Language Selector
APK
Language Selector allows users to set individual app languages. It tries to replicates the behavior of the "App languages" feature introduced in Android 13.To use the app you must be on Android 13 or higher, there is no compatiblity with older Android versions. You also must have Shizuku installed.Before using this app, you MUST install and start Shizuku, the way this app works makes Shizuku MANDATORY.Features:Set individual app languagesAllows selecting language from any app **Quick change languages with QSTile** Language Selector DOES NOT translate apps, it just specify a locale that will be used by application, if the desired language is supported by the app, it should be displayed as expected.** Please note that changing locale for unsupported applications and system apps may cause unexpected behavior and is NOT RECOMMENDED.Language availability:This app parses Locale (java.util.Locale) from Locale.getAvailableLocales(), consequently, numerous locales are present in the app, the language list is huge, if someone want to improve that, feel free to send a PR, because this way is pretty slow and languages aren't filtered accurately.

Learn reading (in french)

You will find activities such as: * Associate a word with its image. * Find the missing syllable of a word. * Put in order the syllables or letters forming a word. * Write the word (dictation). The word sets are classified into 7 difficulty levels which follow the usual progression of the teaching of reading: starting by simple syllables (in P T M L R), then we go gradually towards more complex syllables. These activities were created voluntarily as part of the Afrikalan Project, which aims to make free educational software accessible in West Africa. They are distributed free of charge and in a non-commercial manner, under the terms of the GNU-GPL license.
