App is broken and owners ignore user complaints


This app is completely broken and the owners have ignored the users for months. I was patient before leaving a bad review. In the past you would get redirected out of the app 3 or 4 times in a row by pop ups. Today you can't even open the app. This doesn't happen with any other app. It's the most common complaint on their forum and the admins ignore it while enjoying the ad revenue. And that's just one issue of many. The app is a message board but it's broken and threads take hours to update. You can make a post and it won't show for hours.

Dis honest owner's, little concern for user experience


I used to love this app and website. The latest updates and site owner behavior has changed that. This USED TO BE hands down the best MMA site and app by a long shot. Not anymore. We users get it that they have to make money. The owners do not get (or just don't care) that they are ruining the experience.

New update is loaded with pop ups and re directs. Seeing ads is fine. Constant re directs or pop ups and pop overs are not. Especially for members who pay to support the site

Forum posts do not show up without doing multiple manual refresh commands

"News" page has changed to site owners opinion pieces mixed with pasting other people's articles

Site owners start multiple forum threads boasting "new" app updates when there hasn't been update in over a month. Clear attempt to coerce users into updating.

This place used to be great. Now it's sad and shameful.

Grabbing for money and only one person’s opinion


You are constantly directed out of he app to download other apps. Also, the number of advertisements have become ridiculous. To top it off, the only person that writes editorials(really just Op Eds) is the owner of the site Kirik Jenness. He seems like to inject his opinion into stories way more than they need to be. At one time this app/website was the place to find news on mma, now it’s gone the way of the MMA Torch app.
