Won't work on SE – Bangers - Make music, beats & remix the DJ hits Review

I have an iPhone SE that's ISO 10.1.1 and once I open the app and tells me to choose a type of genre of music I would like to use it freezes. I have waited up to 20 mins and it wouldn't work, please help. Sincerely iPhone SE user
