Mnemonizer hides your PIN codes and passwords in a camouflaging environment, making them uncrackable for frauds and undetectable for spying eyes. ○○○ “Mnemonizer provides a novel security approach, enabling you to obscure your codes in plain text.” – TUAW ○○○ HOW IT WORKS The system generates a mnemonic card with a cell field. Each cell starts with a random editable value - number/letter/symbol and color. All you need to do is choose a place, where you’d like to hide your data and edit the corresponding cells. Place your data on the field in any convenient way (in a simple line, in a zigzag or even as a skip pattern). Then mentally mark its position, give a name to the card and your stored information is ready to use. On second opening, your brain instantly recognizes the position of the data, while everyone else sees a mess. In a variety of up to 9,223,372,036,854,775,807 (2^63) of possible arrangement combinations, guessing or cracking gets impossible. Thus, yours will stay only yours. FEATURES - your data stays safe at all times, even if someone sees your screen - hide passwords and PIN codes among random symbols on mnemonic cards - store all data on one card or create separate cards for different data - nothing to intercept or spy, thus nearly impossible to crack - automatic iCloud sync and backup ○○○ More from Happymagenta: · Spyglass - outdoor GPS with augmented reality · Scany - WiFi scanner and network utility

This app shows different strategies to think and learn new topics. The tools are essentially speed-learning hacks. You can learn anything with this app. We show you how to become more creative. Learn what is essential and be able to think critically. We believe that learning is about understanding and not learning things by heart like brain zombies. We want you to become brain users who consciously choose how they think and learn. Why Assocy? We chose the name to make a connection to associate thinking. This is your brain's preferred working mode. There is no isolated information. If I ask you to not think of a pink elephant. Please do not think of a pink elephant! Did you do it? Of course not. The moment the words ‘ pink elephant’ entered your mind, all related topics become active. The task I ask you for is impossible to accomplish. These associations are part of our thinking process. But instead of fighting your brain, you could choose to use associated thinking to your advantage. To learn more effectively and enjoy it. Part one of our toolkit The strategy we propose is very efficient. It seems too easy to work. But it has been successfully tested in German schools for 20 years. You can try it if you want. All you need is 20 minutes per day for 1 month. Chose a topic you want to improve on. Then write a list of all the things you know about that topic. The more lists you write the easier it gets to access this part of your knowledge. After a month the topic will be active in your mind. We keep track of your progress so you can see your success. We also included training for learning what is essential. Part two - the fun games can begin Writing lists is by itself useful, but you can play with them too. Since we keep them organized for you, you can easily reuse them. Categories games The goal: gain a deeper understanding, structure your thoughts, and get an overview. You might have the feeling new information our overwhelming and they are flying around in your mind like a stock of bees. This means your mind is trying to find a context for the new information. This is a bit like looking for a drawer, where the information belongs, and you can later find it again. We can help this understanding process by asking the right questions. You use your list and try to categorize them. Find the right categories that fit all the items on your list. You can repeat the game and see how your perspective of the topic can change. Mind-maps and infographics The goal: visualize a topic, structure, organize material If you are a visual learner or like to move when learning this one might be perfect for you. We provide a canvas on which you can draw with your finger or an Apple pencil. You can also scroll through your lists and drag and drop items on the canvas. You can move the items around and connect them by drawing on the canvas. Since you wrote the lists once, you can reuse the items as often as you want. Creative Thinking and Leonardo da Vinci The goal: think outside the box, and generate ideas. Leonardo da Vinci is known as a great thinker with an extraordinary ability to look at the world from an unusual perspective. This did not appear out of thin air. He developed strategies to think more creatively. If he had a subject or problem to study, he would try to make connections to seemingly unconnected things. He found that the human mind will always find a connection between two objects, no matter how remote they are from each other. These connections can be extremely interesting, give new insight or offer a creative solution. The method of LULL also helps to connect the unconnected. By combining lists from different topics, we have a lot of possible connections. Not every connection is good, but if you try enough you will eventually find great ones.
