Key features

Vyla Band — built for cycle tracking

The Vyla Band is Vyla's own dedicated wearable, coming soon. Designed specifically for women's cycle tracking, it will stream continuous temperature, heart rate, sleep, and activity data directly into Vyla — no third-party app required.

Temperature trends from your wrist

Apple Watch Series 8 and above track wrist skin temperature during sleep. Vyla layers this data over your cycle timeline to reveal temperature patterns across your menstrual, follicular, ovulatory, and luteal phases.

Cycle-phase wellness view

See how your heart rate, resting heart rate, sleep quality, and activity levels from your Apple Watch or Fitbit track across each phase of your cycle — all in one place.

Ovulation temperature signal

Apple Watch Series 8+ can detect the subtle overnight temperature rise that typically follows ovulation, giving you a passive signal to complement your BBT and LH test logs in Vyla.

Unified data timeline

Your wearable's readings sit alongside your logged symptoms, period dates, mood, and energy in a single Vyla timeline — no switching between the Health app or Fitbit app.

AI-powered pattern questions

Ask Vyla AI why your sleep or heart rate dips at certain points in your cycle. Get clear, jargon-free explanations based on your combined wearable and cycle data.

Private sync

Vyla accesses only the wearable data you authorise via Apple Health or Fitbit. Your data is never sold to advertisers or third parties. Disconnect your device or delete your data at any time.

What is the Vyla Band?
The Vyla Band is Vyla's own dedicated wearable built for women's cycle tracking. It tracks temperature, heart rate, HRV, sleep, and activity 24/7 and syncs directly to Vyla — no third-party app needed. It's coming soon — join the waitlist on the Vyla Band page.
What wearables does Vyla support?
Vyla integrates with Apple Watch Series 8 and above (via Apple Health) and Fitbit devices. These wearables provide temperature, heart rate, sleep, and activity data that Vyla layers over your cycle phases.
Which Apple Watch models work with Vyla?
Apple Watch Series 8 and above are required for wrist skin temperature tracking, which is the key data Vyla uses for cycle-phase insights. Earlier models still sync heart rate, sleep, and activity data via Apple Health.
Does Vyla work with Fitbit?
Yes. Vyla connects to Fitbit devices to pull heart rate, sleep, and activity data. This data is displayed in the context of your logged cycle phases to show how your body responds across each phase.
Can Apple Watch detect ovulation?
Apple Watch Series 8+ measures wrist skin temperature during sleep, which can reflect the small overnight rise that typically follows ovulation. It is not a definitive indicator of ovulation — Vyla combines it with your logged BBT, LH tests, and symptoms for a fuller picture.
Do I need a wearable to use Vyla?
No. Vyla works fully without any wearable. You can manually log BBT, LH tests, symptoms, and period dates. Wearable integration is an optional feature that adds richer passive data.
Is wearable integration free?
Yes. Wearable integration is included free in Vyla, alongside full manual cycle tracking, period logging, and predictions.
