For the last year, I tuned my fiddle with an iPhone app. I started using this device for tuning one week ago. It is very easy to use. Just turn it on, make sure it is set to the appropriate instrument (it usually remains on the violin for me) and pluck the strings one at the time. When I am in a noisy environment, I plug in the sensor and clip it onto the bridge. Then I can tune in the noisiest conditions and get accurate tuning even in a room full of active instruments.
When using the iPhone, I find it difficult to tune with any other noise, even from outside. It is also difficult to get an accurate reading on the "G" string even when it is quiet.
Without the sensor plugged in, the Rowin works in environments where the noise renders the iPhone app useless and it reads the "G" string as easily as any other. With the sensor plugged in, I can even tune my silent violin right next to someone playing or tuning an acoustic violin without it being interfered with.
It also has a chromatic scale so I can see how accurately I play non-open string notes. This is important to me as I am a beginner.
Additionally, this device has a metronome and a tone generator. I haven't used these features but I plan to incorporate the metronome into my practice after my next lesson.
Finally, I experimented with the sensor cord and found that I can plug it into an electric guitar amp and add sound effects to my fiddle. With an adapter, I can plug it into my computer and record playing a piece of music. However, the sensor acts somewhat like a microphone and picks up voice and other noises in the amp or recording mode so it won't substitute for a dedicated pickup.
