Very pleased with the usability of this app. Would like to see a HD option with this app. Otherwise, really good.

This really is an excellent app. I'm a medical doctor and suffer from sleep apnoea. Take the time to set the threshold correctly. I've found about 70 dB ideal for my situation. After having a dental appliance made for me for my apnoea (the appliance moves the lower jaw forward to stop the soft palate occluding) I was able to adjust the appliance little by little each evening until I stopped snoring and having apnoeic events, completely. Once you've recognized you have occlusive sleep apnoea, I suggest you do something about it. Carefully logging events etc is not going to alter the management. Just get it treated!

This is an especially useful app for assessing OKN (both vertical and horizontal) in babies. Have found it easier to use on the iPad than the iPhone. Nevertheless have still used it on the iPhone. The Amsler is handy as well. I like being able to use it white on black which is sometimes more sensitive than black on white.

I found that after downloading he app I had to restart my iPad. Then it works ok. There is a wealth of very valuable information that's free. So it's great value and well worth h time taken to download and restart the iPad.

Love this app. However, I'd love to be able to organize the documents and to rename them as well. Really would like to have folders as well.
