Hey, I know this thread is a few months old but in case you are still curious about these sleep tracking app, I wanted to give some input.
I use the Sleepzy app on my iPhone x. So far I’m fully satisfied with the same, it’s sleep cycle tracker will analyze your sleep throughout the night and gives you the report in the morning. There is a sleep debt feature, on which you can determine the difference between your sleep goal and the actual amount you had!
I was an IT professional for the past five years. Of course, I had struggle sleeping as my job was of high pressure, demanding in nature, super long and even I had onsite sleep shifts!
Now I turned to another field and working on my health. I’m on medication now and I use a memory foam mattress, Memory Foam Mattresses | Mattressville (If that helps someone) for the past few months.
And the sleepzy app was suggested by my doc, Yeah, it works super fine for me!
