Tyme Wear

What Tyme Wear does

Tyme Wear, Inc. (operating as Tymewear), founded in 2014 and headquartered in Boston, builds consumer wearable hardware and software for endurance athletes. Its flagship VitalPro is a chest strap that combines a breathing sensor (silicone EAP technology) with a heart-rate sensor over Bluetooth Low Energy 5.3, measuring breathing rate, tidal volume, minute ventilation, and heart rate in real time to detect ventilatory thresholds (VT1, VT2) and estimate VO2max. The device's accuracy is anchored by a published validation against the Cosmed K5 metabolic cart (mean absolute error of 1.2 breaths/min for breathing rate; r=0.973 pooled correlation for minute ventilation across 26 athletes). The hardware pairs with a Tymewear mobile/web app (iOS, Android, Garmin IQ, Wahoo bike computers) and a Coach Dashboard for managing multiple athletes, enabling threshold testing, real-time ventilation feedback, and ERG-mode control on indoor trainers. Syncs include Garmin, Intervals.icu, TrainingPeaks, Wahoo, and Apple Watch.

The commercial model is direct-to-consumer e-commerce with three hardware tiers ($299 standalone; $399 1-year bundle; $449 2-year bundle) and an optional ProTraining subscription ($15/month or $150/year) that delivers personalized workouts and daily recommendations derived from the user's thresholds. Distribution is exclusively through tymewear.com, with US and EU fulfillment centers, multi-currency checkout, and 30-day risk-free returns; B2B inquiries route to [email protected]. The company sells primarily to endurance athletes (cyclists, runners, triathletes, cross-country skiers, Hyrox competitors) and their coaches, with a flagship partnership as Official Supplier to Team Visma | Lease a Bike and UCI approval enabling use across the WorldTour racing calendar. Academic collaborators include Stephen Seiler, PhD (University of Agder) and Andrea Nicolò, PhD (Foro Italico University of Rome). Funding history shows a single disclosed round of $1.4M in April 2020, headcount of 1–10, and no disclosed institutional VC/PE backing.

Core offering

Tyme Wear designs and sells the VitalPro chest strap — a wearable sensor that measures breathing rate, minute ventilation, tidal volume, and heart rate — paired with the Tymewear mobile/web app and an optional ProTraining subscription. The system identifies an athlete's individual ventilatory thresholds (VT1, VT2, VO2max) during a 20–30 minute ramp test, delivering lab-grade personalized training zones and daily workout recommendations for endurance athletes.

Product overview

Tyme Wear offers a unified wearable ecosystem centered on the VitalPro chest strap—a sensor device that measures breathing rate, tidal volume, minute ventilation, heart rate, and HRV to detect ventilatory thresholds (VT1, VT2) and VO2max. The ecosystem includes the Tymewear mobile/web App for individual athletes and a Coaching Dashboard for coaches managing multiple athletes. ProTraining is a subscription add-on that provides personalized training recommendations and a customized workout library. Together, these products enable threshold-based training that the company claims improves fitness 2.4x faster than traditional heart rate zone methods. Tymewear has a commercial partnership with Team Visma | Lease a Bike, serving as official supplier to their professional cycling team.

Expansion highlights6 records

Broad incumbents

• Garmin: Garmin manufactures the HRM-Pro chest strap family and the Connect ecosystem that Tymewear integrates into. Direct product competition for the heart-rate chest strap category, plus an integration partner today and the most likely strategic acquirer or competitive threat given ecosystem control.
• Apple (Apple Watch): Apple Watch is the dominant consumer health wearable with HR, HRV, and workout tracking on the wrist. Indirect competition via broader wellness-wearable TAM but lacks chest-strap-grade ventilatory threshold features; relevant as the converged-device threat Tymewear must argue against.
• Suunto: Suunto produces sports watches (Vertical, Race) and accessories for endurance athletes including chest-strap-compatible HRMs. Same endurance buyer and structured-training positioning, with broader GPS-watch portfolio that competes for the same training ecosystem dollars.
• Fitbit (Google): Fitbit produces consumer fitness wearables (Charge, Sense, Versa) with subscription-based health insights. Comparable on subscription-wearable GTM model and broad-fitness positioning, though without chest-strap-grade ventilatory threshold detection.

Emerging players

• Stryd: Stryd makes a footpod that delivers running power and critical power metrics for runners and triathletes. Compares to Tymewear on the running-endurance persona and on the philosophy of bringing lab-grade physiology to field training, though it focuses on power rather than breathing.
• COROS: COROS makes endurance-focused GPS watches (Apex, Vertix) with built-in optical HR and structured training features for endurance athletes. Partial overlap on the endurance-athlete persona but diverges on form factor (wrist vs. chest) and lacks ventilatory threshold detection.

Direct peers

• Whoop: Whoop sells a subscription-based health/fitness wearable (the Whoop strap) that monitors physiological signals and delivers recovery/strain insights. Same hardware-plus-recurring-subscription go-to-market model applied to a broader (not endurance-specific) athlete base — the closest analog to Tymewear's business model.
• Polar Electro: Polar's H10/H9 chest straps are the legacy gold-standard HR chest strap used by serious athletes for decades. Same target buyer (endurance/coaching), same form factor (chest strap), with Polar Beat and Polar Flow providing the software layer analogous to Tymewear's app.
• Wahoo Fitness: Wahoo's Tickr and Tickr FIT chest straps target the same cyclist/runner/triathlete buyer that Tymewear serves. Wahoo is also an integration partner (Elemnt bike computers), making it both a competitor and a channel — and a credible strategic acquirer given its cycling-system focus.

Others

• Cosmed: Cosmed manufactures the K5 metabolic cart — the gold-standard lab equipment against which Tymewear validates its chest strap. Cosmed is the incumbent Tymewear is displacing for routine testing; relevant for understanding the ~$30K+ lab replacement value-prop economics.
