very accurate and easy to use

Yes you do need a cable / oximeter device with the app…. well.. its more like the app goes with device not the other way around.

I purchased a standalone oximeter on amazon along with the Masimo device to bring with me on a trip to Mt. Everest. As I was intending to climb without altitude medication accuracy was important. Both devices were nearly exact each time used, however I was thankful for the ability to track changes in my pulse/ oxygen levels with the app.

Its very clear and easy to use. One improvement would be ability to create multiple users to store individual consecutive entries … as well as the ability to store more data even for one person ( think it caps at 10 days? )

overall pretty awesome, and highly recommended for climbers/ athletes looking to monitor pulse and/ or blood oxygen.
