Easy to use providing google or Microsoft doesn't intentionally inhibit your phone from downloading apps that are perfectly fine for older phones like android 5.0. they need to be upfront in that you need an outlet that's close to your bed and that your phone needs plugged in all night. challenge when the new phones don't include wall charger (causing you to spend triple resources to go find one), and the ones they give you now only have like 2 1/2 feet of cord. but nighthawk is outstanding!

Useless. I'm supposed to do a two night sleep study. The first night it failed. I figured it was user error. The second night was successful. But it has absolutely refused to upload. I have a fast internet connection. It will not let me record another night until that one uploads. I'm waiting to hear back from the powers that be.

Does Not Work. Last night the app itself froze and it would not respond this morning. It would not stop recording so I closed the app and re-opened it. Once I did that I was able to stop recording. Then I get an error message stating that it didn't record because the sensor wasn't connected even though I followed the set up instructions perfectly. I've had 1 successful night out 5 recording data for this test and ive done the exact same thing every night for the test. So it's definitely not me.
