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!

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. ### 1/5 — What Analyzer? *2014-09-03* It doesn't analyze anything other than recording the sound you make while sleeping. That's not sleep analyzer. If you are looking for an app that actually analyze your sleep pattern, you need look for better app than this one. Not worth the price. ### 5/5 — Still Best by test *2014-08-15* 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. ### 1/5 — It's useless *2014-01-25* This app is useless the microphone does not function when you start the sleep analyzer. So no recordings are made. A total rip off. ### 5/5 — Like it very much. *2013-09-16* It worked perfectly first try. First night it gave me all the data about my snoring etc. that I could have wanted. Will continue to use it. Good job! ### 4/5 — Works great when it works *2013-04-27* 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". ### 1/5 — Last update hurt this apps functionality *2012-11-17, version 3.20* Since the last update was released, I have received only two types of results when I set it to record my sleep at night: 1. It crashes as soon as I hit the Stop button without saving a recording file for that sleep session. 2. It saves a recording of the sleep session, but only the first few minutes are recorded. No other noises made during the night are picked up regardless of how low I set the decibel level. ### 2/5 — Analyser *2012-10-26* It's okay at recording but u have to download a program on to mac to save the previous nights recording. And that does not work on as mac says downloaded file is damaged. So this works but saving recordings to mac. Forget it. ### 1/5 — Disappointing *2012-06-19* This app only allows you to tag disruptions with "Sneeze" and "Cough"! How about sleep apnea, snoring, talking, external noises? It should at least allow you to add your own categories. This seems a pretty half hearted attempt at an app that should not sell for more than $1. ## Frequently asked questions about Sleep Analyzer ### How does Sleep Analyzer work?
