Smarter training days for women

Daily training call: Push · Steady · Recover

Coach-simple. On-device. No new hardware.

What it does

📊

12-minute morning check — balance, finger taps, 5× sit-to-stand, quick HRV.

Works with or without a wearable — rolling baseline if you don't use one.

🌙

Cycle-aware — adjusts for phase so the call is fair and consistent.

Pilot Success (any 2)

  • Compliance ≥ 70%
  • 5% better at detecting bad days vs wearable-only
  • 20–30% fewer late-luteal false Recover flags

FAQ

Do I need a wearable?

No. Wearables help but are optional. The 12-minute check plus phase-aware baselines are enough to produce a daily call.

What's in the 12-minute check?

Seated→standing HRV (if available), single-leg balance, 30-second finger taps (both hands), 5× sit-to-stand, soreness, readiness.

What do coaches receive?

A morning list with Push/Steady/Recover per athlete and a weekly 1-pager. No dashboards.

How is data handled?

Wellness-only. Private by default. We share today's call and weekly aggregates with staff. Athletes can withdraw anytime.

What's 'phase-aware'?

We compare each athlete to her rolling, phase-aware baseline to avoid late-luteal false 'under-recovered' flags common in generic algorithms.

About the Founder

Adriana Tavarez is a Mount Holyoke College student and United States Air Force service member building PhaseTwin to solve a problem she knows firsthand: training readiness tools that ignore women's physiology. As an active woman balancing military service and academic excellence, she's experienced how generic algorithms flag late-luteal phase changes as "under-recovery"—when nothing is wrong.

PhaseTwin combines neuromotor checks with phase-aware baselines to give coaches accurate Push/Steady/Recover calls that actually work for female athletes. Pilot programs aim to reduce injury rates and improve performance by making training readiness tools designed for women, not retrofitted from men's data.
