## What is Kodo?

Kodo lets you feel the heartbeats of different animals through your iPhone's vibrations and animation.

A human heart beats about 70 times a minute. A sparrow's beats around 800 times, and an elephant's only about 20. Numbers like these are hard to imagine, but in the palm of your hand the difference is unmistakable.

- A collection of heartbeats
Nine animals are laid out like specimens in a display case: human, sparrow, elephant, octopus, chicken, cat, dog, horse and mouse. Inside each outline, a red heart beats at its real pace.

- Feel it through vibration
Choose an animal and your iPhone pulses at its heart rate. Small animals beat fast, large ones slowly. Close your eyes and compare.

- Heart rates that change
Switch a human between rest, exercise and sleep, or a horse between rest and full gallop, and the heart rate changes with it.

- Heart monitor view
Switch to text view to see every animal's heartbeat at once as a moving ECG trace, like a hospital monitor.

Heart rates are approximate.
