Just what I need

As an inexpensive app, this is eyecatching, though I had to wrestle with which guitar et al. tuner on the app store because some look more stylish.
I made the choice to get this because it is a chromatic tuner, not ONLY a pitch pipe; also it is relatively the cheapest tuner that includes other instruments (personally used the ukelele tuner already, and may use the banjo tuner soon) alternate guitar tuning.
The program is very responsive and registers all notes exactly; I tested the tuner with my E tuning fork and it was perfect.
