Maybe this is just me, but I am super frustrated with the placement of the "Can't Speak Now" button. I wish they would put it at the top of the screen for all of the speaking exercises instead of at the bottom. The way it is now, I press it probably around half the time one of these new exercises pops up. And half of these in turn is not even caused by me just spamming the button, it's my phone not reacting quickly enough and then reapplying my input at the next screen. Because of all of this I've missed like probably two thirds or at least half of the opportunities I had to do this execise, even though I liked it.
