Movement in context
See how stroke patterns, turns, and underwaters connect to the length being swum.

to Every Length.
A stopwatch records the result. A coach needs to understand the swimming behind it.
The Gap
What Coaches See vs. What They Miss
From the deck
The touch. The time. The visible stroke.
A coach can time a finish and watch a swimmer’s form. But tracking every turn, underwater, and technical change across an entire lane is much harder.

Why I’m building HydroVision
It started at practice.
I’m Benjamin Mitchell, a competitive swimmer, coach, and Mechanical Engineering student at USF. Coaching multiple lanes at once means you’re constantly trying to watch everything at the same time, and that just isn’t possible. You can see when a swimmer starts to fall off, but understanding exactly what changed in their stroke can be much harder.
That’s what I’m building HydroVision to solve. The goal is to give coaches a clearer view of what’s happening in the water, in real time, so they can make more specific adjustments while the swimmer is still in the set. If someone’s body position starts breaking down, their rotation changes, or their timing drifts as they fatigue, I want that information to be visible when it can actually be acted on.
HydroVision is still being built and tested, and that matters to me. I’m designing it around something I would actually want to use on deck: comfortable for the swimmer, simple for the coach, and useful for understanding more than just time and splits.
HydroVision is in active development and pool testing. We’re looking for coaches, teams and partners who want to help shape the product.
