Can anyone recommend a decent app from the app store for keeping up to date with champions, big fight schedule and other key features?

Preferably one that isn't full of ads, bloatware and paid services.

All the ones I can see in the app store and Google play are complete shyte.

Every major boxing fight that has taken place in the last 20 years has likely been talked about here.
You don't need need an App.

Yh, if there’s a fight worth talking about. I’m gonna make a thread on it.

If you want just schedules.

ring magazine and DAZN website have scheduled fights.
