ScubaDen: Your Diving Universe

Every dive tells a story. ScubaDen keeps them all — and everything around them.

Your logbook. Your buddies. Your gear. Your dive sites. Your plans. Your progress as a diver. Most apps handle one piece of your diving life — ScubaDen is the den where all of it lives. Connect your dive computer and watch your logbook build itself. Ask AI anything about your diving. Plan a technical dive down to the minute. Message your buddies about Saturday's wreck. One app, your entire underwater world.

A LOGBOOK THAT BUILDS ITSELF
• Import dives straight from your dive computer over Bluetooth — full depth profile, temperatures, tank pressures, gases, and deco data
• Interactive dive profile graph with the key events of every dive
• Add dives manually if you dive without a computer
• Attach dive sites, buddies, and equipment to every dive
• Sort, search, and bulk-edit your entire dive history
• Works offline — review and log dives on the boat with no signal; everything syncs when you're back online

AN AI THAT KNOWS YOUR DIVING
• Instant AI analysis of every logged dive — ascent behavior, gas usage, deco, and what to watch next time
• Ask questions in plain language: "What was my deepest dive this year?" "Which site do I visit most?"
• Insights across your whole logbook — trends, personal records, and breakdowns by site, buddy, season, and gear

A TECHNICAL PLANNER IN YOUR POCKET
• Full decompression planner powered by the Bühlmann ZHL-16C algorithm with gradient factors
• Multi-level dive legs, multiple deco gases, and surface intervals for repetitive dives
• CCR bailout and lost-gas contingency planning
• Depth, time, and bottom-mix variations at a glance
• Save and reuse plans and settings templates, then link a plan to the dive you logged

YOUR CREW, IN THE DEN
• Build your buddy list and see the dives you share with each buddy
• Chat one-on-one or in groups, and drop dives right into the conversation
• Share any dive with anyone via a link — no account needed

YOUR SITES, YOUR GEAR
• Keep your personal dive-site collection, and discover featured ScubaDen sites and public sites from other divers
• Track your equipment in a personal gear locker with maintenance reminders — your regulator service will never sneak up on you again

No dive computer? No problem — log dives manually and still get sites, buddies, gear tracking, and AI insights.

From your first open water descent to your hundredth trimix run, ScubaDen grows with you — and helps you become a better, safer diver with every dive.

Important: the dive planner and AI analysis are informational tools. They are not a substitute for proper training, conservative planning, or your own dive computer. Always dive within the limits of your certification.

This isn't another logbook. It's where your diving lives. Welcome to the den.
