TRAIN SMARTER

with Lucid Athlete for iOS

Because Smarter Athletes Are Better Athletes™


Lucid Athlete is an iOS app that analyzes your body's vital signs to estimate your true aerobic fitness, recovery and ability to perform.

All you need is an Apple Watch (or other compatible wearable).

You don't need more crap on your arm

If you've already got an Apple Watch, you don't need a dedicated armband, or a sky-high subscription to track your fitness and get actionable insights. The Apple Watch has been shown to be competitive (and sometimes even more accurate) than niche fitness wearables.1,2,3 Lucid just helps you unlock its potential.

Clean, intuitive & easy

Data is fun. But data for the sake of data? Not so much 🙄
With Lucid, you get the clear, simple insights to help you train smarter. Get better, more actionable data-driven insights at your fingertips than ever before.

Backed by science

Lucid's proprietary algorithms and insights leverage peer-reviewed scientific studies. We don't make stuff up. Because you should expect nothing less.4

Lucid Score

Check your body's stress response to training and spot when you're fighting off a bug.

True Aerobic Score™

Most "fitness scores" are really tracking your effort, not your actual fitness.
Lucid is different.

Key Metrics

Lucid Athlete covers all your key athletic performance metrics including HRV and sleep trends.

BETA TESTERS WANTED

We're looking for beta testers to help improve Lucid Athlete and guide its development. Accepted beta testers get free access to Lucid Athlete for as long as it's in beta.
