While the Apple iPhone and iTouch have been gaining increasing popularity with the public, software developers have also been busy creating an ever-expanding database of handy applications for the iPhone. It was only a matter of time before developers began creating applications catered to Scuba Divers. There are currently quite a few apps already available at the iTune store, and we have compiled a two part list of some of the more popular ones.
(If you haven’t read PART-1 of this article Click Here)
Dive-Log
Ever wanted to carry your Scuba logbook with you wherever you go? The Dive Log app allows you to add full details about every single dive or location and create a separate profile for every dive conducted. The profile contains the date, time, location, GPS coordinates, length of the dive and other specifics such as buddy, weight and equipment used etc. Additionally the Dive-Log app allows you to add photographs as well and even lets your Dive Master sign the entry electronically. The biggest benefit of Dive-Log is that its is able to convert all details into Universal Dive Computer Format (UDCF) files in order to allow the user to retain logbooks on their desktop computers and use other 3rd Party Diving Log applications simultaneously.

I suggest divemategps as divelog and diveplanner.
it’s really easy to use. only you have to do is just a few touches of icon array after divings.
every data is recorded in the form of icons and images – of course, some text description you can insert – and you can upload it on mash-up server and share it with others all over the world which also means you can see others dive event via application searching feature.
visit app store! so much other dive apps are there.
but, you feel amazing with this apps while you are using it sub dive log.
