We move fast,
and in the open.

Faster, smoother, more languages, and a big pile of fixes

• Faster, with a lot of fixes. The lag after importing Apple Health data is gone, Today opens on today again after an update, the active-workout stats no longer get cut off, and the alarm page reads correctly.
• Your imports go further. Workouts now come in from Apple Health, Health Connect days that arrived as an import now earn their own Charge and Rest, and Back up to a folder works on iPhone.
• Now in Spanish and Italian. Two more full translations, with more to come.
• Sleep, navigation and devices. A single night is no longer split into a separate nap, the More tab remembers which sections you left open, and your strap firmware version now shows on the Devices screen.

Local Oura ring support: use your Oura ring with no Oura app

• Local Oura ring support (beta). NOOP can now read an Oura ring directly over Bluetooth, fully on-device, so you can use the ring with no Oura app, no account and no cloud. It reads heart rate, HRV, SpO2, skin temperature and sleep stages off the ring and runs NOOP's own Charge and Rest scoring, not Oura's. Works on Oura Ring 3, 4 and 5.
• How setup works. Pairing factory-resets the ring and adopts it locally, which is recoverable: if NOOP cannot take it over, you just re-pair it in the Oura app. This is early beta, so there is also an Advanced bring-your-own-key path and a file-import fallback.

A calmer Today, your Charge explained, and new HRV science under the hood

• A simpler Today. The dashboard had got busy, so we calmed it down: one clean read at the top, the daily synthesis folds into a single line you can expand, and the metric cards line up evenly.
• See exactly what shaped your Charge. Tap your Charge to see which signals moved it and by how much (HRV, resting heart rate, sleep, respiration, skin temperature), each with a plain-English note. A new "How Charge is calculated" link explains the method itself.
• New on-device measures from your heart-rate rhythm. The Stress screen now also shows frequency-domain HRV (your LF/HF autonomic balance) and a Baevsky stress index, both computed locally from the day's beat-to-beat data.
• Test Centre is one tap away. The diagnostics and bug-report hub moved out of Settings and into the More tab and the Mac sidebar, so reporting something takes seconds.

The Test Centre: help us fix YOUR specific problem

• New: a Test Centre. Every diagnostic and logging control now lives in one place, and you can opt into a test mode for the exact thing that is not working: Sleep, Battery, your scores, Connection and sync, Workouts, Steps, Imports, or smoothness. Turn it on, use NOOP as normal, then export a clean report in one tap.
• Your data stays yours. Every test mode runs on your device, the exported report is redacted and you review it before you share it, and nothing ever uploads on its own.

Board Sweep: battery days-left, browse past weeks, breathing cues, and a pile of fixes

• New: "~X days left" on your strap battery. NOOP watches how fast the band is discharging and tells you roughly how many days are left, right on the Today battery badge. All on-device.
• New: browse previous weeks in Trends. Flick back through your Weekly Trends history week by week, instead of only seeing the current one.
• New: breathing cues. An optional audio pacer for the breathing exercise, with a ring that breathes along with you. It stays quiet when your phone is on silent.
• A stack of connection and sleep fixes. Straps that said "connected" but sent no data now connect properly, and sleep on the WHOOP 5 and MG no longer over-counts time awake.

Everything: a whole new look, hydration, automatic workout detection, and smarter sleep

• A whole new look. NOOP has been redesigned from the ground up: flat, clean colour rings, a day-cycle scene that moves with your day, and a Today screen you can customise. The same fresh look lands on iPhone, Mac and Android together.
• New: Hydration tracking. Opt in and log your water through the day with a simple tap, set a daily target, and see how you are doing at a glance. Off by default.
• New: Automatic workout detection. Opt in and NOOP spots a likely workout from your heart rate and motion and offers it for a one-tap add. Nothing is logged without you confirming it.
• Experimental: Sleep Staging V2. A new on-device sleep stager you can switch on to try a sharper deep/REM/light breakdown, clearly labelled experimental while we prove it against real nights.

See Everything: the Deep Timeline, a sleep movement graph, and a big board-clear

• See everything, second by second: the new Deep Timeline. Open a metric and pinch or scroll to zoom from a whole day right down to per-second detail: heart rate, HRV, SpO2, skin temperature, respiration and movement, all at full resolution, all on your device.
• A movement graph for your sleep. The Sleep screen now draws a restlessness trace under your hypnogram, so you can see how much you stirred through the night.
• WHOOP 5.0 is honest about sync now. A connected 5.0 streaming live heart rate but no history says so plainly, and stops the battery-draining reconnect loop while it waits.
• Spot HRV will not fake it. An on-demand HRV reading now refuses to give a number when too much of the capture was noise, instead of showing you a shaky one.

A big one: smarter sleep, naps, more devices, and a load of fixes

• Sleep got smarter and more honest. A night split by a wake-up is now counted in full instead of just one fragment, a bad-clock strap can no longer pass off a 12-hour block as one night, and your own hand-edits to a night now win over an imported value.
• Naps, spotted on your device. Opt in and NOOP notices a likely nap from your motion and offers it for a one-tap add. Nothing is logged automatically, and it never touches your real sleep scores.
• More at a glance. A new 2x2 Android home-screen widget shows Charge, Effort and Rest together, plus optional morning-recap and post-workout notifications, both off by default and no AI involved.

NOOP grows up: it is not just for WHOOP anymore

• Your WHOOP is no longer the only thing that works. NOOP now reads standard Bluetooth chest straps and arm bands for live heart rate and HRV, connects to gym machines over the standard FTMS profile, and reads standard running and cycling sensors during a workout.
• Bring your history with you, fully offline. Import your own data export from Oura, Fitbit or Garmin and NOOP pulls in sleep, resting heart rate, HRV and steps. It never talks to their cloud, and your NOOP scores are recomputed from the raw signals, never copied. GPX, TCX and FIT workout files import too.
• Broadcast your heart rate out. Turn on Broadcast in Data Sources and NOOP re-shares your strap's heart rate as a standard Bluetooth HR sensor, so a treadmill, Zwift or Peloton can read it. Local Bluetooth only.

v5: the raw-signal release, NOOP reads the signal, on your device, free

• The big idea. Everyone else shows you a score their cloud computed, behind a subscription. NOOP reads your strap's raw signals (beat-to-beat timing, red/IR PPG, motion, skin temperature) and does all the maths on your own device, free and offline.
• Haptic biofeedback, the strap that breathes you down. Your wrist motor can pace your breathing with the screen off. Find your personal calm pace, then breathe to the buzz, or tap "Calm me · 3 min" mid-stress for a felt metronome just below your heart rate.
• What Moves You. A ranked, lag-aware read of what actually moves your recovery, from your own journal and outcomes, not population averages.
• Lab Book. Your own private logbook for bloods, blood pressure or scan values, lined up against a wearable signal. It is a notebook, not a medical service, and it all stays on your device.
