Is Tuning fork safe?

This simple application is intended first of all for those musicians who like to tune their instruments relying mainly on ears rather than using various modern tuners with visual indication, or for all who needs a reference musical tone for any reason. It produces an audible reference tone by demand just like a classic tuning fork, and, being installed on a smartphone, is always ready to use.
