed to download it a few weeks ago.
It's a very nice app, and deserves all the rave reviews. I gave it one myself. :)

Well, we could not quite get it.

I do not understand why it has a start and stop button. Do I hit start/stop for each string, or just once ? If I hit start, IMHO it should stay lit until I hit stop, so it is quite confusing just trying to figure out how to use it.

Also it does not work. I had a buddy with a just-tuned guitar try it, and the first two (lower) strings were perfect. After that, the readings just made no sense at all. I already deleted it from my phone by the time I saw this thread.
 
Thanks for the feedback.

The start & stop buttons are there to start & stop it listening through the microphone.
It helps to save the battery, as the app does quite a lot of CPU intensive stuff while it's listening. I'm sorry to hear you found the buttons confusing.

Once you hit Start, it will carry on listening until you hit stop, or until you leave the application. You can then play any strings or notes that you like, and it'll work out the frequency, and tell you the closest note.

I'm sorry it didn't work for you.

The lower strings (the lowest notes - the thicker strings) were actually the hardest to deal with, due to sampling rates and harmonics. The higher notes are much more likely to work. Obviously all the strings worked for me, otherwise I wouldn't have released the application. Audio hardware does seem to vary across the phone models, and as I only have a G1, it's difficult to make sure it works for everyone.

Anyway, as you've uninstalled it, this reply is probably redundant. :-)
I can recommend gStrings if you're still looking for a tuner application.

I think if start (or even a little red dot) had stayed lit until I hit stop, that would have helped my confusion a bit. (like the record lite on a camera). And maybe label it "listen". :rolleyes:

We were in a noisy bar, so that may have had some impact but we were listening thru his amp. Perhaps it was not picking up the loudest sound, but everything it could hear? The higher (middle) strings were closer to voice frequencies. Just trying to give you user info.


Also, I had vRecorder installed and it sounded liek crap. So maybe the mic on the droid is not good, or gets overloaded. vRecorder also uninstalled because it scrwed with my outbound phone calls and killed my phone.

I would try it again if you change anything.
