7 Tips to Get the Most Out of Dive Ledger

Log Your First Dive

The best time to log a dive is while the details are still fresh. Was it 18 meters or 22? Starting pressure 200 bar or 210? Those numbers slip away fast. (I personally take my phone on the boat and log between dives. Most phones these days are water resistant enough to handle it.)

• Open the Ledger tab and tap +
• Fill in what you know: depth, duration, temperature, gas mix, visibility, water type, current
• Tag the dive site and drop a pin on the map so you can find it again
• Add photos and note any marine life you spotted

You don't need to get everything perfect on the first pass. You can always come back and fill in gaps later. The point is to capture the dive while you still remember it.

Your Certificate Card, On Your Phone

You're at the dive shop counter. They need to see your Advanced Open Water card. Your wallet is back at the hotel. Your certification agency's app won't load because the WiFi is barely working.

• Go to Profile > Certifications
• Add your certificates (PADI, SSI, NAUI, SDI, BSAC, whatever agency you trained with)
• Snap a photo of the physical card for a visual backup
• Add your certification number and date earned

Everything lives on your phone after that, and it works offline. No more fumbling through email looking for a PDF while a line forms behind you.

Got a Dive Trip Coming Up?

Dive trips have a lot of moving parts. You're researching sites, figuring out what gear to bring, making sure you don't forget anything. The Plan tab lets you sort all of that out before you leave so that once you're there, you can focus on the diving.

• Create a trip with your dates and destination
• Build a packing checklist so you don't realize you forgot your mask strap at 30,000 feet
• Add planned dives for specific sites you want to hit, with any details you already know (depth, notes, what to look for)
• After each dive, convert the planned dive into a logged dive with one tap. The site, your depth estimate, and notes carry over. You just update it with what actually happened.

The idea is that you do the planning work once, and then logging becomes quick edits instead of starting from scratch every time you surface.

Who's Your Dive Buddy?

Maybe you have a few people you dive with regularly. Maybe you just met someone on the boat and did a great dive together. Either way, Dive Ledger lets you keep track of who you dive with and what you did together.

Ways to add a buddy:

• QR code: show yours on the boat, they scan it, done
• Find by email: look them up and send a friend request
• Share an invite link: send it over text or your messaging app of choice
• Add an offline buddy: for people who aren't on the app yet. Add their name, certification level, and contact info. If they join Dive Ledger later, you can link their account and all your shared dives transfer over.

Once you're connected, tag them in dive logs and compare stats side by side. And if you share a dive with a linked buddy, they can add it to their own logbook with one tap instead of logging the whole thing again themselves.

What Do Your Dives Say About You?

The Stats tab gets more useful the more dives you log. After a dozen entries it's interesting. After fifty it starts to tell a real story about you as a diver.

Everyone gets:

• An overview of your total dives, bottom time, average depth, and average duration
• Personal records: deepest, shallowest, longest, coldest, warmest, best visibility, best SAC rate
• Monthly dive frequency chart
• Milestones and achievement badges as you hit dive count, depth, and geographic milestones

Premium unlocks:

• Trend charts for SAC rate, depth, duration, and temperature over time (filterable by 1 month, 3 months, 1 year, or all time)
• Breakdowns by water type, dive type, suit type, current conditions, and depth range
• Explorer stats: unique sites, countries visited, top buddies, and species spotted
• Gas analytics: SAC rate by depth range, consumption by tank size, and a tank duration predictor
• Year-over-year comparisons of your dives, depth, duration, and air consumption
• Buddy correlation: who you dive with most, and how your stats compare when diving with different people
• Seasonal patterns: which months you dive most, and how conditions change across seasons

The Premium stats are for divers who want to know if they're actually getting better at managing air, or just telling themselves they are.

Share a Dive, or Take Your Data With You

You just did a great dive and want to tell someone about it. Or your buddy was on the same dive and doesn't want to log the whole thing from scratch. Or you want to move your data to a new phone, or bring in logs from a dive computer. All of that is covered.

Sharing:

• Tap Share on any dive to generate a link. Anyone can open it in a browser, no app needed. They see the full dive: site, depth, photos, marine life.
• Share directly with a linked buddy. They get a notification and can add the dive to their own logbook with one tap instead of re-logging it.
• Share as an image card to social media or messaging apps.

Exporting and importing:

• Export your full logbook as CSV, JSON, or UDDF from Settings. Good for backups, moving to a new device, or keeping a copy outside the app.
• Import dives from another app or a dive computer in the same formats. Duplicates are detected automatically so you don't end up with double entries.

No lock-in. Your dive data is yours. If you ever want to move to something else, everything comes with you.

Log Dives Faster With Gear Defaults

Most divers use the same gear on almost every dive. Same BCD, same reg, same wetsuit. Typing all of that in every time you log is tedious, and it's the kind of small friction that makes people fall behind on logging. Gear defaults fix that.

• Add your gear: BCD, regulator, wetsuit, fins, computer, torch, SMB, whatever you carry
• Mark your usual setup as favorites
• New dive logs auto-fill with your favorites
• Rented a BCD or switched to a thicker wetsuit? Swap that one item, everything else stays

It takes a couple minutes to set up once. After that, the gear section of every new dive log is already filled in, which makes a real difference when you're doing three dives a day on a trip and want to log each one between surface intervals.
