Mnemosyne
APK
Mnemosyne, named for the Greek goddess of memory, is an app designed to aid one in remembering lists of related information. This particular memorization scenario is underserved by more traditional flashcard/memorization apps such as Anki. For example, if one is learning German, one would eventually have to memorize a list of around 50 verbs that are the so called "dative verbs". One could try to make a really big singular flashcard, or attempt something like cloze deletion, but these are very clunky methods. With Mnemosyne, one can simply enter the list items one at a time and get feedback on which ones were missed. One could then focus on just those items that are commonly missed or continue trying to get a perfect score on the original list. For convenience one can import a csv file into the app to create lists, or just create them manually. The csv must have a header row with the columns "Title" and "Items". Separate each item in the items column by the separate delimiter "#@!". Within a csv file, can specify multiple lists, one in each row. One can also export lists to save elsewhere. There is a feature that allows for placing related lists together in a collapsible group. One can nest these groups to near arbitrary depth. One creates a group by prefixing the group title to the list title, followed by "::". For example, to create a grouping of German lists, where one wants a list of nouns and a list of verbs, one would name the two lists German::Nouns and German::Verbs.

Morse
APK
Decipher Morse code to text or text to Morse code Turn any text into Morse code, or translate Morse code to text and hear the results. • Clean, modern app design and interface. • Made to be simple to use for everyone. • Realtime translation: type in the word or code and have it translated immediately. • Decode from Morse to text, or text to Morse. • Press the speaker button to hear the code. • Copy the text by pressing the "Copy" button. • Type in dot and dash using our built-in Morse keyboard. • Libre software (https://github.com/Crazy-Marvin/Morse) + More features planned. Don’t let the special characters or dots and dashes befuddle you. Morse code is a system to encode letters and numbers to dash and dot signs. The duration of the dash is three times the duration of a dot. Each dot or dash is followed by period of signal absence, called a space, equal to the dot duration. Morse code was first used for communicating via telegraph. The most well-known Morse code is SOS, which is used to signal an emergency. Aside from typing dots and dashed, you can also signal Morse code by turning light on and off, sounding a horn or tapping, etc. All means of transmitting Mores code require the recipient understands it. If not, our app may be used to find out the message, password, secret number, or any info you want to relay. Nowadays, even though the use of the telegraph has been widely superseded by other communication technologies, Morse code still finds its place in the lives of various individuals. Due to its presence in popular culture, Morse code has been featured in movies, games, and other medias as a simple way to encode messages, inspiring fans to research and explore the language as part of fun, puzzle-solving activities. This makes it useful even in cryptography or cryptogram events as a handy encoding tool. 1. Tell others when you are in a dangerous situation (SOS). 2. Hide your secret number or password via dots and dashes. 3. Cipher or decipher hidden clues in games. 4. Learn cryptography or cryptogram through learning Morse codes. 5. Become a codebreaker by breaking secret codes in real time translation. 6. Create a secret number. + Many more --- It really helps to leave a review or to star the project in the source code repsitory, and it means the world to us. If you have problems using the app, please write an e-mail or open an issue on GitHub. Responses are most often immediate, and bugs are fixed as soon as possible.
