Best Tuning and Metronome Apps for Playing and Teaching Music

Don't know where to start when browsing the app store for tuners and metronomes? There are so many choices, and you've probably noticed not all of them are great. I've narrowed it down for you. These are my top three favs -- hands down (and instruments up!). And nope, these are not promotions - I'm not getting paid to mention apps, or anything of the like. I'm simply sharing my little ole opinion in the hopes that it will help you.

Who is Queen Reed?
Queen Reed is just a name that sounded good to me once when I was signing up for something musicky and didn't want to provide my real name.  I am obviously not a queen. There is nothing I claim to rule, especially not reeds! And this rather presumptive title is at firm odds with the view I hold of myself as a performer, educator, creator, advocate, and occasionally (we've all been there), a complete imposter.

You, Me, We, have all had life and music experiences that help others when we share them. Along my way here, I have picked up a good deal about playing and teaching the barkystick we call the Clarinet. And when I zoom around the internet for help, advice, insight, I want the most specific, articulate help I can find. So this is what I offer - not only what works for me, but whenever I can figure it out, why and how I think it works. 
 
Quite simply, Queen Reed wants to share everything she knows about playing, learning, and teaching clarinet with the hope that it will make your life easier, help you feel connected to others, build your knowledge - which is power, and enable you to get more and more joy out of your own barkystick.
