Dive Log: Scuba Diving Logbook

A scuba dive log for repeat entries and a logbook you can take with you: Log like last dive, saved Templates, CSV, limited UDDF, a whole-logbook PDF and a Verified backup.

▶ REPEAT THE SETUP, RECORD THE DIVE

• Tap Log like last dive on the Log screen or on a previous dive. It carries over site, country, buddy, gear, gas, weights, units and cylinder setup.

• Save a setup from the dive editor as a named template for a boat, shore or pool dive. Start a New dive from Templates, then enter that dive's readings.

• Repeat entries get a new dive number and the current local date and time. Depth, duration, pressures, notes, photos and annotation start fresh.

• Set date and time with steppers or Today and Yesterday. A field that needs a fix is marked.

▶ TAKE YOUR LOGBOOK WITH YOU

• Whole logbook PDF: one printable file with a page per dive, with notes and the drawn sign-off annotation. Progress is shown and you can cancel.

• This dive PDF: share or print one dive's page from the dive editor.

• CSV export, or a limited UDDF summary with site, local date and time, depth, duration, recognized gas and tank pressures.

• Verified backup holds dives, templates, sites, buddies, gear and certification card photos, with photos in separate parts checked after writing. Share all backup files sends the manifest and every part in one share step.

• Restore backup shows a preview with record and missing-asset counts before Merge into logbook.

▶ KEEP THE DETAILS TOGETHER

• Record maximum and average depth, duration, water temperature, gas, weights, cylinder size and pressures. Add notes and photos.

• Complete single-cylinder open-circuit entries show SAC and RMV estimates in bar/min and L/min or psi/min and cu ft/min.

• Metric or Imperial: values are shown rounded, and switching units does not shift saved values.

• Browse dives on a depth gauge or by date; type a site or buddy name to find dives.

• Save sites with coordinates, buddies and gear. Gear shows a badge when service is overdue or due within 30 days.

• Stats: recorded dives, bottom time in hours and minutes, deepest dive, totals By site and By country.

▶ GOOD TO KNOW

• A manual logbook: dive-computer transfers, dive planning and decompression calculations are outside its scope. SAC and RMV are estimates from your entries.

• UDDF has no depth profile, photos, buddy, gear, notes or sign-off; import depends on the receiving software.

• PDF pages list photo filenames without embedding photos; the backup carries photo files.

• A drawn sign-off is an annotation, with no identity or qualification check.

• Photos up to 8 MiB each. Location access is optional for site coordinates.

• Records and copied photos are saved in the app on this device. The app keeps the five newest exports and three newest backups; share or save copies you want to keep.
