## What is Nudi?

Nudi is a dive log app for scuba divers — and little by little, your logs become a shared chart of the sea.

■ Dive logging, made simple
Record the date, dive site, point, max depth, water temperature, tank info and more, in the same order as a paper logbook. Start with just the date and site, and fill in the details later. There's a guide signature field too, so you can use it just like your paper logbook.

■ Your logs become everyone's chart of the sea
As sightings and site info from divers' logs add up, you can see what lives in each sea and which points it has. One diver's log helps the next diver plan their dive.

■ Record the marine life you see
Tag the critters in each photo and build your own record of sightings. Search by species to find the sites where they've been spotted.

■ Made for
• Divers ready to move on from paper logbooks
• Anyone who wants to keep a record of the critters and sites they've seen
• Divers who want to know what others are seeing in the water

Every dive adds to the chart. Start logging with Nudi.
