Optima Guitar Tuner v3.0

Many years ago I created my first iPhone app called Optima Guitar Tuner for a company I worked at called Optima Design Services Ltd.  Years later they asked if I would like to take the project back via App Transfer and update it for all their users as it no longer worked on iOS 11.   Optima are a great company and have supported me over the years so, yes.  I took this on.

Over the last couple of days I have stripped out all the advertising, updated the app to use the latest 64 bit SDK and worked around all the depreciated methods that Apple no longer want anybody to use.  The app is now in submission to Apple so hopefully will be available in the next couple of days.

As for future updates, let me know what you want.
