Currently, I'm working on my side project Pomotastic - Pomodoro timer online. Last week I did some significant changes I'd like to share with you. 👉 (1) I made it PWA (Progressive Web App) - look for an icon in your browser's address bar and install the app on your device. 👉 (2) I improved the speed of the app. I used https://pagespeed.web.dev/ to analyze lacks. 👉 (3) I added the state of app preloading. 👉 (4) I changed the UI in general. Thanks to PageSpeed Insights recommendations, it became more darker with significantly better contrast. 👀 See the screenshots of how it looks after the changes. Any feedback is appreciated 🙏
