Leaderboard shows beta practitioner data. All handles are self-selected anonymous IDs. HRV delta is average RMSSD change per session vs baseline. Full community leaderboard opens April 18.

Trajectory

What the leaderboard data will look like at 6 months. At 1 year. Why the gap between them matters.

Most leaderboards are just rank lists. This one accumulates predictive signal over time. Here is what the data will reveal as the community grows.

At 6 months
The session count patterns emerge
01

Time-of-day clustering becomes visible. Most practitioners settle into a consistent session window within 60 days. The community aggregate shows morning, midday, and evening as distinct use-case clusters with meaningfully different HRV response profiles.

02

Frequency band preference stabilizes. At 6 months, roughly 70% of active users have a dominant band they return to. The leaderboard will show band-by-band response norms for the first time, making personalization recommendations sharper for new users who join later.

03

The attrition signal. Who stopped logging sessions and when. This tells us which protocol configurations were not working and leads directly to recommendation engine improvements.

At 1 year
The baseline trajectory becomes predictive
01

HRV trajectory curves. At 12 months of logged data, users in the top quartile of session consistency show a measurable baseline HRV slope. The aggregate makes this visible as a community average, and your personal trajectory sits in context. You can see whether you are tracking above or below the community curve for your starting RMSSD.

02

Cohort comparisons become actionable. A user who joins in month 8 benefits from 8 months of community session data. Their first-week recommendations are calibrated against users who already found their optimal band. The leaderboard acts as compounding institutional knowledge.

03

The top 50 practitioners at 12 months will have the highest-density personal matrices in the system. Their response profiles feed the recommendation engine directly. The community's most consistent practitioners make the app better for everyone who comes after them.

Why founding members have a different relationship to this data

Users who join at launch contribute to the baseline that defines what "normal" means in this system. The community norms at month 1 are built from founding member data. If you are here at the start, you are not just a user. You are one of the reference points against which every future protocol recommendation is calibrated.

What the community data tells us. +
Aggregate session data

What the community data tells us.

Every session logged anonymously across the community creates a dataset that would be impossible to generate from individual data alone. Here is what it shows so far.

Peak session hour
6:45am

Most sessions start between 6-7am. The Cortisol Awakening Response window. The community found this before we documented it.

Most-reached frequency
10Hz

Alpha is the most-used band community-wide. Followed by 40Hz gamma. Delta lags both, despite having strong evidence for sleep improvement.

Avg session duration
19 min

Shorter than the protocol-recommended 20-30 minutes, but long enough for measurable HRV response in most users. Consistency beats duration.

Repeat-session rate
76%

Of users who complete 3 sessions, 76% return for a fourth within 7 days. The first three sessions are the retention gate. Beta cohort, n=86 sessions.

Data from beta cohort (n=86+ sessions). Community HRV aggregate will update post-April 18 when Apple Watch users are onboarded at scale. Session counts and frequency data are live from the database. HRV delta requires HealthKit integration to appear.

Sessions earn your position. Consistency compounds it. +
How ranking works

Sessions earn your position. Consistency compounds it.

Your rank is determined by session count, not by who paid more or joined first. Every logged session advances your position. The leaderboard resets to zero at launch on April 18 so every founder starts equal.

HRV delta is displayed as a signal, not a ranking variable. A practitioner with +4ms and 60 sessions outranks one with +22ms and 8 sessions. The research value is in consistency. Outlier results from single sessions are noise.

What counts as a logged session
YES
Browser session of at least 8 minutes with a valid frequency selected
YES
Any full protocol stack (Hz + breathwork + posture)
NO
Previews, page loads, or sessions under 4 minutes
NO
Multiple sessions within 10 minutes (deduped server-side)
Beta cohort averages
4.2
Sessions / week · active practitioners

Practitioners who logged sessions 3+ times per week showed measurable HRV trend lines by day 14. Below 3 sessions per week, the signal is too noisy to trend.

6:47am
Median first session time

67% of beta practitioners run their primary session before 8am. The morning cortisol window is the most popular entry point. Evening delta sessions (9-11pm) are the second most common.

40Hz
Most-used band · all-time

Gamma (40Hz) is the most-used band across the beta cohort, followed by 2Hz delta and 10Hz alpha. Practitioners using the voice intake protocol are 2.3x more likely to stay in their prescribed band.

Handles are self-assigned on first login. You can set yours on the account creation screen. The system generates a random ID if you skip the field. HRV data is only surfaced in aggregate and is never linked to individual identifiers.

What happens to the community signal when more people practice every day. +
Consistency effect

What happens to the community signal when more people practice every day.

The community dataset is not just a leaderboard. It is a live research signal that improves in resolution as session density increases. Here is what changes as the community grows and practices consistently.

At 500 sessions/week

Time-of-day accuracy improves.

The "peak hour" statistic (6:45am right now) has enough resolution to break down by frequency band. The dataset can tell you not just when people practice, but which frequencies dominate at each hour. That is the recommendation signal that drives the morning page.

Current status: usable but coarse. Improves sharply above 1,000 sessions/week.

At 2,000 sessions/week

Cohort comparisons become valid.

At this density, the dataset can split by age bracket and activity level and still have statistically meaningful group sizes. Your community percentile rank shifts from "compared to everyone" to "compared to people whose baseline profile matches yours."

Target launch milestone: April 18 cohort reaching this threshold by day 90.

At 10,000+ sessions/week

Individual recommendations get sharper.

The matrix personalization engine can identify user profiles that closely match your session history and HRV trajectory. Instead of "the community runs alpha in the morning," it can say "people with your profile who switched from gamma to alpha after session 12 saw the highest 60-day HRV improvement."

This is the network effect. Every session makes the recommendation better for everyone.

The more consistently you practice, the more useful the community signal becomes for you and for everyone else. This is not a pitch for engagement. It is the mechanism by which the dataset improves.

What to do with your community position. +
Navigation guide

What to do with your community position.

Your rank is one signal. Here is how to read it and what to do next depending on where you are in the leaderboard.

Top 10

You have enough data to publish.

If you are in the top 10 by session count, you almost certainly have a meaningful HRV trend line on your personal matrix. That data is research-grade. Consider sharing your protocol stack with the Rock Bird journal for inclusion in the next community HRV report.

Sessions 10 to 50

Your best frequency is starting to emerge.

In this range, your band breakdown on the personal matrix will start showing one or two frequencies pulling ahead on RMSSD delta. If you have Apple Watch data, the trend chart is the most important thing to check right now. If you don't, this is the window where adding HRV measurement produces the biggest information gain.

Sessions 1 to 10

You are building baseline. Nothing to optimize yet.

The first 10 sessions are calibration. The AI is learning your voice and your state range. Your HRV baseline is being established. The most useful thing you can do is vary the frequency bands across these sessions (do not repeat the same Hz every time) and log a voice intake at least 5 of the 10 sessions. The pattern recognition requires variation.

April 18 note

The leaderboard resets to zero for all users at April 18 launch. Your beta sessions are logged and count toward your personal matrix, but the launch leaderboard starts equal for every practitioner. The practitioner who logs the most sessions in the first 30 days earns the first permanent top-10 rank.

What the community dataset can answer that individual data cannot. +
Why this data matters

What the community dataset can answer that individual data cannot.

Individual HRV data tells you whether your protocol is working. Community HRV data, aggregated and anonymized, can answer questions that no individual data set can.

Question 01

Which frequency produces the highest median HRV delta at a population level?

Individual variation is high. One person's highest-response band is another person's null result. But at 500+ sessions, the community data starts showing whether any band consistently outperforms across profiles. Current early data: 10Hz alpha shows the highest median delta. 40Hz gamma shows higher peak delta for a subset of users but more variance.

Question 02

Does time of day matter more than frequency choice for HRV outcome?

The individual data suggests yes - morning sessions before 10am produce consistently larger deltas than evening sessions for most users. But whether this is a frequency-independent effect or an interaction between cortisol levels and entrainment response requires cross-user data to answer. This is exactly the kind of question the community dataset is built to answer post-April 18.

Question 03

Does the April 18 global synchronization produce measurably different outcomes than solo sessions?

This is the specific scientific question April 18 is designed to test. The hypothesis is that synchronized group frequency sessions produce different HRV outcomes than the same session done alone. We do not know if this is true. The data from the event will be compared to individual user session baselines to answer it. It will be published in Rock Bird within 24 hours.

Question 04

Does session streaking (no gaps more than 48 hours) produce meaningfully higher long-term HRV trends?

The streak counter in the community sidebar is not decorative. It is a variable the community dataset tracks. Preliminary individual data suggests that users with no gap longer than 36 hours in the first 30 days show faster baseline HRV improvement than intermittent users. At 1,000+ users this becomes statistically testable. That data will be published when we have it.

How your session becomes a published data point. The full pipeline. +
The research pipeline

How your session becomes a published data point. The full pipeline.

Every session produces data. Here is what happens to that data between your Apple Watch reading and the Rock Bird journal publication.

01
Session ends. Apple Watch reads post-session RMSSD.
HealthKit records a 1-minute HRV reading immediately post-session. The app captures the timestamp and pairs it with the pre-session reading from the same watch session window. This pair is the unit of data.
02
Delta is stripped of identity before storage.
The HRV delta is stored against a session ID, not a user ID. Your name, email, and Apple account are never attached to the physiological data. The session ID is a random string generated at session start with no link to your account credentials.
03
Rock Bird runs weekly aggregate analysis.
Every Sunday, a summary of the previous week's community sessions is run: mean delta by band, delta distribution, time-of-day variance, and any outlier patterns. When the dataset reaches threshold (currently: 30+ sessions per band), the summary is published as a Rock Bird data note.
04
Individual users see their own data reflected in the community chart.
Your personal matrix shows where your delta sits relative to the community distribution for each band. If you are in the 85th percentile for alpha response, you see that. The population curve includes your sessions but cannot be traced back to you.
05
Findings with strong enough signal get submitted to peer review.
When a pattern in the community data reaches p < 0.05 with n > 200 sessions, Rock Bird prepares a formal methods summary and submits to a relevant journal. This has not happened yet. The data collection starts April 18. The goal is first submission within 18 months of launch.
Four scheduled community sessions after the launch event. +
Beyond April 18

Four scheduled community sessions after the launch event.

The April 18 event is the first global synchronized session, not the only one. The community calendar already has four more scheduled sessions through the rest of 2026, each designed around a specific question the community dataset can answer. Participation is always optional; the data contribution is always anonymous.

Session 02
May 17, 2026
6:30 PM ET
Gamma versus Schumann, head to head

The community splits into two randomly assigned groups. Half run 40Hz gamma; half run 7.83Hz Schumann. Both groups have their HRV tracked pre and post. The aggregate comparison is published in Rock Bird the following Monday. The experimental question: does gamma or Schumann produce a larger acute parasympathetic response at a population level?

This is a randomized crossover within a single population. We have not seen this design run in binaural research before.

Session 03
June 21, 2026
Summer solstice, 6:30 PM ET
The solstice session, 2Hz delta worldwide

The longest day of the year in the northern hemisphere. The shortest in the southern. A 20-minute 2Hz delta session run simultaneously at 6:30 PM ET. The experimental question: do participants in the two hemispheres show different HRV responses to the same protocol at the same moment? Geographic HRV variation has never been measured at this scale.

Expected participant volume: the April 18 event count, plus three months of growth.

Session 04
September 13, 2026
6:30 PM ET
Breathwork stack comparison night

Four groups, each running 10Hz alpha with a different breathwork pairing: cyclic sighing, box breathing, 4-7-8, and coherent breathing at 5.5 bpm. All four groups have identical frequency carriers. The experimental question: at a population level, which breathwork pairing amplifies the alpha effect most reliably? Balban 2023 answered part of this in a small lab. This runs at community scale.

Randomization is assigned at intake. You do not get to choose your group.

Session 05
December 21, 2026
Winter solstice, 6:30 PM ET
The year-end data session

A repeat of the April 18 protocol: 25 minutes, 7.83Hz, same warm-up, same close. The goal is a paired comparison. Users who participated in April and December get to see their own individual year-over-year delta in their personal matrix, and the community aggregate compares April 2026 to December 2026. This is the first direct longitudinal measurement the community dataset makes possible.

Eight months between the two data points. First time-series replication at this scale.

Every session above has an experimental question attached to it. This is the specific thing that distinguishes the Mortis community calendar from "another guided meditation." We are running real experiments with consenting participants and publishing the results. No session is put on the calendar unless the community dataset can answer a question from it that has not been answered elsewhere. The calendar is a research protocol, not a content schedule.

First-week experience

What the community page actually looks like in your first week.

Most new users expect a social feed. The community page is not that. It is a dashboard that shows where your physiological responses sit against the rest of the cohort, with zero social pressure and no public posts. Here is what you see when you open it on day 1, day 5, and day 14.

Day 01

Empty state, with context

A distribution chart of community HRV deltas by band, with "you are not yet on this chart" noted clearly.
The top of the community leaderboard is visible, but your row is greyed out with "first session pending."
A call to run your first session to appear on the chart. No notifications. No urgent prompts.
The weekly Rock Bird community summary from the previous Sunday, available for reading.
Day 05

You appear on the distribution

Five sessions recorded. Your personal median delta per band is now calculated and visible as a single dot on the community distribution chart.
The leaderboard shows your session count relative to the rest of the cohort, with your band mix at your side.
The community percentile for your strongest band appears. Example: "Your 10Hz alpha response is in the 62nd percentile of the community."
No social prompts. No "encourage another user" buttons. No comments.
Day 14

Comparison becomes useful

Your 14-day HRV trend plotted against the community average for users with similar starting HRV.
The Rock Bird analysis now references your session count (anonymously) in the weekly aggregate.
A "similar trajectories" view shows users whose 14-day curves are closest to yours. No names, no contact. Just the shape of the curve.
Personal matrix reaches first decision point: is your starting band working, or should the matrix suggest a band switch?

The design choice: social comparison is off by default. You see the population curve and your place on it, not other users' faces. The beta cohort feedback on this was unanimous - a social feed would have been the fastest way to corrupt the signal. Meditation done for community approval looks nothing like meditation done to move an HRV number. We built the second thing.
