An enhanced version of HiMemo, an easy and convenient hierarchical memo app, is now available! For example, there is a surprising amount of information that has a hierarchical structure, such as information linked to regions and organizational charts. Normally, such information is recorded in bulleted list format in the memo app, but adding or editing information is surprisingly troublesome. Inadvertently, problems such as breaking the hierarchical relationship will occur. With HiMemo2, information can be recorded hierarchically with a simple operation like bulleted list format, and it is easy to add or modify. It is also possible to display a tree that gives a bird's-eye view of the whole, and to export information to other apps and SNS in plain text format or HTML format. Features of HiMemo2. - You can easily enter and manage data with a hierarchical structure. - Share data between multiple iPhones, iPads, Macs (sync with the same Apple ID). - You can browse the data on your Apple Watch. The following functions have been enhanced and improved from HiMemo. - Data is synchronized with HiMemo. - Linked with Apple Watch. You can browse the data on your Apple Watch. - The search function has been enhanced, and you can now search across memos. - The UI is simpler and easier to understand. Data will be inherited from HiMemo, so if you are using iOS 15 or later, we recommend migrating to HiMemo2.

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? β€’ Sherlock Holmes – The legendary detective famously stores vast knowledge in his "mind palace" β€’ Memory Champions – Every world memory champion uses this technique to memorise thousands of digits, cards, and names β€’ Joshua Foer – Author of "Moonwalking with Einstein," who went from journalist to US Memory Champion in one year β€’ Medical Students – Used worldwide to memorise anatomy, drug interactions, and diagnostic criteria β€’ Law Students – Perfect for memorising case law and statutes β€’ 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. Never lose your carefully constructed memory system. Complete Privacy Your study materials and mind palaces stay on your device and in your iCloud, never on our servers.
