Yea. I bought autosleep and was not satisfied with it. But that is only my experience about it. Even with autosleep app the true sleep stages etc. are quite far away from truth, save your money. The default is good enough.

edit: if you want to record your snoring and possible sleep apnea sounds then it might be good for you. But sleep apnea can also be silent like in my case.

I used it for a while but didn’t like it. The sleep tracking is not that much accurate. Sleep tracking devices like Oura, and Smart Watches tracks sleep stages with 50-60% accuracy, my doctor told this who works at sleep clinic. Apple and Polar devices has the best sleep accuracy.
