For 2 years I have discovered a new passion in my life: mobile app development. I, Initially started with Java/XML for Android and, for about a year, I discovered Flutter/Dart for both Android and IOS.
The things are simply amazing. The only barrier in front of your own accomplishments is only your imagination. I have already 2 apps published on Google Play Store with the links bellow. Try them, they are free and with no ads. Simplicity and utility is my main goal, and after that I will advance to something more complex and visually enhanced.
