About this app
Trace Tuner is a simple but accurate chromatic tuner. In contrast to similar apps, you will not get the look and feel of a hardware tuner with a slow and damped needle. Instead, you will see the trace of your tuning over the last five seconds. By this, the reaction of the tuner can be faster and more accurate, but still gives you the feeling for your tuning. To keep it simple, only the neccessary features are implemented: ● Frequency spectrum to check your input ● The concert pitch of 440Hz can be variied in 1Hz steps ● Choose your favorite notation (English, German, Solfège) ● Support for transposing instruments The tuner works with the build in microphone of the iPhone. For the iPod touch you will need an external microphone.
