Use your pulse-ox data to optimise your sleep.
Sync your Wellue oximeter and see exactly how your blood oxygen, heart rate and breathing behave overnight — then learn which habits, timing and routines actually improve your sleep, and your long-term health and wellbeing.
No app install. Works in Chrome & Edge via Web Bluetooth.
Everything you need to find what improves your sleep.
Measure your nights, understand the metrics that track sleep quality, and pinpoint the habits, timing and routines that actually move them.
One-tap Bluetooth sync
Pair the Checkme O2 Max straight from your browser and pull every stored session over BLE — no cables, no vendor app. Already have exports? Drop the official CSVs in and they slot right alongside.
Overnight analysis
Automatic ODI-3% & ODI-4%, desaturation burden, time-below-90/88% and SpO₂ nadir — with severity badges that flag the dips that matter.
Heart-rate & CVHR
Mean, range and variability plus Cyclic Variation of Heart Rate — the autonomic signature of obstructive apnea — and HR-to-SpO₂ coupling.
Tag your nights
Label recordings with events like “Large dinner” or “Alcohol”, then see how each one shifts your ODI, heart rate and CVHR across every night. New tags can auto-apply to future sessions.
Log any measure
Track a nightly number for anything — energy, weight, room temperature, alcohol units — and each one is correlated against your ODI, heart rate and CVHR so you can see what actually moves them.
Timing & duration insights
See how your bedtime, wake time and total sleep duration correlate with your metrics — a clear scatter plus a plain-language takeaway for each.
Compare nights
Pick multiple sessions across any day and line their metrics up side by side to spot trends, outliers and what’s improving.
Day-by-day history
Every recording charts SpO₂ and heart rate second by second, with drag-to-zoom on any window and an ODI & CVHR trend that shows how the night unfolded. Sessions group into a clean daily carousel so weeks of nights stay one swipe apart.
Private by default
Your readings are scoped to your account and stored on your own database — nothing is shared or sold, and you can delete any session anytime.
From wrist to better sleep in three steps.
No installs, no manual exports. Connect once and your history is ready to explore.
