Repetition Configuration

This section allows the user to configure timing parameters related to the “On your marks” and “GO” signals.

Starters Pause

This is the pause time between the “On your marks” sound and the “GO” sound.

Race Repetitions

This is simply the number of times that the “On your marks” and “GO” signals will be played.

Sounds

This section provides selection of the “On your marks” and “GO” sounds.
There are several built in sounds available or custom sounds can be selected from your music library.

About

Swim Start is a simple training aid for race start practice.

It is an Apple iOS app compatible with iPhone, iPad and iPod touch.

Start swim groups at fixed intervals with configurable “Take Your Marks” and “GO” sounds.

Swim Start simplifies the coaches job by providing an automated starter at the swim blocks, allowing coaches to position themselves at other locations around the pool to monitor and record swimmers performance.

The Swim Start app can be controlled remotely with your iPhone.

About the author : David Mayes

I swim to keep fit with a Masters swim squad.

My coach, Alan Godfrey, asked if anyone knew of an app that could emit a start tone every 10 seconds so he didn’t have to run from one end of the pool to the other when timing 50m sprints.  The SwimStart app was born.

Apple iOS programming is a completely different field of programming for me and has been a very interesting challenge.
