Pretty simple interface. Could be a little more user friendly, like if I wanted to change the layout or commands. It takes a little finagling, but it’s pretty straight forward. Definitely don’t download it the day of the game haha. It uses the old school style of lineups, the ones used in college or club, and then when it’s game time, it automatically moves them around so they face each other. So if you’re not used to that lineup, it’s disorienting. But it highlights who your captain, setter (optional, in case they’re the same), libero. You can put in subs, but it still shows the number the sub came in for. I was a score keeper for 20 years before I was a ref, so it was refreshing to use something that had that in mind. Issues I found were the inability to change the length of the timeouts. Only 30 seconds allowed. Also, how do I delete a match?? I played around with it a bunch, and have several fake matches in my queue, but no way to delete them. I don’t want it to clog up my page. I showed it to another ref and she thought it was pretty cool, too. No ads, no weird issues. Just you and the score, I like that.
