Step Tomo · iPhone & Apple Watch
ステップトモ · tomo (友) means friend
A small egg is waiting for you. Take it for a walk and it hatches. Keep walking, and your new friend grows a little every day, along the rice terraces, under red torii and over a little wooden bridge.
Works with Apple Health · iOS 18 and watchOS 11 or later

How it works
Nothing new to learn. The steps you already take become something small and alive to care for.
Every step counts, from your pocket or your wrist. Each one helps your friend grow a little.
Your friend lives on your steps: peckish when the day has been still, happy when you're on your way, round and content when you reach your goal.
Day by day it grows, into a second form and then a third, while your good days gather in the calendar.
Who's in there?
Your first egg is already waiting. Take a short walk together and listen for the crack. Who's inside is a surprise until it hatches.
Later, you can choose a new egg and keep it warm with three days of walking. Every egg holds a small chance of something rare.
The pets
Each friend has its own little heart, and each one grows through three stages.

The grower
A sprout who unfurls a new leaf on every walk, and blooms at full size.

A little flame who loves a brisk pace, and glows brighter as you go.

A patient traveller who gathers trail gear as the miles add up.

The climber
A round blue bird who loves stairs and hills, and one day learns to fly.
Fluff → Fledgling → Soarer

The pup
A tiny cowlicked puppy who grows into Ranger, bandana and all.
Pup → Tracker → Ranger
Egg to stage 3, for every pet.
A home of its own
Your friend lives in a little wooden house, with a bonsai by the window and a red donut bed up in the loft. Outside, a cherry tree leans over a stone lantern, and a koi pond spills over a waterfall at the island's edge.
It climbs the stairs to sleep and waits by its bowl when it's hungry. The sky keeps time with your day: blue mornings, a rosy dusk, then stars and glowing lanterns.

Walks
Choose a time, a step goal or simply wander. Your friend trots beside you along a winding stone path: under torii gates, down a cherry-blossom avenue, past bamboo, rice terraces and a hillside shrine, over little bridges and out to a lake beneath the mountain.
Other walkers' pets pass you on the way. And tucked in the grass there are little finds: acorns, pinecones, cherry petals and, once in a while, a blue feather.




Apple Watch
Lift your wrist and there it is, waving hello. Tap it and it hops or cheers. It lets you know when it's peckish, and curls up to sleep at night. Today's steps and your streak are always a glance away.

Set a goal with the Digital Crown and head out. Your friend walks toward you across a little meadow while your steps and heart rate tick along.
Walks from the watch are saved as walking workouts, so they count toward your rings.
Keep your friend on your watch face and in the Smart Stack, with its mood and your progress.

FAQ
It reads your steps from Apple Health, which already brings your iPhone and Apple Watch together, and counts live steps while you walk. Your Health data stays on your devices.
Who's inside your first egg is a surprise until it hatches: Sprig, Kindle, Trundle, Puff or Scout. Later you can pick the egg you'd like for 2,000 coins.
No. Step Tomo works on iPhone alone. With an Apple Watch your pet also lives on your wrist, in complications and in the Smart Stack, and you can start walks from the watch.
Your friend gets peckish, never sick. A short walk perks it right up, and nothing you've grown together is taken away.
Yes. Your Health data and walk routes never leave your devices. We keep a small backup of your pets and progress under an anonymous ID, so a reinstall brings them back, and your email only if you sign up for news. Privacy policy.
Soon, on the App Store for iPhone and Apple Watch. Questions in the meantime? Get in touch.
