I have had created an application called Chromatic Tuner which helps you to tune your instrument. However when I put the application on sale; I received some feedback that it was not very responsive. In fact I knew that however I had no time to improve it. See it in youtube.
Now I am offering it as free on Bada market (since customers are not happy) and I put all the code on github. If you are a new developer on Samsung Bada platform it may help you. Meanwhile it is the only application I have done for Bada; so note that I am not an expert in Bada platform:).
Github address is: https://github.com/yamanyar/Tuner-for-Samsung-Bada
