An excellent workflow tool

While there are many apps and programs available to do this kind of calculations, there are none that I am aware of which combine so many great studio workflow enhancement tools together in on handy package. I suspect this will become an invaluable bit of kit in the studio and live. A brilliant bit of design by an excellent team. Cheers!

Great app

I’ve had it in the past on previous devices. It comes in handy more than I thought.
But the numeric input is not functional in this version on my iPhone X.
