I've used this app for a few years over many iOS updates and 4 iPhones. I love it. How it records before I make a sound is pretty neat, however, it shuts off at any point in the middle of the night. I have contacted these developers several times, and have yet to get a response. I have to dock what would otherwise be a rave review 2 stars for this. Excelltech, answer your emails.

I have tried several other recorder apps, and this one is the most reliable and easiest to use. It is basically a voice-activated recorder with time stamp so you know when the recordings took place. In the morning, you get one file with all the noises in it. You can play all of them sequentially, one at a time or non-stop, or use the scroll bar to jump through the night to a certain time. It always shows you when the noise took place. The buttons are not too small, the graphics are clean and easy to read. I don't use the categories -- I just listen to what happened overnight andI don't usually export the files, although you can. Helpful not just for apnea sufferers, but for people who talk in their sleep, or wonder when external disturbances occurred, or wake up with great ideas in the middle of the night -- just say it when you think of it. I like the app, I use it every night, and I highly recommend it, especially over others that try to do the same thing. And when there was a problem with a recent update, I e-mailed the developer, received a prompt and pleasant reply, and a fix was posted the app store within 10 days.

This app is great. Lately though it only records half of the time even though I set it and it shows it is recording- it doesn't. Then recently it didn't record the first 2 hours. It has helped a lot using it to see just how many distractions I have to my sleep during the night. For example: I found I snore which I didn't know- I am small and so my Dr never tested me for sleep apnea- because if this app I got tested and was found to have it. I also learned I probably wake up a lot because of my peta who are up partying during the night.I haven't figured out how to classify each noise yet and so every noise it set to "unanalyzed".

I've been wondering why I wake up at night so often so when I saw this app I decided to try it. I ran it last night and was pleasantly surprised at how well it works. You just start it running, then turn off the phone by the top button (these instructions are clearly dislayed on the app as well). In the morning it had recorded 29 disruptions and my battery was only down about 25%. It was easy to go through and listen to each distraction and categorize them. I wish the app had more types of disruptions, as well as being able to add my own. Once categorized, it would be nice to have some type of graphing feature so you could see over time the most types of distractions and the time of night. Anyway, great idea for an app. I look forward to using this every night for a while and seeing if I can make changes to reduce the numbers of distractions. At my advancing age sleep is so important.
