Summary: Device has capacity to transmit data, and ipad has plenty of capacity to record. But after purchase, discovered the app is lame, and will not record more than few minutes. Not ready for prime time. But as one comment stated, "that would be cool". Duh.
Summary: It took me all of 5 minutes to unpack and set up my Oximeter. Bluetooth connected to my iPhone and iPad with no effort, and as I use both I found that all my data is on both. No effort on my part, they keep both up to date. This has been as effortless a purchase as I would want. The Oximeter is very well built and looks very good.
