SCUBA Diary is a free, simple dive log software that exclusively focuses on key features which are necessary for recreation divers to keep track of their dives and memories. It is designed to minimize distractions and optimize a diver's user experience.

One of the most useful features of My SCUBA Diary is its ability to import your dive data directly from your dive computer. You can also import dive logs from Suunto Dive Manager, giving you the freedom to choose how you display and export your dive information. The program supports multiple units of measure and date formats, and all data can be printed out or exported to PDF.
My SCUBA Diary also provides rating and search capabilities that allow you to filter and find your dives based on multiple criteria. It calculates a variety of statistics, including SAC rate trends, for any selection of items from your logbook. You can view your dive profile with marked ascend speed violations and other events.
In addition, the program includes features such as date, time, location, and site of the dive, length of the dive, average and maximum depth, bottom temperature, used cylinder and gas mix, SAC rate, diver's notes, buddy's name, rating, and more. You can also search and filter your dives by dive computer, location, site, notes and buddy, range of dates, dive times and depths, gas mix, decompression events, and dive rating.
Other features include support for multiple user profiles, user-defined gear repositories, user-defined and editable dives, multiple units of measure, import from DM, export to PDF and printing in A4/A5 formats using customizable templates, and automatic update notifications. In summary, My SCUBA Diary is a highly recommended software program for anyone looking to manage their dives efficiently and effectively.
