Level up your life
You, compared to you. In the chapter of life you're actually in.
EraVyr brings your available device readings and the reflections you choose to record into one place, with their dates and sources. See actual measurements and your own ratings without turning them into a single wellbeing score.
And every stat says where its number came from. Measured means a sensor read it. Reported means you said it. They are never mixed, never averaged together, and a self-report is never dressed up as a measurement.
A small, invitation-only beta. Request access first; Michael will confirm your device setup and send an invitation. A request does not create an account.
Illustrative values, not a live account or a screenshot. Missing or old inputs are labeled rather than filled with an invented number.
The core idea
Your readings and reflections, in context.
Activity is shown in steps or minutes, HRV in milliseconds, and supported glucose readings in their original units. Vitality summarizes available body signals without combining them into a health score.
When enough earlier readings exist, EraVyr compares a signal with your own history from the same source and estimator. Above or below your usual range describes a pattern, not whether you are healthy.
Chapters keep the story behind your data
Record changes in your routine or life and revisit previous chapters. Current measurement comparisons use a rolling historical reference; starting a chapter does not reset or retrain that reference.
Sources stay visible
Measurements and self-ratings stay separate.
Vitality · Activity · HRV · Glucose
Available device signals retain their units, source, observation dates and coverage. Not every connection supplies every signal.
Calm · Clarity · Connection
Your direct, dated 1–10 ratings. Device context does not change how you rate your own experience. Calm does not require HRV.
Spark · your own tiles
Name what matters to you and record a 1–10 rating. Your ratings do not change measured signals.
Your first readings
You can see inputs before a comparison is ready.
A saved self-rating can appear immediately. Device summaries use the seven completed calendar days before today and average only days with actual readings. Today’s incomplete day is excluded.
A personal comparison needs at least ten distinct reading days in the ninety-day period before that seven-day window, from the same source and estimator. There is no fixed two-week wait for every tile.
Device inputs more than three account-calendar days old and self-ratings more than seven days old have no current numeric value. Their historical dates remain visible. Missing readings do not become zeros or a default 50.
Privacy, stated precisely
Know the route your data takes.
Read the data-handling details before connecting a source. The route depends on the connection you choose, and the hosted service processes your readings on EraVyr’s server.
Connections have different routes
Apple Health and Health Connect use your phone’s health store and the EraVyr beta app. Direct Oura uses Oura Cloud after your authorization. No advertising pixel is added to your dashboard.
Your name isn't stored next to your numbers
Your readings live in their own file — not rows in one shared table with everyone else's — and that file is named by a random ID. It contains no name and no email. Those live somewhere else entirely, in a separate vault, encrypted at rest (as are your lab results, medications, and the raw values behind each reading). Separation reduces direct identification; it does not make health readings anonymous.
Compared only to you
Your baselines are computed from your data alone — never pooled with anyone else's, never sold, never used to train a model that reaches other people. Comparisons keep sources and estimators separate.
Where the thinking happens — the unflattering bit
The learning runs on Eravyr's server, not on your phone. The app in your browser is a display for results computed elsewhere. Plenty of apps in this category imply the reverse, because it sounds better in a headline. It wouldn't be true of the hosted version, so we don't say it.
No password to steal
Sign in with a one-time link sent to your invited email address, then press the sign-in button on the page. Keep that link private.
Export everything. Delete means delete.
Take your whole history with you whenever you want. And when you delete your account, it's really deleted — not flagged, not archived, not "retained for legitimate business purposes." One honest caveat: encrypted nightly backups exist so a server failure can't erase everyone, and a deleted account lingers in those until they age out.
There's a page that lists exactly which fields are encrypted and which ones deliberately aren't, and why — including a section titled "Not encrypted — on purpose." Read it before you trust us, not after.
Current beta access
Choose a supported setup before connecting.
- Web dashboard: invited users can sign in, record check-ins and review their tiles and chapters.
- iPhone/iPad: the native app is distributed to invited testers through TestFlight. It reads supported steps, resting heart rate, HRV and workouts after pairing and permission. The current native reader does not read Apple Health sleep.
- Android: a native Health Connect beta is available by arrangement with Michael. It can read only supported categories already present in Health Connect. Do not install a similarly named app from a store search.
- Oura: a direct connection is implemented for selected readings, including nightly HRV. Each wearer must authorize it; successful connection and first imported readings must be checked. It is not a promise that every ring is already syncing.
- Pet readings: an experimental, restricted family Fi pilot exists. It is not a generally available or officially supported Fi integration; unattended collection remains unverified.
- Background sync: phone scheduling and permissions affect delivery. Open the app and check its last accepted upload and individual reading dates; a connected account alone is not proof that readings arrived.
- General wellness: EraVyr reflects patterns; it does not diagnose or replace a clinician.
What it costs
The private beta is free; billing is not open.
The prices below are previously announced plans, not products you can purchase today. No paid trial or checkout is open.
Eravyr Cloud
$5.99 / month
or $59 a year, if you'd rather think about it once.
- Nobody is being charged today. There is no checkout yet — the beta is free while it's a beta. This is what it will cost when that changes, published early so it can't surprise you later.
- Runs on Eravyr's server. Nothing to install, nothing to maintain, works on whatever you're holding.
- When billing opens, cancelling will be a button in the app — not an email to me, not a phone tree, not four screens of "are you sure."
- It's a subscription because it runs on a server that costs money every month. That's the entire reason.
Eravyr Private Edition
$140 once
A download, not a box in the mail.
- Self-hosted: you run it on hardware you already own, and local storage is the intended design. External connections, if used, still involve their providers.
- One-time rather than monthly for a boring reason — on your machine, it costs Eravyr nothing every month. The cloud version costs us every month, so it charges you every month.
- You cannot buy this today. There's no button below because there's nothing to click yet. If you'd want it, tick the box in the form — that tick is the vote that decides whether it gets built.
No payment needed to request access
Requesting a beta invitation does not start a subscription or a paid trial. Any future billing launch and its terms will be communicated separately.
Where we are
A small private pilot, built by Mike Nance.
EraVyr is being tested with invited users. Native builds, account connections and successful imports have separate states: availability of a build does not establish that it is installed or syncing on every phone.
Mike builds the product and handles beta setup and feedback. Request access below; he will confirm whether the current beta fits your device and needs.
Beta signup
Ask for a seat in the beta.
No countdown timer, no "spots remaining." Tell me your email, tick what you'd actually use it for, and I'll get back to you like a person.
