Yes, but [edited and upgraded to 4½ stars 7/14/2026]

4-star rating edited 7/14/2026: Gives accurate readings, and the first time attempted a BT connection worked and gave results on phone using the Beyond Oximeter App, but; after the first time, it would connect, but no data would be sent to phone like before. [7/14/2026 edit: I later learned by trial and error that although my settings for the app stated there were no restrictions, the app wants the location to be precise, not approximate to send data to the app.] The 500B-B pulse oximeter does not show up on the phone connected devices list, possibly because it connects to BT from the app (Beyond Oximeter). Instructions assume you will research medical implications of displayed data, which is OK, but also don't define terms used or what displays shown represent. [7/14/2026 edit: Device description on website does not positively say whether or not this model had a rotatable screen (it does not), except by no mention of a rotatable screen in the description. A comparison screen that showed this would be helpful, especially since there are so many models at so many price points, the differences between which are not obvious.]
