PenaltyTimer App Reviews

Loved using the app instead of multiple timers. So simple to use and easy to see time left.

this is great for derby geeks like me. helps when we have limited nsos. thanks!

super easy to use, and easy on the wallet compared to a number of stopwatches, love being able to stop all timers simultaneously when the game clock stops. Well get lots of use out of this!

Perfect timer for penalty boxes. Our NSO and Ref crews are always asking for people with iPhones and this app to donate them for games.

Great timer!! Better then using a stop watch and works great with the new rule set

The updated version handles 4.0 "jammerless jam" rules beautifully! One volunteer with limited training can easily run the entire penalty box. Every league needs this app for practices.

If you have a iPhone and work as an official in roller derby, this is a must. Works 100%. The girls in the box find it much easier to read what their time remaining is. Just make sure that you set the phone into airplane mode to keep anyone from calling/texting you while timing penalties.

We need more derby applications!

Does just what it says - just tried it out at an intra-league game and it worked flawlessly; lets one person run the box easily, and follows the 4.x jammer penalty rules seamlessly. This is an example of great programming - nice work!

What a great penalty tracking app! In the past Ive done the stopwatches taped to a clipboard trick, but not only does this app make tracking penalties faster, it also saves you the problem of missing a stopwatch when tracking multiple people in the sin bin. AND it has the forethought to allow you to set custom penalty times, such as someone getting a double-major or when a jammer becomes a blocker due to a jammerless jam.

As a new NSO and learning all the tips and tricks to running the penalty box, this App is a godsend. It incorporates the full Jammer rules, and you can turn them on and off. Its an App every Derby player, NSO, and Ref should have. The vibrate feature is wonderful! I havent had a problem with it yet. Oh and it is great for practice jams too. With the manuel time set function, you can start a Jam with a Jammer or Blocker in the box for a simulated ammount of time of your chooseing. Put it this way. You could buy 6 stopwatches; or spend the $3 on this wonderfull app. Its a win win situation. Just cant wait for an iPad version ;)

It makes being the penalty timer very easy. A must have for all leagues.

This app is amazing! I was able to run the penalty box by myself. It was so easy and fun. I was upset that more people didnt get sent to the box so I could use it more. This is a must have for any derby team.

We have 2 of these apps on 2 different phones for all the potential ref squads. This is a wonderful timekeeper that is easy to learn and use. We play under MADE rules, and it is very easy to convert the app to a generic ruleset. If you are a MADE, OSDA, or ref a league other than WFTDA, you will not be disappointed.

I use this app every time I NSO in the box. I love that you can time Jammers only, 2 teams, 1 team or just Blockers. I also love that you can stop and start all timers at once; very helpful between jams and during timeouts. You will not regret this purchase. -Double Dstruction, Green Mountain Derby Dames

Love it and use it every chance I get. Also great for Junior Bouts when the volunteers arent trained as well and helps them keep track.

This app is the de facto standard for roller derby penalty timing. Well written and perfect for use in WFTDA and MRDA bouts.

This app makes penalty tracking so easy. With built in jammer rules, anyone can run a sin bin!

Love the app, well worth the price.

This makes box timing so easy! One feature request: Ability to set the default time to 30 seconds - we often use shorter penalty times during short scrimmages.
