Sleep Analyzer

By Excelltech Inc.

Open iTunes to buy and download apps.


Do you wake up feeling tired and groggy? Are you going to bed early but still don’t feel fully rested in the morning? You may be having trouble sleeping through the entire night. The average adult needs between 7 and 8 hours of uninterrupted sleep to reach regenerative REM cycles. If you awake during the night due to coughing, sneezing, or other ailments, you may never reach a deep sleep and remain drowsy throughout the day.

In the past, logging these sleep disruptions was tedious at best. Traditional recorders left users pouring over hours of tapes trying to identify and write down each disruption. Sleep Analyzer simplifies the process by using a decibel threshold system and easy to navigate interface.

Simply place your iPhone next to your bed and set a decibel threshold for the night. Only sounds that exceed that threshold are recorded and stored for you to access the next day. The threshold system allows you to quickly overview the number of disturbances in a night, and avoid pouring through hours of recordings to document your sleep patterns.

The next morning you are able to scroll through each disruption. Disruptions can be replayed and classified as coughs, snores, sneezes, etc. You can store up to a month of sleep data and back-up data to a personal computer. The organized sleep logs can be used to identify recurring disturbances that can then be presented to a doctor or remedied through tailored changes to your sleep environment.

Don’t be satisfied with low quality sleep and poor energy levels – let Sleep Analyzer help you identify your problem and track your progress to a restful slumber!

Still Best by test

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.

Works great when it works

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".

No Support

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.
