Awesome App!

Im a personal trainer and I use this app almost every day. HIIT has never been easier to maintain for my clients. Being able to adjust the time of each interval, the rest periods and the music in the background allows me to focus on the client rather than watching my stop watch or clock. It keeps individual sessions on track and on time! I highly recommend the Pro version so you can save your setups. It saves time which keeps you focus on training instead of App configuration.
