The logs are not exportable through the app. The temperature logged is the coldest. The dive is recorded as a graph of depth and time. I logged 2 dives yesterday both starting at 5-8 feet of depth.
The information logged is: Date and time / duration of dive / dive number if more than one dive that day/ breathing gas / average depth / Max depth/ water temp (coldest) / pictures and videos taken during the dive.
There may be a app that lets you export the info from the Igills app, I just write it in manually in my log book.
I use the Igills for the picture and video and the compass when it does not lock up. The dive computer works well and is very easy to see in light or dark situations.
The customer service blows and the only email response that you will get is when you place a order, the only time you will get a response to a question is by logging into your order and sending the question through their order area several times.
