BART is partnering with Uber Transit to fully integrate seamless end-to-end journey planning and payment all within the BART app. Riders will no longer need to use multiple apps to plan their BART trip and plan and pay for an Uber ride. Everything can be done without leaving the BART app, and the total trip time will be displayed, making things faster and easier for users.
The Readiness tab on the app tracks things like your resting heart rate, body temperature, and respiratory rate. I will note that the ring, which comes with its own charging port, has a fairly generous battery life, but it does need to be regularly charged in order to track daily metrics. I typically have to power it up once every five days or so.
