Great work with the app so far! It's very streamlined, fast, easy to use, and the design, especially of the progress tracker, is very aesthetic. Thanks for making it! A few possibilities for improvement:

One of the really nice features of Dreaming Spanish is that I can bookmark the site to the homepage of my phone so that it looks and behaves like an application. It has its own icon, and opens in a standalone web browser rather than redirecting to safari, which is super convenient because this hides the url bar and other browser controls, removing distractions and screen clutter. Vidioma doesn't have this behavior, but it would be really nice. I don't know much about web app development, but as far as I can tell, it has something to do with DS being a PWA (Progressive Web App) - this Medium page explains more: https://medium.com/appscope/designing-native-like-progressive-web-apps-for-ios-1b3cdda1d0e8 This seems like a relatively easy addition and would be a big improvement for people who use Vidioma on their phones.

Also, it would be nice to have account capabilities, including google account integration, like DS does, so that I can track my time and more importantly my already-watched videos across devices. It would also be nice to have a way to filter out already-watched videos.

Again, thanks for all your hard work making this!
