Case Study · Product Design · 0→1 Experience
A unified workout experience built by a small team focused on clarity, connection, and real-time performance — turning a brand-new training flow into a routine athletes now rely on every day.
Tempus is BTWB’s boldest step forward — an end-to-end workout timing and tracking experience built directly into the core training workflow. Designed from the ground up, Tempus combines real-time performance insights with a dynamic social layer that keeps athletes motivated and connected.
As lead designer on this 0→1 initiative, I shaped the product vision, defined the multi-device experience, aligned stakeholders, and delivered a cohesive system now used daily by the fitness community.
This case study highlights how we turned a brand-new behavior — training with live data and shared leaderboards — into something athletes and gyms now treat as part of “how they work out.”
Led the end-to-end design of a new, real-time training experience across phone, watch, and in-gym displays — shaping a product that feels natural in the middle of hard workouts and is now part of athletes’ daily routines.
Unified timer, tracking, pacing, and live competition into a single, cohesive flow that supports solo sessions, live classes, and remote workouts.
Before Tempus, BTWB was great at tracking what happened after training: scores, PRs, and long-term progress. But the workout itself was supported by a patchwork of tools — phone timers, wall clocks, whiteboards, and chat groups.
We saw an opportunity to bring timing, tracking, and social motivation together into a single, connected experience — one that could work just as well in a noisy gym as it does at home.
Designing Tempus demanded more than UI work — it required a deep understanding of what athletes, coaches, and gyms are willing to interact with in the middle of hard workouts. I led the research effort, combining internal dogfooding with conversations across our community to shape what “real-time training” needed to feel like.
End User
"Once the clock starts, I can't babysit my phone. I just need to know my time, my pace, and if I’m ahead or behind."
Class Leader
"I want to see who’s working, who’s falling behind, and how hard the class is going — without leaving the floor."
Environment
"Anything we put on the floor has to be simple, durable, and readable at a glance. If it slows class down, it gets turned off."
Once the workout starts, interaction must be minimal — glanceable UI, not constant taps.
Data must be large, high contrast, and prioritized — time, pace, and key splits only.
"If I have to think about how to use it mid-workout, I’ll stop using it."
Coaches need to see who’s working, resting, or finished at a glance on a shared display.
"If we’re not in the same room, I still want it to feel like we’re doing the workout together."
Leaderboards, ghosts, and pacers should amplify coaching and community, not replace them.
This research anchored the Tempus roadmap: we focused first on making real-time training feel effortless for athletes, then layered on coaching visibility and shared experiences that make workouts feel more connected and intentional.
From concept to release, I acted as the Lead Product Designer for Tempus, owning the full design lifecycle across mobile, watch, and in-gym displays.
We didn’t launch Tempus as a single, monolithic feature. Instead, we shipped in three focused phases, validating each layer in real workouts before adding more complexity.
Start simple: give athletes a reliable, built-in clock that feels better than the wall timer and paper score sheet they were already using.
Outcome: Tempus became a trustworthy replacement for ad hoc timers, proving the value of real-time training inside BTWB.
Once the core experience felt solid, we focused on making workouts feel shared instead of strictly solo.
Outcome: Training started to feel more social and competitive, even when athletes weren’t in the same room.
Finally, we extended Tempus into the full class environment, giving coaches and athletes a shared view of the workout as it unfolded.
Outcome: Tempus became part of how classes were run — not just a personal tool, but a shared performance surface for the entire room.
Tempus introduced a new level of training inside BTWB:
Together, these features transformed Tempus into a real-time performance layer that supports solo training, remote sessions, and full class environments.
While formal analytics weren’t available, usage patterns, community feedback, and ongoing investment in the product made the impact clear.
What began as a new way to train quickly became part of how many athletes structure their workouts. Once set up, Tempus fades into the background — it’s there when you need pacing, splits, or a race, and invisible when you don’t.
Live leaderboards and shared views helped athletes feel like they were training together, even when they weren’t in the same room. In class settings, coaches and athletes could see progress unfold in real time.
By surfacing pacing, splits, and performance in real time, athletes could make smarter decisions during a workout, not just reflect afterward. Training sessions felt more intentional and more engaging.
Tempus laid the groundwork for richer insights and more connected training across the BTWB ecosystem, turning real-time training data into something the product can build on for years to come.
Tempus represents a major evolution for BTWB — shifting from a historical record of training to a live, connected experience that shapes how athletes move, pace, and compete in the moment.
As Lead Product Designer, I drove the vision, interaction design, and visual language for this 0→1 product across multiple devices. The work demonstrates my ability to design for complex, high-intensity contexts, align cross-functional teams, and ship experiences that become part of users’ everyday routines.
