Great Monitor
I haven’t used the app yet, but overall, the actual device itself works great for me. I love how quickly it turns off so it doesn’t waste battery and has been pretty accurate for me.

Easy to use and value of money
Its simple and very easy to use. You will have to download another app, but other than that its pretty much very nice.

tracks o2 and ecg while you sleep perfectly. and inexpensive!!!
it does exactly what it says, it uses a 3rd party app and that works well. it tracks oxygen levels and charts it for you. ecg also. it shoed my levels dropping low early then higher later. the reason for 4 stars is the battery life. batteries last for 1.5 nights. not that handy eating batteries but it does run sensors all night. for the price its amazing. it will tell you what your looking for and do it easily without setup or connection hassels

Seems to work okay
A pinch sensitive to positioning on your finger. Use your middle finger and get it in as deep as it can go (comfortably) – on any of these sensors. Sure, you can use any finger, but the larger the skin surface and blood flow, the more accurate the measurement. The laser is basically looking at the color of your blood – through – your skin. So wash your hands (engine oil, sun screen, etc will degrade the reading) and watch out for callouses. The sensor doesn’t care about the color of your skin. It cares that it can bounce light off the capillaries I didn’t try the the blue tooth feature or download the software, but I did get a reading in my blutooth list that it had found it. It can only be registered for use if the software is installed. My phone would not connect to it because I did not download the software.

Works well
I purchased this to help me keep track of my oxygen levels more regularly. It works great. I really like the app feature that keeps track of all of my information on my phone. Small and lightweight, easy to carry. Very affordable.

Accurate to within 5% of my reading at the medical faclity, good enough for screening
I bought this to follow my oxygen levels while I was sleeping. First off, the instructions are just barely adequate. I downloaded the app onto my google phone (it doesnt work with my amazon/kindle fire reader), updated the software, and good to go.A couple of negatives here; while it saves the info in a graphical form, the data cant be sent or opened as a spreadsheet for manipulation. There is a specific order to how to turn off the oxygen meter or it wont save the data you just recorded. It eats AAA batteries, goes thru a set a night but the battery indicator will let you know in advance. The meter O2 number rapidly flashes sometimes, figured out this is due to the O2 number being below their preset alert number (I think it is 88%?) but no mention of this in the manual or after contacting their customer service (they asked me to send a vid of the “problem”). Overall, i give the meter a 4, good value for the money; and the instructions, manual etc. I give a 2.
