You start preparing using flashcards, where answers are provided on the back of the flashcards. Then you can bookmark flashcards which you feel difficult and think that you don't know the answer that well. You can access the bookmarked flashcards in a different section so that you don't have to go through the list of questions. You can test your knowledge using in-built quizzes. You can create your own quizzes by customizing it by bookmarking quiz questions. Once you submit the Quiz/Test you'll be provided with your result and you can take tests unlimited number of times. This app is also equipped with creating your own course material and notes. Suppose your want to log your dive information or if you are using another text book, this app will help you by creating custom flashcards. You are able to create custom chapters and flashcards with questions, answers and options. For custom flashcards, you are able to attach images to your flashcards. Following is the description how to attach images to your custom flashcards. LEARN HOW TO ATTACH IMAGES You can attach up to 5 different images in a single custom flashcard using '[attach1]', '[attach2]', '[attach3]', '[attach4]' and '[attach5]' anywhere in question, answer or any of the wrong options. Once you write these keywords, upload attachment buttons will start enabling where you can upload an image from your phone. Uploading an attachment needs to be in sequence meaning you can't enable '[attach2]' before '[attach1]'. Example: Question: What is happening in the picture? [attach1].

Underwater navigation is the one dive skill that gives you no feedback. You swim a square, surface forty metres from the shot line, and neither you nor your instructor can say which leg went wrong. Landlubber gives you the feedback twice: once on dry land, where the drill can be watched, and once underwater, where it has to be swum. ON LAND Walk the pattern with your phone as referee. It reads your heading, counts your steps, and afterwards draws the shape you actually walked against the shape you meant to. Indoors a corridor is enough. Outdoors it takes a fix and measures how far you finished from where you started. IN THE WATER Five dive sites you brief, slate and swim. Study the chart on the boat, choose what goes on your slate, pick the visibility and the current — then the chart is gone and you have the compass, the count, and whatever you wrote down. The reckoning afterwards lays your track over the plan. One of the sites is the real thing: the El Aguila, a freighter sunk off Roatan and broken into three by a hurricane, from a photogrammetry survey of the wreck where it lies. THE INSTRUMENT A working dive compass in three dimensions. Turn it in your hands, tap any part, and read why it earns its place on a dive. Turn the bezel with two fingers, exactly as you would underwater, and feel it click. ONE CAGE, ALL DIVE Set the bezel so N sits caged between the two index markers. From then on you never read a number again — you keep a graduation in that cage. N going out, S coming home, N, E, S, W round a square, without touching the bezel at any corner. THE PATTERNS, WALKED AND SWUM • Reciprocal — out on a heading, back on its opposite • Square — four legs, four right turns, back to the start • Triangle — three equal legs and 120-degree turns • U-pattern — long lanes and short hops, mowing an area • Expanding square — legs growing by a pair, out from a datum SEARCHES Two of the dives hide something. A camera slipped somewhere near a datum block; a marker buoy went over the side onto a wreck's deck. Both land somewhere new every time, so the pattern is what finds them, not your memory of where it was last dive. TUTOR AND EXAM Tutor shows every number and ticks on each step it sees. Exam hides them and asks you to commit your own count before the reveal. WHAT IT WILL NOT DO It is not a substitute for water time. Buoyancy, trim, gas, task loading and a real buddy are absent here, and they are most of what makes navigation hard. What it replaces is the guesswork in the debrief. Made by a technical diving instructor. No accounts, no tracking, nothing leaves your phone. Free: the instrument, the reciprocal drill complete, and the house reef dive. One optional purchase opens the rest of the ladder, on land and underwater. Paid once, no subscription.
