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].

Deco Room is the course theory, planning tools and emergency reference for technical and rebreather divers. It is built for boats and remote sites, where there is no signal. There is no web page hiding inside this app. Nothing needs a connection to read a second time. COURSE THEORY Full written theory for the courses you are training on, in chapters you can read in a sitting rather than a syllabus you scroll past: • KISS Sidewinder MOD 1 — sidemount closed-circuit rebreather • Technical Diving Fundamentals — decompression, gas, procedures • Dive Computers and Decompression Management Chapters open with a question before they give you the answer, because you remember what you had to reach for. Diagrams, worked examples and interactive widgets are drawn live rather than pasted in as pictures, so they scale with your text size and stay legible on deck in the sun. PLANNING TOOLS Calculators that show their working: • Maximum operating depth, equivalent narcotic depth, best mix • Gas density against the 5.2 and 6.2 g/L limits • Surface air consumption and respiratory minute volume • Rock bottom and minimum gas • Isobaric counter-diffusion check • Partial-pressure blending • CNS oxygen clock • No-stop planning on ZH-L16C with gradient factors Every input is a bounded control, so you cannot quietly produce an impossible answer. THE EMERGENCY CARD Reachable before you sign in, and it works offline: • What to do before the call: diver out, flat, warm, oxygen on • The DAN and local emergency numbers for your region • An SBAR call script you can read straight down while somebody else asks the questions • A field guide to recognising what you are looking at REFERENCE LIBRARY Once you are enrolled, a shelf of curated diving and hyperbaric literature that opens inside the app, plus an offline search index over the research so you can look something up on a liveaboard. ACCESS Anyone can create an account and use the calculators, the schedule and the emergency card. Course theory and the library open once your instructor has enrolled you. These are taught courses, not a subscription. Deco Room is made by Donarun Das, a technical and rebreather instructor. The numbers in it are the ones taught in the courses. Not a substitute for training, supervision or medical advice. Decompression diving carries risk that no app removes.
