NexFlow
Run health experiments on yourself.
Connect your watch. Try something for two weeks, like cutting coffee or sleeping more. We'll show you proof of what actually changes your energy, sleep, and focus forever.
Working with faculty advisors at top universities
How it works
Three steps to finally understand your body. No lab visits. No guesswork.
1. Connect your wearable
Sync your Apple Watch, Apple Health, Oura, or Whoop in seconds. We start learning your baseline immediately.
2. Run a 2-week experiment
Pick something to test: no caffeine after noon, 10k steps daily, or cold showers. We track everything automatically.
3. See what actually changed
Get clear before/after comparisons of your sleep, energy, and focus. Keep what works. Drop what doesn't.
