Just one tap and you have an A. Clear, quick and easy.
Tune up. Play. Enjoy!
FEATURES
• Clear, authentic sound which fades out, just like a real tuning fork.
• The frequency is variable in the range 435-445 Hz.
• Change the frequency by tapping the sharp or flat symbol.
• A black toolbar indicates the frequency is at the default. By sharpening or flattening, the toolbar turns gray. A new default can then be set by double-tapping the number, whereas a single tap restores the fork to the default.
• Swipe left to access settings
• VoiceOver support
