The Pulse Oximetry device isn’t bad for the price. It tracks a bit off compared to medical grade but it’s close enough. The whole register email and it’s sent to spam and you verify with a sketchy IP only Chinese web address makes one wonder. Wish the Health App could import or take the data to track. Would love to deep six the app.

This App works fine!!! Takes a little patience but it's worth the time. First, this is the App you want for the M70C Pulse Oximeter. When you first open the App, go to the "Registered" block and click it. It shouldn't have the "ed" at the end of the word and it would be less confusing!! The App will open up and you can Register. It will e-mail you and when you open that e-mail, it appears to "activate" your Account. You then go in and enter your data, weight, height etc. OR NOT since it doesn't use this data for any calculations that I could see? But you can at least enter your first name and then any other "Family Members". If you touch one of these Names, i.e. Your Name or a Family Member, the App starts looking for your Pulse Device. Simply touch the start button on your Pulse Device and put your finger in the Pulse Oximeter and you can watch your heartbeat and all your stats on your phone. This is logged in the App and creates graphs that track your Stats over time, pretty slick. So contrary to the first 5 Reviews, this App works well and does exactly what most of us would it expect it to do!!! I'd have given it 5-Stars had the implementation been a little more intuitive but it's definitely 4-Stars or Better!!

Literally took me less than a minute for setup. Click the button that says “registered” enter email and the password you want to use. Automatically you will receive an email that’s super basic but has a link. Don’t read the email. It’s not important. Just click the link. It will tell you that registration is a success and then you can use the app. It does have were you can enter your data like DOB, age, and weight but it literally does nothing for the app and has no effect whatsoever on how the app or device works. I love that it records everything! I wish it had a connection to the health app so hopefully they will add that in the future.

We bought this years ago to use in our airplane. Now, with COVID-19, it would be better if it connected to Apple Health and put its data there as so many other apps do. I may need to be able to show my doctor in Apple Health my O2 along with bp and other data. Maybe another Oxi meter would be a better purchase.
