Kriptofolio
APK
This app will track all your cryptocurrencies in one place and let you know how much they are worth converted to fiat money.The important thing for the user is that this app is going to ensure 100% trust. It will not require any login/registration process. It won’t collect users’ data by sending it to the server. Users’ provided data about cryptocurrency investments will be only stored inside a local database that is kept inside an Android device. However, to know the portfolio’s value converted to the fiat money, the app is going to use the Internet to get the latest conversion rates.As the topic of money for people is so sensitive, to ensure trust, this app. is being developed openly by creating blog posts series and making the project code available so everyone can see that there is nothing to hide.

KryptEY
APK
Communicate securely and independent, regardless of the legal situation or whether messengers use E2EE. No server needed. #ChatKontrolleStoppen Why KryptEY? Breaking of end-to-end encryption (E2EE) by laws such as the planned EU chat control is an ongoing issue. Content in messengers that use E2EE, such as Whatsapp or Signal, could thus be monitored by third parties. E2EE is often, but not always, standard in messengers. There are proven methods for E2EE such as PGP. However, these methods are sometimes cumbersomely integrated and require a lot of effort to use. KryptEY is an Android keyboard that implements the Signal protocol. The keyboard works messenger-independently and both the X3DH Key Agreement Protocol and the Double Ratchet Algorithm work without a server, thus it enables a highly independent use of the protocol. Features Based upon Simple Keyboard ( https://github.com/rkkr/simple-keyboard ), KryptEY adds a view above the Keyboard for the E2EE functionality. * use E2EE through Signal Protocol in any messenger * encryption/decryption of messages * enter message through separate text field in keyboard * use clipboard to read messages * manage contacts in own contact list in keyboard * message log to view sent/received messages * send messages as plain JSON (raw mode) or hidden in a decoy text (fairytale mode) * verification of E2EE functionality via fingerprint * Q&A View for questions * dark & light theme See https://github.com/amnesica/KryptEY/blob/master/KRYPTEY.md for further information on how KryptEY is working. Security The existing security properties for the Signal Protocol are also valid for the keyboard. Limitations The keyboard was designed as a POC and only allows 1-to-1 conversations. However, the application can also be used in a group chat to a limited extent. Here, a message can be directed to a specific chat partner and not to all people. Other participants of the group chat cannot decrypt the message. Text messages in Telegram are getting copied as HTML and not as plain text. When decoding the message with the fairytale mode the copied message is compromised and can't be read properly. Therefore, it can't be decoded at all. However, the raw mode works properly. When using KryptEY with Telegram we recommend the raw mode. Some messengers like Threema only allows up to 3500 bytes per message. Therefore, different character input limitations apply. To stay under the 3500 bytes limit, only 500 characters are allowed for raw and fairytale mode. For convenience these limitation applies for all messengers. Demo For a demonstration on how KryptEY is used see https://github.com/amnesica/KryptEY/tree/master#demo KryptEY was created by mellitopia and amnesica. The code is open source and can be found at https://github.com/amnesica/KryptEY

Kuaizi IME
APK
筷字输入法 (Kuaizi IME) is a system based on the combinatorial features of Chinese Pinyin. It is an efficient and fast input method editor, suitable for electronic touchscreen devices. 筷字输入法 (Kuaizi IME) abandones the traditional method of tapping on virtual keyboard keys one by one, it instead offers a swipe input method for Pinyin, combined with the combinatorial features of Pinyin letters. The key layout is designed to make Pinyin input more accurate and convenient. 筷字输入法 (Kuaizi IME) provides editing support such as cursor movement and text selection for the target editor, thereby eliminating the frustration of being unable to accurately position inputs and text due to the small screen size of mobile devices. This further enhances text input and editing efficiency on small-screen devices. User-data generated by 筷字输入法 (Kuaizi IME) is stored locally. It does not connect to the internet and will not collect nor analyze user data or behavior habits. Furthermore, it does not support or provide predictive input nor fuzzy matching mechanisms. To some extent, this input method editor aims to enhance the users' ability to recognize and memorize Chinese characters and Pinyin, ensuring that the reliance on digital tools does not lead to the gradual forgetting and eventual abandonment of 「汉字」(Hànzì, Chinese characters), a treasure of Chinese civilization.

APK
Kwik EFIS is a Glass Cockpit application designed to work on most Android devices. It provides a modern aviation glass cockpit attitude and flight instrument display. Digital Moving Map The built in map module provides situational awareness and and navigation functionality. EFIS can optionally integrate with the Stratux ADS-B/AHRS to provide real-time traffic overlay. Synthetic Vision Synthetic vision is built from the USGS 3 arc second Digital Elevation Model data. If enabled, it also allows for some terrain collision detection. The required terrain data packages are available via F-Droid, see: https://f-droid.org/en/packages/player.efis.data.usa.can - North America, Canada https://f-droid.org/en/packages/player.efis.data.eur.rus - Europe, Russia https://f-droid.org/en/packages/player.efis.data.sah.jap - Sahara / North Africa, India / Indonesia, Japan https://f-droid.org/en/packages/player.efis.data.eur.rus - Southern Africa, Australia / New Zealand https://f-droid.org/en/packages/player.efis.data.pan.arg - South America https://f-droid.org/en/packages/player.efis.data.ant.spl - Antarctica / South Pole Flight Director Kwik EFIS has a fully functional flight director built in. It uses the standard V-Bar symbology common to modern flight directors. The target waypoint and altitude is set on-screen by means of the spinner controls on the right top and bottom of the screen. Airspace Airspace data is provided from Worldwide Soaring Services Turnpoint Exchange Airspace (http://soaringweb.org/Airspace/) ADS-B/AHRS In addition to the internal sensors, a low cost Stratux ADS-B/AHRS can be selected as the input source. See http://www.stratux.me/ for more information. Simulator There is a simulation mode available in the application. The Flight director is used to select a waypoint and altitude and the simulator will generate the GPS movements to navigate to the selected waypoint. The speed is set at the typical cruise for the currently selected aircraft. Installation For application and installation help, see: https://ninelima.org/efis/instructions.html

Kõnele
APK
Kõnele is an app that offers speech-to-text user interfaces to other apps. Many apps contain a text area or a text field (e.g. a message box or a search bar) that can be edited using the input method editor (IME), aka the on-screen keyboard. Kõnele provides an IME that is optimized for speech input. Modalities like swiping and buttons are also supported, for situations where speaking is less convenient. Many apps (e.g. intelligent assistants, navigation apps) also contain a microphone button that is linked to the standard Android speech recognition activity. Kõnele provides an implementation of this activity, and uses it itself as a launcher. Kõnele can connect to any speech recognition service available on the device but by default uses, and is optimized for Kõnele service (https://github.com/Kaljurand/K6nele-service), a separate lightweight app whose backing server runs the kaldi-gstreamer-server (https://github.com/alumae/kaldi-gstreamer-server) software. The default server operates from Tallinn and provides Estonian speech recognition, but the software is easy to deploy elsewhere (e.g. a private network) and customize for other languages. (Note that Kõnele also includes a simpler version of "Kõnele service" under the name "Kõnele (fast recognition)".)
