Kaku is a fast, powerful Japanese dictionary that stays on top of all your apps. It uses optical character recognition (OCR) technology to recognize kanji on the device screen for you (rather than the slowww tedious process of looking up individual characters manually), making it perfect for Japanese learners who want to study by reading raw manga, play untranslated games, and so on without the hassle of switching apps.

Kakugo is an application that helps learning Japanese. It includes multiple tests to memorize hiragana, katakana, and kanji and adapts to the user's learning pace. One of the biggest difficulty with learning Japanese is memorizing kanji and vocabulary. While learning them by just reading and writing them everyday may work, the more kanji you know, the harder it gets and the more time it takes to revise them all. Proper tools can help you memorize these huge amounts of knowledge to more quickly become a fluent Japanese speaker. Kakugo is one of these tools. It helps learning and revising kanji and vocabulary in an efficient manner. It uses Spaced Repetition in a unique way that adapts to the user's pace. If you only have time to revise 30 kanji every day, or if you can revise as much as 100 kanji every day, Kakugo will adapt and test you on the right kanji at the right time for you to memorize them. There is no "kanji of the day" list to revise, you can start and finish a session whenever you feel like it. Kakugo also features a wide variety of tests to help you find the best ways that will help you learn Japanese. Features include * Hiragana, Katakana quizzes * Kanji quizzes by reading and meaning * Kanji test by part composition * Kanji writing test * Vocabulary quizzes by reading and meaning * Unique spaced repetition formula that adapts to your own learning pace * Unlimited quiz sessions that allow you to take a quiz at any time, for however long you want, useful to efficiently spend commuting time * Show similar-looking kanji in answers to teach you the differences * Kanji and vocabulary sorted by JLPT level * Clicking on kanji opens aedict3 (a non-free Japanese dictionary) or jisho.org * Optimized tablet support * Open source * No ads * No internet access required * Supported languages: English, French * More to come Credits * The kanji quizzes are based on kanjidic. * The vocabulary quizzes are based on JMdict. * The kanji similarity database comes from https://minerva-access.unimelb.edu.au/handle/11343/35336 and http://lars.yencken.org/datasets/phd/ * The kanji composition and drawing database comes from KanjiVG.

Kanade is a simple app that allows you to extract apk from your apps list. Fully open-source and zero-ads. Works for Android 4.4 or above.Installed apps from PlayStore doesn't expose their apk installation files by default. So if you want to share some app you will need to send the PlayStore link. So if you are offline or the app is no longer available on the PlayStore you won't be able to share the app.So here we are, whatever the reason, if you want to share some app directly through a p2p connection (Bluetooth, Wifi-Direct, etc.) you can use apk extractors! These kind of apps allow the user to extract the hidden apk files from almost any installed app to a visible location (e.g Downloads folder).

A simple application that lets you draw Japanese characters (kanji) using the touch screen. It is intended for Japanese language learners who might need to enter characters in order to look them up in a dictionary or enter them on a website. It identifies the character you have drawn using a special form of handwriting recognition. You can select the correct character from a list. After entering one or more characters, you can copy them into the clipboard as text for use in a dictionary. Note that this will NOT work - at all - if you don't know basically how to draw kanji. If you just draw something any old way that looks like it, it certainly won't be recognised. You have to draw characters basically the official way. This is a fork of the Kanji draw application from https://github.com/quen/kanjirecog/ which is no longer maintained and was removed from F-Droid. Two of the included icons were taken from the Android SDK and are licensed under the Apache License 2.0. The kanji stroke data is based on the KanjiVG data set from http://kanjivg.tagaini.net/ and licensed under the Creative Commons Attribution-Share Alike 3.0 license.

Keep Alive will send a custom message via SMS to one or more people if you haven't used your device in a given period of time. Intended to be used as a failsafe for those living alone in case of an accident or other emergency. Once the settings are configured, no further interaction is required. - 100% Device-based, no cloud services or accounts required - Free with no ads or trackers - Open Source (https://github.com/keepalivedev/KeepAlive) - Minimal Battery Usage - Multiple SMS Recipients - Custom Alert Message - Optional: Include Location Information in SMS - Optional: Place a phone call with speakerphone enabled - Optional: Send an HTTP request to a custom URL Requirements Keep Alive requires that your device has an active cellular plan. WiFi calling and messaging will be used if the device supports it. How it Works Keep Alive uses either your device's lock screen or another app(s) to detect activity. If your device hasn't been lock or unlocked for a set period of time, or if you haven't accessed the selected app(s), you will be prompted with an 'Are you there?' notification. If this notification is not acknowledged an Alert will be triggered. Based on the configured Emergency Contact Settings, one or more SMS messages and/or a phone call will be placed to notify others that you may be in need of assistance. Main Settings - Monitoring Method - Choose between using the lock screen or another app(s) to detect activity. If using another app(s), you will be prompted to select the app(s) to monitor. - Hours of Inactivity Before Prompt - how many hours since your phone was last locked or unlocked before you are prompted with an 'Are you there?' notification. Defaults to 12 hours - Minutes to Wait - if the prompt is not acknowledged within this time, an Alert will be sent based on the configured emergency contact settings. Defaults to 60 minutes - Rest Period Time Range - a range of time during which inactivity will not be counted. For example, with 'Hours of Inactivity' set at 6 hours and a Rest Period of 22:00 – 6:00, if the device is last used at 18:00, the 'Are you there?' check would not be sent until 8:00. Note that an alert can still be sent during a rest period if the 'Are you there?' check was sent BEFORE the start of a rest period. - Auto-Restart Monitoring After Alert - If enabled, monitoring will be automatically restarted after an Alert is sent. - Alert Webhook - Configure an HTTP request to be sent when an Alert is triggered Emergency Contact Settings - Phone Call Number (Optional) - when an Alert is triggered a phone call will be placed to this number with speakerphone enabled One or more SMS recipients can be configured with: - Phone Number - the phone number to send the Alert SMS to - Alert Message - the message that will be sent when an Alert is triggered - Include Location - if enabled, your location will be included in a second SMS Privacy/Data Collection No data is collected other than the configured settings. This data is not shared with the developers or any 3rd parties. The only data transmitted is to the configured emergency contacts. This app does not request network or storage access and no data is sent to the developers or any 3rd parties. Disclaimer - Not responsible for SMS or phone call charges incurred by the use of the Keep Alive app - The operation of the Keep Alive app is dependent on the device, software, and network connectivity. The developers are not responsible for any failure due to device malfunctions, software incompatibilities, or network issues.
