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

Unlock your brain's full potential with the ancient art of memory. Mind Palace transforms how you learn and remember. Using the same memory technique that Sherlock Holmes made famous, you can now build your own digital mind palace, a powerful mental filing system that turns forgettable information into unforgettable memories. WHAT IS A MIND PALACE? A mind palace (also called the "Method of Loci" or "Memory Palace") is a 2,500-year-old memorisation technique used by ancient Greek orators, medieval scholars, and modern memory champions. The concept is simple: place what you want to remember in a familiar location in your mind, then mentally walk through that location to recall everything perfectly. This technique works because our brains evolved to remember places, where food was, where danger lurked. By attaching information to locations, you tap into your brain's natural spatial memory, making recall almost effortless. WHO USES MIND PALACES? • Sherlock Holmes – The legendary detective famously stores vast knowledge in his "mind palace" • Memory Champions – Every world memory champion uses this technique to memorise thousands of digits, cards, and names • Joshua Foer – Author of "Moonwalking with Einstein," who went from journalist to US Memory Champion in one year • Medical Students – Used worldwide to memorise anatomy, drug interactions, and diagnostic criteria • Law Students – Perfect for memorising case law and statutes • Language Learners – Attach vocabulary to locations for rapid acquisition KEY FEATURES Google Street View Integration Turn any real-world location into your mind palace. Walk through your childhood home, a famous museum, or anywhere on Earth. Place your study images along the route and revisit them anytime. Tag & Organise Tag photos with subjects, categories, or any system you create. Build interconnected webs of knowledge that mirror how memory actually works. Unlimited Folders Create separate palaces for different subjects, one for medical terms, another for historical dates, another for that certification exam. iCloud Backup Your mind palaces sync across devices and stay safe in the cloud.
