# EveryBand

Boop is becoming EveryBand. The iPhone app and TestFlight listing still use Boop for now.

> EveryBand is an independent, local-first health companion for iPhone, with Sleep,
> Recovery, Strain, activity, optional Apple Health access, and an optional
> one-time Boop Full purchase. Direct Bluetooth integration covers WHOOP 4.0, WHOOP 5.0 and WHOOP MG, with model and firmware limits.

## Apple Health input — current TestFlight beta

The current TestFlight beta includes optional Apple Health input, with or
without a strap. It reads sleep, HRV (SDNN),
resting heart rate and activity recorded by Apple Watch or other Health sources.
It is not a live Apple Watch stream or a watchOS app. Direct strap Bluetooth
features remain available. Data availability depends on permissions and recorded
measurements. EveryBand's documented Health HRV input uses SDNN and stays
separate from the local nightly RMSSD estimate. The documented Recovery model
requires nightly RMSSD, resting heart rate, Sleep and sufficient prior nights;
Health SDNN does not substitute for RMSSD. Health input alone does not guarantee
Recovery. A gated local nightly RMSSD estimate can be available from admitted
strap intervals; generic experimental RR variation is not qualified RMSSD or
Health HRV. Local estimates do not establish verified beat timing, wear state,
ECG accuracy or eligibility for Health SDNN export. Missing readings remain
unavailable. Methods describe reviewed implementation; installed beta builds may differ.

## Core facts

- The EveryBand iPhone app requires no account or paid subscription and has no health-data cloud, advertising, or analytics.
- Strap and Health data are processed on the user's iPhone locally. Ask Boop uses Apple Intelligence when available and deterministic on-device guidance otherwise.
- Check TestFlight for available builds and device requirements: https://testflight.apple.com/join/gp8UnyJy
- Canonical website: https://every.band
- Legacy website redirects: https://boop.band, https://www.boop.band, https://boop.x70.one and https://www.boop.x70.one
- Deprecated historical domain: b00p.tech and www.b00p.tech; no DNS restoration is planned
- Social short link for TestFlight: https://every.band/testflight
- App Store release is pending. A working TestFlight invitation or a source commit does not prove a particular build is available to install.
- Price: $0 download with optional one-time Boop Full purchase; no subscription — see https://every.band/pricing.md
- Instagram: https://www.instagram.com/geteveryband/ (@geteveryband)
- LinkedIn: https://www.linkedin.com/company/boopcompanion/ (@boopcompanion)
- The website offers an optional email newsletter for EveryBand release, compatibility, and support updates.
- The website may use PostHog product analytics only after cookie consent. The iOS app does not use PostHog or any analytics SDK.
- EveryBand is not a medical device. Outputs may be approximate and are not for diagnosis or treatment.
- EveryBand is independent and is not affiliated with, endorsed by, or sponsored by WHOOP, Apple, or Bevel.
- WHOOP names are used only to state factual device compatibility.
- Direct Bluetooth integration covers WHOOP 4.0, WHOOP 5.0 and WHOOP MG, with model and firmware limits. Battery, firmware and supported history have been tested on all three models. Background imports have been observed on WHOOP 4.0 and MG; timing depends on iOS and Bluetooth range. Unrecognized history formats remain unavailable. MG ECG and WHOOP 4.0 temperature and oxygen calibration are not yet validated.
- Derived estimates are distinguished from decoded observations and carry EveryBand algorithm-version metadata where supported (revision depends on the installed build).

- Boop Full includes dedicated Sleep, Recovery, Strain, Journal, Fitness, and longer-term insights.
- Apple Health can be set up later. Local strap processing continues without Health export.
- TestFlight shows the currently available build and its device requirements.

## Supported / not supported

Direct strap scope:

- WHOOP 4.0 strap
- WHOOP 5.0 strap
- WHOOP MG strap
- Compatible iPhone with Bluetooth; Apple Health access is optional
- TestFlight invitation; available builds are shown by TestFlight

Not supported / out of scope:

- EveryBand account, EveryBand subscription, or EveryBand health-data cloud
- Medical diagnosis or treatment use
- Direct data handoff to third-party apps (for example Bevel); those apps may read Apple Health only if the user authorizes them separately
- App Store release (pending)
- Native watchOS app or continuous live Apple Watch stream

## How EveryBand fits (factual)

| Topic | Official wearable app path | EveryBand |
| --- | --- | --- |
| Primary job | Vendor platform experience | Independent on-device wellness insights, direct strap sync and optional Health export |
| EveryBand account | N/A | None |
| Processing | Vendor product stack | On the user's iPhone |
| Affiliation | Official vendor software | Independent; not affiliated with WHOOP |

After EveryBand saves and acknowledges history, it may trim that history from the strap; trimmed history can be unavailable to the official app. Users must acknowledge this during onboarding.

## Methods and interpretation

- The documented Recovery calculation compares local nightly RMSSD and resting heart rate with prior complete nights, uses available Sleep/context, and reduces early extremes as history builds. Missing required inputs keep it unavailable.
- The Sleep score combines available sufficiency, consistency, efficiency and high sleep stress components. Wrist sleep-stage estimates are not a diagnostic sleep study.
- Strain is an independent activity-load index and can exceed 100. It is not a percentage or WHOOP's scale.
- Stress is physiological context, not a measurement of emotion or anxiety.
- Energy Reserve is a composite wellness index, separate from estimated calorie expenditure.
- Strength logs record completed work; estimated progression is not a validated muscular-strain measurement. Journal associations are not causal effects.
- Source citations describe definitions/background and do not validate EveryBand's end-to-end pipeline.
- Comparisons are publisher-authored, dated and sourced; no accuracy winner, medical superiority or ranking outcome is asserted.

## FAQ

- Which models? Direct Bluetooth integration for WHOOP 4.0, WHOOP 5.0 and WHOOP MG, with model and firmware limits. Independent, not affiliated with WHOOP.
- Does EveryBand upload health data? No uploads to EveryBand-operated servers or advertising use. Processing is on device. Users control Health writes and file exports/sharing; Apple Health sync and device backup follow their Apple settings. Optional diagnostic exports may include original biometric bytes and device identifiers, shared only to a user-chosen destination.
- Can Apple Watch be used without a strap? Yes, through recorded Apple Health data in the current TestFlight beta; not a live Watch stream or watchOS app.
- Is it free? Free download with an optional one-time Boop Full purchase; no subscription. TestFlight purchases are free sandbox transactions and do not carry over to the App Store.
- Medical device? No. Not for diagnosis or treatment.
- Remove strap history? May trim acknowledged history after a successful save; can affect the official app.
