What Does RingConn Track? Complete Feature Guide (Gen 2 & Gen 3)
Short answer: RingConn tracks heart rate, HRV, SpO2, breathing rate, skin temperature, sleep stages, sleep score, stress score, steps, and calories — all without a subscription. Gen 3 adds blood pressure trend monitoring. It does not track GPS, ECG, or menstrual cycle.

Health metrics in detail
Heart rate
RingConn monitors heart rate continuously 24/7 using green LED PPG sensors. In the app you see:
- Resting heart rate (daily average during low-activity periods)
- Overnight heart rate graph (sleep monitoring)
- Real-time heart rate (check on demand in app)
- High/low heart rate alerts
Accuracy: RingConn heart rate accuracy is ±2-3 bpm at rest and ±5-7 bpm during moderate exercise.
HRV (Heart Rate Variability)
HRV is measured overnight during deep sleep, when external factors are minimized. This is the most accurate measurement window.
- RMSSD method (standard for wearables)
- Shows overnight average
- Tracks trend over days/weeks
- Powers the Stress Score
SpO2 (Blood Oxygen)
Continuous overnight measurement using red/infrared LED sensors.
- Shows overnight SpO2 average
- Flags drops below 94% (configurable threshold)
- Relevant for sleep apnea screening

Breathing Rate
Calculated from heart rate patterns (respiratory sinus arrhythmia) during sleep.
- Average overnight breaths per minute
- Normal range: 12-20 BPM for adults
- Deviation alerts
Skin Temperature
Tracks overnight temperature deviation from your personal baseline.
- Shows nightly temperature relative to your average
- Useful for illness detection (fever shows up early)
- Correlates with menstrual cycle phases
Blood Pressure Trends (Gen 3 only)
Overnight measurement using pulse wave analysis.
- Shows directional trends (rising, falling, stable)
- Not absolute readings (not 120/80 format)
- Measured during sleep only
Sleep tracking metrics
RingConn’s sleep tracking is the core strength of the device:
- Sleep stages: Light sleep, Deep sleep, REM sleep, Awake
- Sleep duration: Total time, time in each stage
- Sleep score: Composite 0-100 score
- Sleep latency: Time to fall asleep
- Wake episodes: Number and duration of nighttime awakenings
- Breathing rate: Average overnight
- SpO2: Overnight average and minimum
- Heart rate: Overnight graph

Fitness and activity metrics
RingConn is primarily a health monitor, not a fitness tracker. What it does:
- Steps: Counted via accelerometer throughout the day
- Calories: Estimated based on steps, heart rate, weight, age
- Activity detection: Automatically recognizes walking, running, workouts (no GPS or pace data)
- Active minutes: Time spent in elevated heart rate zones
What it doesn’t do: GPS tracking, swim lap counting, specific sport modes, real-time workout coaching.
RingConn vs what other rings track
| Metric | RingConn Gen 3 | Oura Ring 5 | Samsung Galaxy Ring |
|---|---|---|---|
| Heart rate 24/7 | ✅ | ✅ | ✅ |
| HRV | ✅ | ✅ | ✅ |
| SpO2 | ✅ | ✅ | ✅ |
| Breathing rate | ✅ | ✅ | ❌ |
| Temperature | ✅ | ✅ | ✅ |
| Blood pressure | ✅ | ❌ | ❌ |
| Sleep stages | ✅ | ✅ (better) | ✅ |
| Period tracking | ❌ | ✅ | ✅ |
| ECG | ❌ | ❌ | ❌ |
| Subscription | None | $6/month | None |
The bottom line
RingConn tracks more health metrics per dollar than any other smart ring (no subscription). Gen 3’s blood pressure monitoring is unique in the category. Where it falls short is lifestyle/fitness features: no GPS, no workout modes, no period tracking, no ECG.
If you want comprehensive passive health monitoring at the lowest long-term cost, RingConn covers everything that matters. If you need dedicated period tracking or advanced fitness features, Oura Ring 5 covers more ground.
