Does anyone use the app Onsong for gigs? It's what we currently use for the kids busking and I wanted to pick someones brain about some things if anyone has experience with it?

My Mum thinks I should do this Lady Gaga song for my upcoming concert. What do you think. This is my first time playing it so it needs some practice. https://youtu.be/G06tVvZmkZU?feature=shared
