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

The Task Board is a brand new visual approach to organizing to do lists and notes. This is where you quickly note down and arrange your day-to-day tasks and easily mark them done. You enter your pending tasks on the "ToDo" tab and swipe-off all the finished ones to the "Done" tab. You can intuitively swipe the items back and forth between the "ToDo" and "Done" tabs. The board gives you a bird's eye view of all the items in one quick glance. It gives you a good idea of how many things are pending and how they're grouped. You can re-group and re-arrange the items as and when you like. The smooth scroll and pan gives you the feel of a frictionless whiteboard that stretches quite a bit with central area in focus. You can move the board around and bring any group of items in focus. You can also search for an item which brings the item in the central area of focus. To import a list of text items from any other app, simply copy it there and paste it to the task board. Similarly to do a backup of all the items on the board, select all, copy and paste it in any other app you like. You can do occasional cleanups by selecting and trashing the items. The undo button is helpful if you accidentally do something unintentionally. The task board works in both landscape and portrait orientations. These are some of the things you can do with this task board: - quick one-touch note taking - unlimited board space - swipe-off between the boards/tabs - easy scroll - smooth move around - search - arrange all - arrange related (group) - select on board - copy from board - paste on board - delete from board - zoom in and out with a pinch gesture - undo Enjoy managing your never ending list of day-to-day tasks.
