Your Brain Has a Peak Hour.
We Find It.
Nulve connects your nutrition, sleep, and cognitive performance to predict exactly when your mind is sharpest — so you can do your best work then.
Precision tools for peak performance
Snap & Analyze
Point. Shoot. Done. AI breaks down your meal's brain impact in seconds — no logging, no searching, no willpower required.
Know Exactly When To Do Your Best Work
Most people guess. Founders block 9am because it feels productive. Students grind at midnight hoping it sticks. Nulve calculates your Deep Focus Window daily — based on what you ate, how you slept, and your real cognitive scores. One specific time slot. No guessing. No wasted hours.
A Coach That Knows Your Data
Ask why your focus dropped. Ask what fueled your sharpest day this month. Nulve's AI doesn't guess — it pulls from your real Clarity Scores, meals, and sleep to surface patterns you can't see on your own. Personalized answers, grounded in your actual performance data.
Four Tests. 60 Seconds. Real Clarity.
Reaction time. Processing speed. Working memory. Attention control. Each test measures a different dimension of your cognitive performance — so your Clarity Score reflects how your brain is actually performing right now, not how you think it is.
Why Nulve works differently.
Your brain has a peak. We find it.
Every day your brain peaks in a specific window — and most people waste it in meetings, emails, and distractions. Nulve finds it so you never miss it again.
Stop guessing. Start executing.
The people outperforming you aren't working harder. They know when their brain is actually ready. Nulve gives you the same edge — predicting your exact focus window so every deep work session counts.
Works with Apple Health.
No wearable needed. Nulve reads your Apple Health sleep data and automatically factors it into your focus prediction every single morning.
Your brain performs differently every day.
Nulve finds the pattern.

Built for Peak Performers
Solo Founders
You're running on fumes and making decisions that could make or break your company. The problem isn't your work ethic — it's that you're doing your hardest thinking at your worst hours. Nulve finds the 2–3 hours a day when your brain is actually sharp and tells you exactly what to put in them.
Students
The students hitting top scores aren't studying more than you. They're studying at the right time. Nulve shows you when your brain absorbs and retains the most — so every hour you put in actually counts toward the grade, not just the hours logged.
Remote Workers
You have something office workers don't — full control over your calendar. Nulve gives you the data to use it properly. Know exactly when to block deep work, when to take meetings, and when to step away. Then watch your output speak for itself.
