Roadmap

Where live planning happens

Up-to-date plans and what's shipping next live in the Releases and the Discord. This page captures the long-term direction shared across the project.

Principles

These guide what we build and what we say no to.

  • Privacy-first: your health data stays on your device by default.
  • Subscription-free: every feature, for everyone, no paywalls.
  • Open & transparent: documented metrics and an auditable coach, no black boxes.
  • Hardware freedom: cheap devices, your data, and eventually your own firmware.
  • Cross-platform: one direction shared across iOS and Android.

Direction

More wearables, more freedom

  • Open BLE standards: heart rate (+ HRV), blood pressure, temperature, weight, and glucose. Supporting the standards adds chest straps, BP cuffs, and scales with little per-device work.
  • Reverse-engineered protocols: more rings (Ultrahuman, RingConn, …) and bands/watches (Amazfit/Zepp, Xiaomi) beyond today's 56ff and Colmi families.
  • Device-driver SDK: let contributors add a wearable without touching the core.

Own the hardware

  • Reverse-engineer ring firmware and the over-the-air update path.
  • Load custom firmware safely: higher sampling rates, longer battery, and access the stock app blocks.
  • Unlock raw PPG and accelerometer signals: the basis for everything intelligent.

On-device intelligence

  • Local LLM coach: run against an on-device model: no API key, no network, full privacy.
  • Automatic workout detection: recognize runs, rides, and walks with no manual start.
  • Proactive insights: weekly trends and call-outs the coach surfaces for you.
  • Auditable coach: show which tools the coach called and what data it read.
  • Personal baselines: learn what's normal for you and flag meaningful changes.

Metrics you can trust

  • Performance & recovery: readiness, training/cardio load, HRV and resting-HR trends, VO₂max.
  • Health signals: illness early-warning from shifts in skin temperature, resting heart rate, and respiration.
  • Cycle tracking: menstrual cycle and BBT from skin temperature, computed on-device.
  • Energy balance: calorie-burn estimation paired with food logging via an open food database.

Your data, your way

  • Optional sync: Apple Health, Google Health Connect, Strava, Garmin; useful for export and for cross-checking your readings.
  • Self-hosted export: Home Assistant, InfluxDB/Grafana, MQTT, and open formats (FIT, GPX, CSV, JSON).
  • Ownership by default: your data is portable and never required to leave the device.

Everywhere you are

  • Multiple wearables at once: aggregate several devices into one picture.
  • watchOS companion: glanceable data, or use a watch as another sensor.
  • Web app: a third client alongside iOS and Android.

Cross-platform parity

Because the iOS and Android ports share the same protocol work, a big part of the roadmap is simply bringing the two ports to feature parity. The low-level protocol, calibration, and connection reliability are now on both. iOS leads on the AI Coach (multiple providers, on-device model, multimodal input), while Android still leads on a few vitals detail screens and a couple of Colmi-specific decodes.

See iOS vs Android for the current gap list. Much of it is fair game for contributors who want a well-scoped first task.

Want to help?

  • Skim the open issues, especially anything tagged good first issue.
  • Propose or claim work in the Discord. Coordinate anything that should land on both platforms.
  • See Contributing to get set up.
