There are many walking apps out there. Some are designed to count your steps, while others estimate how many calories you burned. Eighty Thousand Steps is different — this one unlocks a story, one step at a time. Through a vivid soundscape, you'll retrace the steps of a hero on the search for home.

Created by writer and journalist Crystal Chan and developed by Stitch Media, Eighty Thousand Steps is a unique immersive and interactive podcast experience that is powered by your pedometer. It's about family, migration and the tales we pass on through generations.

The fictional tale was inspired by the stories that Chan's grandmother told her on their walks together when she was a young girl. It tells a fantastical story filled with adventurers and monsters but as you listen along, you begin to uncover another story — one of survival, heartbreak and hope through the eyes of a child refugee.

Download the free app at Google Play and Apple Store and begin walking. There are six chapters narrated by Chan that hop between the story her grandmother used to tell her on their walks and the present day, where Chan begins to piece together clues that reveal what happened to her grandmother during Japan's siege in China during World War II.

The storytelling app connects to your device's pedometer and only plays when you're walking. If you stop, it will prompt you to keep going — so if you're at a stoplight or taking a break, don't worry: the app will pause for you, or you can simply hit pause yourself at any time.

Eighty Thousand Steps also has an Accessibility Mode that you can enable if you want to just listen to the story.

Now available for download on Google Play and Apple Store.
