Great app

At the risk of sounding dramatic I have to say this app has improved my life . I work all shifts with mixed up hours and I'm more rested and alert by waking up with this simple alarm. I fall asleep sooner with the surf sounds offered. The only change I’d make is report more stories. It’s been a long time! Try it!

Ambient Sounds

It’s a shame the ambient sounds aren’t more persistent and only go up to 90 min - it could even be a premium feature to get a full 8 hrs. I woke up 6 times in the night after it cut out (by the app’s own measure) so paying for this app isn’t worth it to me. I ended up so awake before I should have been that I didn’t even get to use the alarm feature.

Watch Ultra

Sometimes when I track with phone and watch, journal crashes and doesn’t record night

Not easy to amend

Finding this app useful but knocked stars off because you forget to turn it off you cannot edit your wake time and this skews your data !

Recordings?

Reused and recycled…Lately when I listen to the recordings I notice only the last five are actually from last night’s sleep. The rest are collections from the past and it is of this I am certain for very specific sounds only happen in certain places. For example; in the heat sometimes I sleep in a different location in our house where the ceiling fan makes a distinctive clicking noise, the one in our bedroom is silent. The recording taken of my dreadful snoring last night included the fan of the room I was not in… disappointing.

I have recommended this App to many and now I may have to search for a new one. You can’t fool a fool!
