The Best - World class

In my long time using tuners I NEVER had one that could match this tuner !
I use it both on iPad an iPhone - in any way it just works.
My experience with tuners goes back to 1965 using a metal tuning fork. Then in the early 1970 I got my first ELECTRONIC tuner, a very expensive tool, and actually with a mechanical scale very much similar to this iPad/iPhone version (yes incredible !!)
Then through the years I tries a lot of electronic tuner devises. Then one day I stumbled over a tuner in my App Store, and thought why not. And I tried many different tuners but all very not accurate and/or complicated to use. .....BUT THEN I found this one, and now I have it available on all my gadgets. Thank you for this tuner (does it have a name ??) ha ha
