Kettlebell Timer Pro is an advanced kettlebell workout timer app for iPhone, iPod, and iPad users.

This highly customisable workout timer has a large, easy-to-read display and supports randomisation of work, rest, reps and sets to maximise flexibility in your workouts.

Rotate the screen to view the timer in different ways.

Warning beeps at the end of each rest period allow you to prepare for upcoming sets.

A workout metronome chimes for each rep, and this can be configured for either interval (reps per work period) or cadence (reps per minute) modes.

Interface colours and sounds can also be set using the built-in editors.

All workouts are saved to your iOS device and can be fully edited using the history editor.

Music can be chosen using the lite music interface, or via the standard iPod application.

Workouts can be shared on Facebook and Twitter, and full workout histories can be exported via email and iTunes.

Workouts from the last 30, 60, and 90 days can also be viewed using the built-in bar and line graph display.

Regular updates will be released with new features, which will be free for existing users.
