Simple Coin Flip

12 years later... The original Simple Coin Flip - now completely rewritten using modern Android development practices. Still completely FREE (no-ads) and doesn't require any unsafe permissions. Now includes all 50 USA state quarters! Simply tap the question mark or shake and view the result. Tap the coin or shake to spin the coin again. Verify the flip algorithm is truly random by running the built-in Diagnostic Test and flipping the coin 100,000 times (or more) while watching the results in real-time. (Sorry, no cheating!) Open source code released to the public domain. Check it out here: https://github.com/banasiak/CoinFlip2 Quarter-dollar coin images from the United States Mint. Presidential $1 Coin images from the United States Mint. === What's New? === Exactly the same as before (almost), but completely rewritten using Modern Android Development (MAD) standards. Kotlin, coroutines, MVVM, Material 3 with dynamic colors. You know, all the cool stuff. Can you believe I still have the original code signing key for this app? Unfortunately, I'm not interested in Android Wear anymore, so no watch support. Sorry, but go buy a G-Shock and you'll be happier. Oh, and Google finally realized that having an official API for loading resources from any app installed on your phone was not great from a privacy perspective, so no more support for "add-on packs". If you bought the Simple Coin Flip Mega Pack in the past, I appreciate it. This new version has all 50 state quarters included for free.
