About
DiLoTA is a dive logbook for divers who write their own entries.
Most dive apps are built around pulling data off a dive computer. If you dive on rented gear, or a few times a year, those apps ask you for something you do not have. DiLoTA does not.
WRITTEN FASTER THAN PAPER
Three fields make a record: bottom time, max depth, and when. Everything else is optional and folded away until you want it. Your dive sites, buddies and gear are remembered, so the second dive at a place starts nearly filled in.
A SIGNATURE, LIKE THE PAPER BOOK
Hand the phone to your buddy or instructor and let them sign with a finger. The signature keeps the name and certification recorded on the day, even if their details change later.
WHAT IT WORKS OUT FOR YOU
Air consumption (SAC), surface interval, cumulative bottom time. Approximate figures for your records — DiLoTA does not plan dives and does not calculate decompression.
TOOLS FOR BEFORE YOU GET IN
Nitrox limits, best mix, air consumption and how long your gas will last. Every formula is the one your agency taught you, and each screen names it. The gas planner starts from your own consumption rate — measured from the dives you have already logged, not guessed at.
A PAGE YOU CAN HAND OVER
Export any dive as a one-page PDF: your entry, the calculated figures, the signature. Print it, email it, show it to an instructor.
YOUR RECORDS ARE YOURS
Export everything as a spreadsheet or a data archive, at any time, on any tier. Nothing is ever locked away, and nothing is ever deleted.
FREE TO START
Log your first dives free. Premium adds unlimited entries, PDF export, full statistics and iCloud sync across your devices.
Available in thirteen languages, in metric or imperial.
