I like to make Android apps for fun and for profit. The most successful project I have worked on is an app called "EveryCord", which has over 15 million downloads. You can check it out more here, or here
EveryCord is a screen recorder for iOS (no JailBreak), Android (no root), MacOS, and Linux. I made the Android version, Anthony Agatiello made the iOS version, and Colton Adamski manages it all so it doesn't burn to the ground. You can download it here, or on Tutu App, or on AppValley. it is also available on the Google Play Store!
