cindy
Cindy is an open-source AI agent that runs locally on your machine, integrates multiple AI harnesses and models, and provides memory, skills, and automation to perform real work in your projects and apps.
noop
NOOP is an offline, account-free companion app that pairs directly with WHOOP 4.0/5.0 straps via Bluetooth, stores all biometric data locally in SQLite, and computes recovery, strain, HRV, and sleep on-device using transparent, documented algorithms.

FR-AI / ANALYSISWhy it is worth attention
It is a rare fully local alternative to the official WHOOP cloud, built entirely on open-source, inspectable code with no server, telemetry, or account requirements, and it preserves accessibility after the original project was discontinued.
Who it is for
- WHOOP strap owners who want to own their biometric data without uploading to a cloud
- Privacy-conscious individuals who prefer offline health analytics
- Developers interested in BLE protocol documentation and on-device scoring algorithms
- Athletes and coaches seeking transparent training-load and recovery metrics
Use cases
- Track daily recovery, strain, sleep, and HRV entirely offline without a WHOOP subscription
- Import historical WHOOP CSV or Apple Health exports to centralize personal biometric history
- Use the on-device AI Coach (with optional local model) to ask plain-language questions about your data
- Generate shareable PDF reports of trends for a doctor or coach
Strengths
- Fully offline — no network, no account, no telemetry; all data stays on your device
- Open-source and inspectable: every algorithm is documented and references published scientific methods
- Cross-platform: macOS, Android, and iOS with consistent scoring across all platforms
- Preservation mirror ensures continued availability of source and builds after original project disappeared
Considerations
- Unsigned builds require sideloading on iOS and macOS (no notarization, no App Store), which may confuse non-technical users
- WHOOP 5.0/MG support is experimental — many deep metrics (sleep stages, SpO₂, skin temperature) are incomplete or unreliable
- Project is not actively maintained; updates are not promised and community depends on the continuity mirror
README quick start
Project status. The original NOOP project used to live at
github.com/NoopApp/noop, but that repository has been deleted and the original developer appears to have discontinued the project. This repository preserves the recovered source code and release artifacts for people who still rely on NOOP. I am hosting this as a continuity mirror until the original developer brings the project back. I am not promising updates at this time.To WHOOP: you can request archival of this repository at any moment by creating an issue. I am not here to deal with any hassle around it.

The all-new Liquid Metal look: living liquid scores, a sky that moves with your day, rebuilt on every screen. The same Today on iPhone and Android, and a metric’s own trend. One design across iPhone, Android & Mac.
Project Continuity
NOOP remains account-free, local-first software. This repository is a preservation mirror of the latest recovered source and artifacts after the original project disappeared.
Updates are not promised right now. The immediate goal is to keep the codebase and usable builds available until the original developer restores the project or a new maintenance plan exists.
