See Ringlo turn a cheap smart ring into sleep stages, HRV, SpO2, and a daily readiness score.
Daily readiness at a glance.
Sleep stages on a timeline, one lane per stage.
Calibrate against a real cuff. Numbers track closer to truth.
Your latest HRV, with recent readings and history.
All the health insights your ring can measure, in one beautiful dashboard.
24/7 monitoring with resting HR trends and customizable high/low alerts.
Pair a real cuff reading with the ring's estimate. The app calibrates from there, so your numbers track closer to a cuff. Not medical-grade, but honest.
Deep, light, REM and awake on one timeline, a lane per stage. Distinct stage colors, nightly score, weekly trends.
On-demand SpO2 readings and overnight blood oxygen tracking.
Heart rate variability and stress insights to guide your recovery.
Daily 0–100 score combining sleep, HRV, and resting HR.
Steps, calories, distance, and workouts you start from the home screen.
Pick the colour palette you want across the app, choose which three rings sit at the top of your home screen, and choose the four Today’s Vitals tiles underneath them.
Start a workout from the home screen and it lands in a section of its own, with your week’s sessions and how they compare.
When a nap is detected, Ringlo asks whether it belongs to last night’s sleep or stands on its own - and remembers your answer if you’d rather not be asked again.
Quiet Mode runs without a persistent notification, the ring measures autonomously. Days of ring battery, not hours.
Sync your ring data to Apple Health on iOS or Health Connect on Android. One-way, private, optional.
Ringlo has been redesigned from the ground up. Steps, heart rate, blood pressure, SpO2, sleep, recovery, workouts, and shared health with friends - one tap away.
Pair once. Track forever.
Free on App Store and Google Play. No credit card to start.
Turn on Bluetooth, open Ringlo, and tap Pair. Takes 30 seconds.
Wear your ring 24/7. Pick Quiet Mode on first launch for best battery, or Always-On for live data streaming.

Ringlo works with smart rings that use the YCBT protocol - the rings that ship with the SmartHealth or YCBT Life app. The DL110 (Actions Semiconductor ATS8266 chip) is a YCBT ring. If your ring came with one of those apps, it's almost certainly compatible - or just open Ringlo and tap scan to verify in ~10 seconds.
Open Ringlo, go through onboarding, and tap "Pair Ring." Make sure your ring is charged and nearby - the app scans for compatible rings automatically.
No. Ringlo is a wellness app. All readings are estimates for informational purposes only - not intended to diagnose, treat, or prevent any medical condition. Always consult a healthcare professional for medical decisions.
Manage your subscription through the App Store (iOS) or Google Play Store (Android). Go to your device's subscription settings to cancel or modify.
Open the app, go to the "You" tab, scroll to the bottom, and tap "Delete Account." This permanently removes your account and all associated data.
Yes. Your data is stored securely in Firebase and never sold to third parties. You can export to JSON or delete your account anytime.
Yes, on Colmi's QRing / Colmi Fit (BlueX) firmware. You get heart rate, SpO2, sleep, and steps; blood pressure isn't available on that path. The R10 is verified on our own ring; R02, R03, and R06 rings have connected for Ringlo users, and they need Bluetooth bonding. Download the free trial and tap scan to confirm in ~10 seconds.
Yes. As of version 1.33, Ringlo can sync your ring data to Apple Health (iOS) or Health Connect (Android). Enable it in Settings, Health Integration. Writes heart rate, blood pressure, blood oxygen, sleep stages, steps, and calories. One-way only, Ringlo does not read from your health platform. JSON export remains available from Settings as well.
Quiet Mode is the default sync mode. It runs Ringlo without a persistent notification and lets the ring measure autonomously, which gives you days of ring battery instead of hours. Always-On mode is available if you want real-time streaming, and Sport workouts auto-switch to live data while you exercise.
Yes. Tap the + button on the Sleep card to add a manual entry. Manual entries are flagged in your history and merge with ring data on the same night.
Yes. The ring connects to your phone via Bluetooth. Ringlo caches data locally so you can check your stats offline; syncs happen opportunistically in the background.
Several days on a charge, depending on the ring and how often it measures. Ringlo notifies you when battery drops below 20% and again when charging completes.
Not a replacement for a premium Oura experience, but if you're pairing a $30 ring, you get most of the daily tracking value - readiness score, sleep staging, HR, SpO2, HRV - at a fraction of the subscription cost. See our 6-month head-to-head comparison.
We're planning a one-time lifetime option. For now, subscriptions are $3.99/month or $29.99/year with a 14-day free trial.
Yes. One subscription covers both platforms when you sign in with the same account.
