Sad to see J&J retire this app
This app has been with me for the last 7 years plus and made me love HIIT. I loved it’s simple, clutter-free interface. It allowed me to customise my exercises to keep the ones I liked and drop the ones I did not like. This one feature gave me a sense of control over what I did and made me enjoy my exercise routine. It also helped me go from one cycle of exercises to three - that helped me adapt to the rigour of the routine and stay motivated. And surprisingly this app was absolutely free! J&J has given no reason for retiring this great app. I hope they re-introduce it at some time.
