I thank you for finding an alternative. Although the power of the app is unmatched by the site. There are reminders in the background and you can manage selected events conveniently from the notification bar. It must also be said that a dedicated app responds to the rules of the operating system, I can decide how to set the aggressiveness of battery optimization. A browser has too much surface area, and what is good for two hours of live events then becomes unnecessarily energy-intensive the rest of the day.
