great app, clean and simple for intervall training.
would be great, if possible to rename phases and have personal sounds.

Currently phases don’t have names. Could you explain your use case for naming them?
Personal sounds is a feature I’d also like to implement.

By giving the phases different names, it is possible to separate exercise intervals—for example, push-ups, sit-ups, etc.
