TwentyFiveInFive - A simple but useful app combining a lap target timer and a stopwatch...

TwentyFiveInFive, as the name suggests, was initially created for Roller Derby players who are aiming to pass or improve on their minimum skills lap test.

This app can be used by anyone though; cyclists, runners, non Roller Derby skaters, fitness fanatics, motocross riders, and really any athlete in training. Probably not swimmers though...

The benefit of having this app on your phone is that you can listen to music whilst training, or time someone else's laps, while they do their lap target test. 25in5 isn't just a lap-target test for Roller Derby, it features a stopwatch with millisecond accuracy, and the ability to post stopwatch times to Facebook or email them to yourself - or someone else - if you're that way inclined...

The lap-target mode uses rollers to allow you to set the amount of time, and the number of laps you'd like to bleep in that time. It helps by showing you the equivalent laps per minute and seconds per lap, so you can get a handle on your target times.

In lap-target mode you get a 5 second countdown after tapping start, then the phone bleeps every time you should lap. If you're dexterous enough, or you don't use both hands heavily in your sport, try using the stopwatch at the same time!

In stopwatch mode the buttons flick between start|reset and stop|lap, so you can be confident of hitting the right button and not ruining your timing.

You can set the volume for the bleeps also, in case you are listening to music whilst training, and the buttons are large, making it easier to start and stop the timers, especially when busy.

For less than the price of a half-pint of my favourite beer, you cant really go wrong.
