Randomix - Decision Maker
APK
Introduction 👋 This is an app created as a demo of some Android features. The main purpose of the app is to provide a random choice in different ways. The app contains some basic personalization options and an introduction, plus some new resources like animated vector drawables and the full light theme. The design is a bit personal: it follows the Android guidelines, but just partially. Why should i use Randomix? 😕 Well, i'll tell you 3 main reasons: It can help you to decide randomly in 4 different ways, elegantly! It will cost just 3MB of storage! It's beautiful, full of animations and simple to use! An example? → During a table game, you have to throw a dice, a coin, or choose which player should start: Randomix does it all! → You're hungry but you and your friends can't decide a place to have a meal: just spin the roulette and accept its wise answer! → You're starting to develop apps and you need a simple app to look at, to find some inspiration and tricks: click on the Github link, and the Randomix source code is served! Features 🎲 Every tab in the bottom navigation bar contains a type of random choice. The available types are: Roulette → select an option from a list. Coin → simply flips a coin and prints the result. Dice → throws a dice and prints the result. Magic Ball → provides randomly chosen answers to any question. The recent options used in the roulette are automatically saved and can be restored! Roulette presets, such as 1-100 numbers and letters Shake to launch option Light, dark and Amoled themes, Material You Up to 10 dice and different dice types, plus a 3v3 mode Selectable accent Android 13 per-app language and themed icon support Vibration and sounds Rude answers, allow equal options, dice number First time introduction Multiwindows support Simple and precise ui following the material guidelines Credits ⚡ This app was written during my free time as a training. Many good devs have helped me understanding the best practices. Thanks to BValeo for the russian translation, and to Firokat for the french translation. And a special thanks to Stack Overflow, obviously.

Privacy Friendly Reckoning Skills helps you improving your mental calculation skills in the four basic calculating operations. For each game, the player can choose between the four basic arithmetic operations and four difficulties (exercises up to 10, 100, 1000 and 10000). After finishing an exercise round the player receives a score which depends on the number of exercises answered correctly and the time it took to answer all ten exercises. After every game there is an overview which shows whether the exercises were solved correctly. It is also possible to choose "Direct Feedback" in the settings. If direct feedback is chosen, the player will receive feedback whether the exercise was solved correctly after each single exercise. How does Privacy Friendly Reckoning Skills differ from other similar apps? 1) No permissions Privacy Friendly Reckoning Skills does not require any permissions. For comparison: The Top Ten of similar apps from the Google Play Store requires an average of 3,4 permissions (in November 2017).
