Oura says it typically takes 2–4 weeks of consistent wear to establish personal baselines. Keep the ring charged before bed, then review and correct activity detections rather than assuming every estimate is complete.
1. Check phone compatibility and set up the app
Oura’s app requirements are iOS 16 or later, or Android 11 or later with Google Play services, plus Bluetooth 5.0. Availability of some features depends on country. Follow Oura’s setup instructions and the prompts in the app to connect the ring, sign in or create an account, complete the requested profile details, and sync. The exact screens can vary, so follow the current in-app prompts rather than relying on a fixed sequence.

2. Choose a good fit and orient Ring 4 correctly
Use the Ring 4 sizing guidance rather than assuming a size from another ring or an older Oura model. The ring should feel snug but comfortable, and Oura recommends the index, middle, or ring finger for signal quality. Wear Ring 4 with its dimple on the palm side of your finger; this places its sensors against the palm side. Oura’s Ring 4 fit and orientation guidance is specific to this generation, so do not substitute instructions for a different model.
3. Wear it consistently while your baseline develops
Oura recommends wearing the ring around the clock for the most useful personalization. At first, the app relies on population averages; Oura says personal baselines usually take 2–4 weeks of consistent wear to establish. Gaps in wear mean less data for the app to interpret. These steps support more consistent insights, but they do not guarantee clinical accuracy, correct sleep-stage estimates, or a particular score.

4. Keep enough charge for overnight sleep data
Oura says the ring needs at least 30% battery before bed to provide sleep data the next morning. Check the battery in the app before settling in for the night and charge beforehand if needed. Oura lists a typical 5–8 day battery life for Ring 4, but actual runtime varies with ring size, settings, features, activity, battery age, and use; treat the in-app battery display as the practical guide.
The Ring 4 charger and Ring 4 charging case are both size-specific charging options. The case is portable and supports multiple charges, while the corded charger is a stationary accessory. Neither is a necessary upgrade if you already have the included charger.

5. Use sleep guidance as context, not a score target
Bedtime Guidance
Bedtime Guidance appears after two weeks of consistent data and is calculated automatically from recent sleep patterns and wake times. It suggests a window for going to bed; it is not a target you must hit to earn a better score. Oura says missing the suggested window does not directly affect Sleep or Readiness Scores. Read Oura’s Bedtime Guidance explanation for details.

Body Clock and chronotype
Body Clock guidance is different: it reflects a more stable chronotype and circadian-oriented pattern, rather than just recent wake times and sleep. Use it as broader context for your schedule, not as a substitute for the shorter-term Bedtime Guidance.

Correcting a recorded sleep period
If a sleep period’s timing is recorded incorrectly, you can adjust bedtime or wake time in the Sleep detail view. The edit is limited: you can shorten a sleep period, not lengthen it, and you cannot change data more than three days old. Edits affect that day’s Sleep and Readiness insights.

Confirm or correct automatic detections
Automatic Activity Detection proposes an activity type, time, duration, and intensity for you to confirm, edit, or dismiss. Review the suggestions instead of treating them as a complete activity log: detection is an estimate, and some activities may be missed or misclassified. Oura explains how to manage detected activities.

Add activities manually when needed
If an activity did not appear, add it manually. Manually entered activities take precedence over imported activities and automatic detections, so use the entry that best reflects what you actually did.
Enable location for supported route details
If you want route, distance, speed, or pace for supported activities, allow location access. Oura says the app must be open and running in the background before the activity begins for location tracking to work. Location access is optional; enable it only if those route-related details matter to you.

Optional setting: bedtime notifications
If a reminder would help you follow a regular schedule, enable bedtime notifications in the app and allow the relevant phone notification permission. Notifications are optional; they do not change the ring’s measurements. Oura’s guidance for overnight sleep data is to have at least 30% charge before bed.
