Side by side

The full comparison.

NOWATCH next to the Oura Ring 5, Apple Watch Series 11, and WHOOP 5.0 — every feature and spec.

What makes NOWATCH different

NOWATCH takes a different approach from every tracker in this table. No pings, no daily scores, no streaks — it stays silent unless something genuinely needs your attention. Research-grade sensors capture raw signals every second, 24/7 — where Oura Ring 5 and Apple Watch sample at intervals — calibrated to your personal baseline, not a population average. Its Reactivity Monitor™ delivers a minute-by-minute timeline of everything your body goes through, tracking stress duration, recovery time, and frequency — metrics no other tracker in this comparison captures. Free app, no subscription — and your data stored on EU-based servers, under European law.

Frequently asked questions

What does this comparison cover?

Every feature and spec of NOWATCH side by side with the Oura Ring 5, Apple Watch Series 11, and WHOOP 5.0 — from stress and sleep tracking to battery life, subscriptions, and data privacy. Battery life and prices reflect the current releases: WHOOP 5.0 / MG (May 2025), Oura Ring 5 (May 2026), and Apple Watch Series 11 (Sep 2025).

What makes NOWATCH different from other health trackers?

Most trackers reduce your health to daily averages — sleep score, readiness, strain. NOWATCH's Reactivity Monitor™ tracks how your body responds to daily demands every second, 24/7, calibrated to your personal baseline, not a population average. That continuous precision is what makes NOWATCH's metrics meaningful: stress duration, recovery time, and frequency — and how they build into cumulative load over time, a key indicator of long-term health risk. No subscription, no gamification. Your data stored in the EU, under European law.

Does NOWATCH require a subscription?

No — the NOWATCH app is free, with no subscription needed. By comparison, the Oura app costs $5.99 per month or $69.99 per year, and WHOOP membership runs from $199 up to $359 per year. The Apple Watch app is free as well.

How does NOWATCH measure stress?

NOWATCH captures heart rate and movement signals every second and our proprietary Reactivity Monitor™ processes those signals into a minute-by-minute timeline of how your body responds to daily demands. Based on your personally calibrated baseline (called homeostasis), it detects stress responses, measures stress duration, recovery time, and frequency (how long your body takes to return to homeostasis). Physical activity is automatically flagged so you can read the rest of the timeline clearly, and a feelings Check-in lets you add context the sensors alone can't capture.

What happens to my data with NOWATCH?

You can download and export your raw data anytime. NOWATCH stores it on EU-based AWS servers in Frankfurt with advanced encryption and applies GDPR-level privacy wherever you are. Unlike NOWATCH, none of them offer sensor-level raw data export, and none store your data exclusively on EU-based servers.

Where can I see NOWATCH against one specific tracker?
