Been using Penalty Timer 4 Roller Derby for a couple months now. It’s basically an app that helps you time penalties and other events during roller derby matches. Pretty solid app if you’re into that kind of thing.
Here’s what you do: you can set up timers for one or two teams, and it’ll give you a visual and audio countdown when there’s 10 seconds left. And there’s also the option to customize team names and colors, plus you can even put your league’s logo or other images as the timer background. Took me a while to figure out all the settings but it’s useful once you get it set up.
Look, if you’re a roller derby fan, you’ll probably like this. It’s not perfect – the ads can get a little annoying if you don’t pay – but overall it does the job. Worth checking out if you need a reliable penalty timer for your games.
