It seems like a poor branding decision to name the app after the rather awkward domain name ("Hummi.nz"). As a mobile-first app, you aren't constrained by domain names, so you have better options.
Thanks for the feedback, this is definitely something I should consider. I guess I was inspired by musical.ly here. I also built and launched the app in a week and I didn't pay too much attention to the branding side of things
