Intervals Pro: HIIT Timer

I’ve been really disappointed in the past with other interval timers, sometimes needing 2 or even 3 different apps to do what I want/need. Intervals Pro: HIIT Timer gives me everything I want/need plus more. It is so easy to set up/customise and the level of detail when summarising your workout is amazing. As you can maybe tell, I would highly recommend 👍🏻
