Your WHOOP data, on your own devices, with a coach that remembers.
Today, the redesigned Training Load, and Sleep — all computed on the device you're holding
A WHOOP strap is remarkable hardware locked to WHOOP's own app, subscription and cloud. NOOP AI talks to the strap directly over Bluetooth, computes Charge (recovery), Effort (strain), Rest, sleep staging, HRV and training load on your iPhone or Mac, and keeps every number there. No WHOOP account. No NOOP account either — there's nothing to sign into and nowhere to sign in to.
On top of that foundation, this fork adds a coach that can actually look at your data: an on-device semantic memory of what you've told it, 26 tools it can use only with your consent, and goal tracking that never quietly rewrites your plan for you. Bring your own API key (or run a fully local model) and the coach reads your Charge, sleep and training history to have an informed conversation — or don't configure one at all, and NOOP is a complete recovery and training app without it.
It ships the way it's built: an unsigned iOS build you sideload with your own Apple ID, and a Mac app you build or download directly. No App Store review, no App Store account, no telemetry reporting any of this back.

Three presentations of the same day — Classic rings, a Liquid Design glass treatment, or a dense Overview grid — pick whichever reads best to you in Settings › Appearance. Recent workouts, a live beat-by-beat heart rate card while the strap is connected, and HRV / resting heart rate / respiratory rate sit right below the rings, with a proposed session and the coach's take on the day when you want it. |
|
|
A reconstructed hypnogram for last night, stepping back through every earlier night you've recorded. Stage minutes, efficiency, a "vs typical" tile grid for performance, consistency, hours against your personal need, and sleep debt that decays instead of compounding forever. A "may be incomplete" badge now reflects how short the night actually was, not just thin motion data. |
|
Chronic load (fitness), acute load (fatigue) and the balance between them, as a proper long-horizon chart — rebuilt this release on one shared design kit with dedicated colour lanes so Training Load, Cardio and Strength read consistently at a glance. Cardiovascular load, strength load and whole-session load stay in their own units; nothing here invents an "× usual" claim before there's enough history to back it. |
|
Log sets directly in NOOP: routines, supersets, unilateral work, RIR, rest timers and plate loading, with a body-based muscle picker over one shared exercise catalogue. Balance, Fatigue and Strength views share one detailed muscle map so working-set distribution, remaining stimulus and e1RM trends all read off the same taxonomy. FitNotes, Strong and Hevy imports join the same history without duplicating overlapping sets. |
|
Live cardio recording continues while NOOP is backgrounded, the running session shows on the Lock Screen and in the Dynamic Island, and starting a workout from Live, Workouts or a Quick Action always resumes the same session — no more losing track of which screen "owns" the workout you're mid-way through. |
|
Weight history and trends get their own card. Daily energy expenditure blends NEAT, a personal forecast curve and active-only calibration, is always source-aware (it says whether a number came from WHOOP, Apple Health, or an estimate), and offers an opt-in Apple Watch calibration step rather than silently trusting one device over another. |
|
Bring your own API key (Anthropic, OpenAI, Gemini, OpenRouter or a custom OpenAI-compatible endpoint) or run a fully local model. The coach reads through 26 individually consent-gated tools — biometrics, sleep, workouts, stress, energy, goals — and can propose a session or a goal setup, never silently apply one. An on-device semantic memory (Nomic embeddings, nothing sent to a server) lets it recall what you've told it without re-explaining yourself every time. |
|
Up to five active goals — run, consistency, sleep, strength, weight or a custom one — checked for feasibility before they become a plan. The Journey page shows a measured percentage only when a real baseline and target exist; otherwise it says plainly what's actually known. Milestones are facts (a real recovery uptrend, your longest run), never a streak counter that punishes a sick day. |
|
Direct Bluetooth to a WHOOP 4.0 or 5.0/MG, a WHOOP CSV export, Apple Health, FitNotes/Strong/Hevy
strength imports, GPX/TCX/FIT routes, and an experimental Oura ring pairing — all parsed and
merged locally. A |
|
Home Screen and Lock Screen widgets for the recovery ring, live heart rate and the coach's morning brief; a watchOS companion with complications; and — new this release — a Sync Strap Shortcut, a keep-screen-on option while syncing, and a sync Live Activity for the Lock Screen and Dynamic Island. |
NOOP AI is offline-first. Your strap data, database, scores, history, goals, coach memory and plans stay on your device. The optional AI Coach contacts only the provider you configure, only when you ask it to; an experimental Oura history import and the manual/at-most-daily public-release check are the only other network paths, and neither uploads raw sensor streams or gives NOOP a server or account.

The iOS build is an unsigned IPA on purpose. Add the source below in AltStore or SideStore, and the sideloader signs the app locally with the Apple ID you choose — NOOP AI never receives your Apple ID or a signing certificate.

NOOP-ios-unsigned-v11.8.1-dx.ipafrom the 11.8.1 release. It includes the Home/Lock-Screen widgets, which AltStore/SideStore sign along with the app. - Need the Apple Watch app? The same release also carries
NOOP-ios-full-unsigned-v11.8.1-dx.ipa, which adds the Watch app and complication. It wants a signer or paid Developer team that can provision all of it together — sideloaders install an embedded watchOS bundle unreliably, and a failure there costs you the whole install, which is why the AltStore source stays on the watch-less IPA.
See the iOS install guide for the free-Apple-ID limits, widget notes, and build-from-source instructions.
Download NOOP-macos-v11.8.1-dx.zip from the
11.8.1 release, unzip it, then
right-click → Open the first time (it is ad-hoc signed, not notarised, so a double-click is
blocked).
The bundle is universal — Apple Silicon and Intel. Ad-hoc signing is what lets macOS bind the Bluetooth permission to the app; after an update macOS may ask you to re-approve Bluetooth, because the code identity changes with every build.
You need a Mac with Xcode 26+ and XcodeGen.

| iOS / iPadOS | 11.8.1 | AltStore, SideStore, or build from source |

Core logic lives in cross-platform Swift packages, with each Apple platform as a thin app layer over them:
| Layer | What lives here |
|---|---|
| Protocol | BLE frame parsing, CRC, command/event decoding — no CoreBluetooth, builds standalone |
| Storage | GRDB/SQLite persistence, migrations, streams |
| Analytics | HRV, recovery, strain, sleep, training load and correlation math — database-free, pure functions |
| Coach | Chat shell + providers (shared lineage with ryanbr/noop), extended with semantic memory, tool-calling and goal tracking (fork-only) |
| Import | WHOOP CSV, Apple Health, FitNotes/Strong/Hevy strength imports |
| Design system | SwiftUI palette, components and charts shared by every screen |
ryanbr/noop's protocol reverse-engineering, analytics groundwork and design system are the base
this fork builds on. Where the two diverge — Apple-only distribution, the extended coach, native
training — is kept in its own layer so upstream fixes can keep merging in cleanly.

NOOP AI is a personal fork of ryanbr/noop. The upstream project deserves credit for the protocol, analytics and design-system foundations, and continues to develop its own coach in parallel; this fork develops the extended coach (memory, tools, goals), native training and Apple-first sideload distribution independently. It is an unofficial, non-commercial interoperability project and is not affiliated with WHOOP.
NOOP AI is not a medical device. Its health and training values are on-device estimates, not clinical advice or diagnosis. Use it as a personal tool and consult a qualified professional for medical decisions.
