The Violin Tuner and Metronome app is, unsuprisingly, an Android app that will help you tune your violin and help you keep your playing in time.
The app has an accurate pitch detection feature for tuning that will listen to the note as you play and, if it is identified as an open string on the violin, it will highlight the string on the violin graphic along with the peg used to tune it. If the note is sharp of flat it will advise whicn way to turn thepeg to get it back in tune. A pitch detection meter gives detailed information about the note being played, the frequency detected and how sharp or flat it is (measured as deviating from the closest detected note).
The metronome is designed to look, sound and interact like a classic metronome in a gourgeous wooden cabinate. You select the required beats per minute (BPM) by simply sliding the dial up and down the pendulum as you would with a real metronome. The BPM and the associated tempo (as used in classicial music notation) is displayed at the bottom. After pressing "START" the pendulum will swing to and fro at the selected tempo and an audible "tock" is sounded for each beat. Use the volume control on your device to adjust the volume.
The app is designed to run on an Android phone or tablet device.
The app is free
