### 5/5 — Another fantastic derby app!

*2011-06-16*

Ok, Fearless Code has now delivered three critical, great, stable, useful roller derby applications that I have my NSO team use every bout. Totally worth every penny. Beat part of Jam Timer is it accounts for the few second ticking away when you select Timeout and unsure whether it's team or official. It then automatically subtracts as necessary. They really pay attention to the details of what these apps need to deliver.  -Dr. Psycho Cub (GCDG)

### 1/5 — Not working

*2015-09-21*

This app was great to begin with but now it won't load.

### 4/5 — Pretty good, but not customizable

*2014-05-09*

Good app, would be good to be able to sync with iPad or laptop so timer can be broadcast.
Still, it's super handy and easy to use :)
Custom feature is awesome too.
Great job!!

### 4/5 — 30 seconds

*2012-04-29*

Love this app but it would be great if the first jams in P1 and P2 could have a 30 second start. Maybe it does in the settings but I'm not seeing it :(

### 4/5 — A.W.E.S.O.M.E!

*2011-07-05*

Great app. Exactly what i needed. Will be sending this out as a recomendation to all my derby connections. 
For future... Maybe have a way to sync the penalty timer with a main ipad/ipod to keep game stats etc.

Keep developing derby apps! Cheers!

### 4/5 — Excellent app!!

Jam
Counter would be a nice addition to an update!

### 5/5 — Amazing

### 5/5 — Perfect for scrimmages

*2014-04-03*

I referee for leagues without a ton of officials, this app (and it’s PenaltyTimer companion) are perfect for short-staffed scrimmages.

### 5/5 — 5 stars

*2013-09-24*

Incredibly useful and easy to use.

### 5/5 — Jam Timer

*2012-07-10*

I am no longer juggling stop watches, praying I will push the right button in the right order. This app made easy work of my job. I highly recommend this app for anyone who has the pleasure of jam timing.  It is the best app I ever bought. Thank you!!!!

### 5/5 — Must have app for derby

*2012-01-17*

Love, love, love this app. I use it during practice as well as bouts. Makes timekeeping easy, anyone who can use an iPhone can timekeep.

### 5/5 — Great App

*2011-12-09*

5/5 - Really neat app, especially when running with reduced NSO Staff.

Easy to use, with auto settings can easily combine role of Jam Timer & Period Clock
