Dive Log

Read full description

Your dives deserve more than a forgotten note. DiveAtlas is a modern scuba diving logbook that makes every dive quick to record, easy to find, and enjoyable to revisit. LOG A DIVE IN SECONDS Capture the details that matter while they are still fresh: • Dive site and location • Maximum depth and dive time • Water temperature and visibility • Buddy, dive center, entry type, and equipment • Ratings, notes, photos, and memories BUILD YOUR PERSONAL DIVE ATLAS See your dive sites on an interactive map and keep a lasting record of the places you have explored. Search your history and return to any dive without digging through paper logbooks. UNDERSTAND YOUR DIVE HISTORY Follow your progress with personal statistics including total dives, deepest and longest dives, average depth and duration, recent activity, and trends over time. USEFUL TOOLS BETWEEN DIVES Keep equipment details close at hand and use the no-fly-time reminder as a planning aid. DiveAtlas is a personal logging tool and is not a substitute for dive training, professional advice, a dive computer, or established safety guidance. KEEP THE MEMORIES Add photos and personal notes so every log contains more than numbers. From a first certification dive to a favorite reef abroad, your underwater story stays organized in one place. SYNC WITH iCLOUD (OPTIONAL) Turn on optional iCloud Backup to keep your dive log private to your Apple ID and restore it on another iPhone or iPad. DIVEATLAS PRO DiveAtlas is free to download. Optional DiveAtlas Pro monthly and annual subscriptions, or a one-time lifetime purchase, unlock unlimited dive logs, depth-history insights, and dive-frequency trends. Payment is charged to your Apple ID at confirmation. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period and can be managed in your App Store account settings.
