The challenge

What Fit in 7 needed to solve.

Fit in 7 wanted people who never find a free hour to still get a real workout done. The product had to fit a complete circuit into seven minutes, guide every move and rest with clear cues, and bring members back day after day across both iOS and Android.

Goals

Fit a complete circuit into a seven minute session
Guide each move with clear visual and audio cues
Make starting a workout a single tap
Hold one consistent experience across iOS and Android
Keep members coming back with streaks and progress

The solution

Resourcifi built Fit in 7 as a native app on both platforms, with a dark, focused interface built around the seven minute format. A featured session sits on the home screen, a guided player runs the timer for each move, and a progress view rolls up streaks, minutes, and Apple Health data in one place.

What we built
