Solid foundation, needs some polish
This app has a good base. The core functionality of chatting and calling works well, and the integration with Firebase is seamless. The UI is functional but feels a bit clunky in places. Some of the animations are a little jarring, and the overall design could benefit from a more modern aesthetic. There are a few minor bugs; nothing game-breaking, but certainly noticeable. It's a decent starting point for someone who wants to build on it, but it's not quite ready for prime time as is. I'd recommend some improvements to the user interface and ironing out the smaller issues before releasing a fully polished product.
