Run it in Guided Access

love the app & use it with Riff Station, which give me the chords from any song & transpose it to what Polychord can handle.
While strumming Polychord, you can accidentally shrink & close it, … so I lock the app down by running it with IPad Guided Access.
Thanks sooo much for a great running app. My wish is to be able to select the individual chords to place on the palette.

Please Update!!!

Loved this app for a minute until it stopped getting updated.
Really wish the Devs would make it work again; and if that ever happens I’m crossing my fingers that it’s with AUv3.
