In order to build value, and to deliver it fast, I had to rely on my experience, with a strong background in Product Design, it was clear for me that this gave me a solid advantage. My vision was to create a seamless user experience, which helped users to focus on their workouts rather than learning how to use the tool. I wanted to create an “invisible interface”. I know what you are thinking, “invisible” would mean that users won’t see it, and perhaps you might think of voice commands or the Apple Watch’s Double Tap… But no, even though I’m keen to explore those, for now I was good with “background interface”, and again you might think that I’m not coming to the point, but I have to insist, because it is important, I really want you to catch the idea. After doing a few experiments, training by myself while logging in my workouts in my notepads, whiteboard and Google Calendar, I found that I needed a workout tool that wouldn't feel intrusive. It had to be like it's not even there, quietly guiding me in the background (see what I meant by “background interface”, “invisible interface”, etc.). This tool would tell me what to do, especially the first few times, as in my experience I have seen that once you get the technique, the rest is practice. So, I gradually understood that during my workouts, between sets and sets, my ideal interaction could come in the form of a tap, but not just any tap; I didn’t want to think on which exercise to tap or to find the one I was doing. I wanted a seamless experience where one tap would guide me through my current set and automatically transition to the instructions of my next set or exercise, if this was the last set in a series.
