The '''''trend view''''' of the body temperature is a bit more complicated. Oura states that "the trend view displays a weighted average of how your body temperature varies from your baseline based on a three-day window" and that "days closed to the current date will have more of an impact on your readings"<ref>https://support.ouraring.com/hc/en-us/articles/360055983614-Trends</ref>. Oura does not disclose the details of how the weighting of records is done and as such it is not possible to really understand or recreate how the company arrives at these values. One observation is that the ''trend'' values tend to be slightly biased towards positive values, probably as the distribution of possible body temperatures is not fully normally distributed, but rather censored on the lower end<ref>https://www.reddit.com/r/ouraring/comments/v6zirx/how_is_temp_trend_always_positive/ibl6vy1/</ref>.

==== Use for menstrual cycle tracking ====
The rings of the 3rd generation include an Oura internal beta-test for cycle tracking. Furthermore, since mid-2022 the ''[[Natural Cycles]]'' app – a cycle tracking app that's cleared for use as birth control – can use the temperature data from the ring as main input to predict fertile time windows<ref>https://www.naturalcycles.com/oura</ref>.

As for most wearables, there is unfortunately no (easy) way to access all raw data from the device. But Oura offers a way to [https://cloud.ouraring.com/profile download at least all of your calculated metrics from the ''Oura Cloud'' web interface]. Beyond this, they also offer an API to automate access to Oura data in third party tools. An example implementation is the [https://oura.openhumans.org/ ''Oura'' integration into Open Humans], which automatically fetches the latest data at multiple times throughout the day.

In January 2022, Oura announced a version 2.0 of their API for exporting data<ref>https://api.ouraring.com/v2/docs</ref>. This new API is under development and so far only provides access to more detailed activity data (such as intra-day heart rate) but not to any readiness and sleep information and so far there is no timeline when these other metrics are added to the new API. Oura also announced that the old version 1.0 of the API will be around for at least a year before being shut down.

For now the version 1.0 of the API still works and is scheduled to be sunset at some unspecified time in early 2023<ref>https://cloud.ouraring.com/docs</ref>.
