About this app
Your dive logbook, digital and yours forever.
Dive Log is a private scuba logbook for your phone. Log a dive in about a minute, watch your depth and time records build, and export the whole dive log whenever a dive shop asks to see it. No account, no cloud, no agency lock-in — your dive logbook lives on your device and stays there.
LOG A DIVE IN A MINUTE
Site, max depth, duration — that is all a dive needs. Everything else is optional and waiting when you want it: entry time, average depth, water temperature, visibility, breathing gas and nitrox mix, cylinder pressure in and out, weight carried, exposure suit, buddy and notes. Metric or imperial, switched any time: your dives are always stored the same way, so changing units never changes a single logged value.
BRING YOUR PAPER LOGBOOK ACROSS
Already carrying a paper dive log? Tell Dive Log how many dives you have done and your numbering picks up where the paper left off — a diver with 180 dives starts at 181, not 1. Add your recent dives and your certification the first time you open the app, and the scuba logbook you have carried for years becomes searchable, backed up, and impossible to leave in a hotel room.
YOUR RECORDS, CLIMBING
Deepest dive, longest dive, total bottom time, dives per year, most-dived sites, gas breakdown and the buddies you dive with most. A scuba diving log is more than a list — it is the picture of the diver you are becoming.
EXPORT FOR ANY DIVE SHOP
Boats and dive centres ask to see a logbook before an advanced course or a deeper dive. Export your scuba diving log as a PDF laid out like a classic paper logbook page, or as CSV for a spreadsheet. You can sign your dives on screen with a finger, exactly the way you would sign a paper page.
EVERY TRIP, ORGANIZED
Group a week of diving into one trip and see it whole — every dive, every site, the totals for the whole trip.
GEAR AND CERTIFICATIONS
Track your regulator, BCD, computer, suit, fins, mask and cylinders. Set your own service interval and Dive Log reminds you when it comes around. You choose that interval, because a service schedule is your manufacturer's and your service centre's call, never ours. Keep your certifications in the same place — level, agency and card number, typed exactly as your card reads.
WORKS ON A BOAT
Everything works with no signal at all. There is nothing to sign into and nothing to sync, so the app is exactly as quick on a liveaboard or a RIB as it is at home. No ads, ever.
WHO IT IS FOR
New divers logging their first dives after certification, holiday divers who want one dive journal instead of a drawer of paper, and experienced divers backfilling hundreds of dives into something that will not get lost. Freedivers and snorkellers use it as a simple dive diary too.
WHAT IT IS NOT
A personal record — not a dive computer, not a dive planner, and not a substitute for training or dive tables. Dive Log records the dives you have already made. It does not compute decompression status, no-stop times, gas consumption or exposure limits, and it never will. Read your own instruments, follow your training, and dive within the limits you were taught.
PRIVATE BY DESIGN
No account, no email, no sign-up, no ads, nothing uploaded. Your dive journal, your certifications and your gear stay on your phone, and a backup is text you keep yourself. Dive Log is not affiliated with, endorsed by, or approved by any diving training or certification agency, and it does not verify certifications — the agency and level fields are simply your own text.
BUILT TO OUTLAST YOUR PHONE
A logbook is a permanent record, so nothing in it is trapped. Back up your whole dive log as plain text you keep yourself, and restore it on a new device by pasting it straight back. Export a PDF or CSV copy any time you want one that does not depend on this app at all.
Free to download, and it works the moment you open it.
