Stop chasing protocols
that weren't built for you

ΔN1 runs experiments on YOUR data and proves what actually works for your biology. Not generic advice. Not guesses. Your proof.

Here's what that looks like:

"I blamed caffeine for my 3pm crashes for years. ΔN1 analyzed 47 days of my data and found the real answer: lunch timing. Now I have the data to prove it."

  • Discover personalized insights about YOUR biology—most users see their first validated pattern within 30 days
  • Know exactly when to eat, push, and rest based on YOUR patterns
  • Stop guessing. Start knowing.

Works with Apple Health, Garmin, and your calendar

You're already tracking. It's not working.

Wearables give you scores. Apps give you dashboards. But nobody tells you what to actually do today.

Scores without action

"Your recovery is 47%." Great. What does that mean for your 10 AM meeting? Most systems give you data without telling you what to do with it.

Generic advice

Caffeine affects everyone differently. So does sleep timing and meal composition. Advice optimized for "average" is wrong for most people. Including you.

Human coaches forget

A great coach costs $200-400/month. And even they can't remember your 47-day energy pattern or how last Tuesday's late dinner affected Wednesday's focus.

The difference is knowing

What changes when you stop guessing and start knowing what works for YOUR body?

Before ΔN1
  • "Your recovery is 47%." Cool. What do I actually do with that?
  • Try intermittent fasting because a podcast said so
  • 3pm crash hits again. Grab another coffee.
  • Wonder if you're doing something wrong
  • Chase the next protocol. Hope this one sticks.
After ΔN1
  • "Peak focus 9-11 AM. Front-load your hardest work." Got it.
  • Protein-first lunch before 12:25. Crash-free afternoon.
  • Know exactly whether today is a push day or recovery day
  • One thing to focus on tomorrow. Not 47.
  • Your own protocol. Proven to work for YOUR biology.

This isn't about being perfect. It's about finally knowing what works.

Your life isn't a protocol. Neither is this.

Most health apps punish you for being human. ΔN1 works with your messy, real life.

Track anything

Not just steps and sleep. Track what matters to YOU. Does afternoon tea help focus? Does working from home vs. the office affect your energy? Does calling your mom on Sundays improve Monday's mood? If you can track it consistently, you can test it.

Respects your constraints

Travel next week? Kids sick? Brutal deadline? ΔN1 adapts. It finds what works within YOUR reality, not some idealized version of your life. No guilt. No judgment. Just what actually works when life gets messy.

Evolves with you

What worked in your 20s might not work now. What worked before the new job might not work after. ΔN1 detects when your patterns shift and re-learns. Your biology changes. Your advice should too.

Morning Check-in

"Good morning! Your deep sleep was 1h 42m. That's 23% above your average. HRV is strong at 58ms. Based on your pattern, you'll have peak focus around 9-11 AM. Consider front-loading your hardest work."

Why this matters: The system learned you're a morning person with cognitive peaks 2-3 hours after waking.

Lunch Timing Alert

"Quick reminder: You've got 7 minutes until 12:25. Based on our experiment, protein-first lunch before 12:25 has been linked to better afternoon energy in my data."

Validated discovery: Effect size +0.34, p < 0.05. This isn't a guess.

Experiment Check-in

"Day 5 of your dinner timing experiment. Tonight is an early-dinner night (before 7 PM). So far, early dinner nights show +12 min deep sleep on average. Still need 9 more days for significance."

Current status: p = 0.18. Trending positive but not yet proven for your biology.

Evening Prep

"Experiment reminder: Dinner by 7 PM tonight. Tomorrow's a big presentation day and your data shows you perform better when sleep latency is under 15 min. Start winding down around 9:30."

Context-aware: Pulled from your calendar integration.

Day Summary

"Great day. You hit your lunch timing window, finished dinner at 6:52 PM (experiment logged), and got 8,400 steps. Tomorrow: focus on hydration. You were 20% below target today."

Tomorrow's priority: One actionable focus, not 47 things to remember.

ΔN1 Coach
Good morning! Deep sleep was excellent last night: 1h 42m. Your HRV is 58ms, which is strong for you. Ready for a productive morning?
6:32 AM
Should I work out today?
6:34 AM
Yes, your recovery metrics are ideal. Your data shows Tuesday strength sessions boost Friday cardio performance. I'd suggest upper body focus, moderate intensity (RPE 6-7).
6:34 AM
Why do I always crash around 3pm?
6:35 AM
I've analyzed 47 days of your data. It's not caffeine. It's lunch timing. When you eat protein-first before 12:25 PM, your afternoon crash pattern improves significantly. Want me to set up a reminder?

Days 8-14

Apply the intervention. Daily reminders keep you on track.

Results
Day 15+

Statistical analysis with real confidence intervals. Did it actually work?

Example: Lunch timing experiment

Hypothesis: "Does protein-first lunch before 12:30 prevent my afternoon crash?"

✓ Validated p < 0.05 · Effect: +0.34 · 9/11 days improved

Real results from real data

On Day 19, something clicked.

I'd always blamed caffeine for my 3 PM crashes. Cut back to one cup. Tried switching to green tea. Nothing worked. Then ΔN1 analyzed 47 days of my data and found the real culprit: lunch timing. When I eat protein-first before 12:25 PM, I don't crash. It's that simple. And now I have the data to prove it.

— Mark, Founder

This is one person's discovery. Your patterns will be different—that's the point.

Validated Discovery Day 19

Your 3 PM crash isn't caffeine. It's lunch timing.

+0.34 Effect size
0.21–0.47 95% CI
p < 0.05 Significance
9/11 Days improved

Protein-first lunch before 12:25 PM → sustained afternoon energy.
Carb-first or late lunch → crash by 2:45 PM (±18 min).

*From founder's personal data. Your results will be unique to you.

Questions you probably have

Here's the process:

  • You'll get a confirmation email immediately
  • We're accepting beta users in batches of ~20
  • When it's your turn (typically 2-4 weeks), you'll get an onboarding email
  • We'll set up a 15-minute video call to understand your goals and get you connected
  • After setup, the system starts learning your patterns immediately

Required: An Apple Watch or Garmin wearable syncing with Apple Health.

Recommended: Google or Apple Calendar integration (helps us understand your schedule and constraints).

Optional but valuable: Sleep tracking app (Oura, Whoop), nutrition logging when requested.

The more consistent data, the faster discoveries. But we start with what you have.

An experiment is a structured 14-21 day test of a hypothesis about YOUR biology.

Example: "Does protein-first lunch prevent my afternoon crash?"

  • Days 1-7 (Baseline): Eat normally. We measure your typical crash pattern.
  • Days 8-14 (Treatment): Protein-first lunch before 12:30 PM. Daily reminders keep you on track.
  • Day 15+ (Results): Statistical analysis with real confidence intervals.

You get a verdict: "This works for you" or "No significant effect detected." Not guesses. Proof.

Two reasons:

1. Regulatory clarity: US consumer wellness apps have clearer regulatory guidelines. We're not medical, but we want to be cautious as we scale.

2. Timezone simplicity: Real-time coaching messages work best when we can calibrate to your schedule. Starting US-only lets us nail the timing before expanding.

We're planning international expansion after the beta period.

Day 60 isn't the end—it's when things get interesting. By then you'll have:

  • Your first validated discoveries about your biology
  • A baseline of what works for YOU
  • A system that keeps learning as your life changes

When we transition to paid ($79/month), beta users get priority access and a lifetime discount. Your discoveries don't expire. The system keeps evolving with you.

No. We're a wellness optimization tool, not a medical device. We help you understand patterns in YOUR data.

For medical concerns, see your doctor—and bring your discoveries. They'll probably appreciate the data.

Yes. Your data is yours. Export anytime in standard formats. Delete everything permanently with one click.

We don't sell your data—ever. See our privacy policy for details.

Mark Koivuniemi

Software engineer · 15 years building data systems

I've worn almost every wearable and read all the studies. The pattern was always the same: follow the protocol perfectly for a while, then real life hits. When I started applying the same rigor I use in data engineering to my own health—running actual experiments with statistical validation—I finally stopped chasing other people's advice.

I built ΔN1 because I wanted a system that respects your constraints, doesn't punish imperfection, and actually learns. I'm limiting beta to 100 users because I want to personally ensure it delivers real value.
