Take the next step toward evolution.

Nanobeasts is a step counter that makes every walk count. Your steps go toward your daily goal, your stats and your Nanobeast, a creature that hatches and evolves as you walk.

No account needed. Works with Apple Health. Includes an Apple Watch app.

Walk like you normally do.

Nanobeasts counts your steps automatically with Apple Health or your iPhone's motion sensor. No logging, no buttons, no chores. Just walk.

  1. Hit your goal

    Watch today's steps climb toward your goal. Every step also counts toward your Nanobeast's next stage.

  2. Hatch an egg

    Every egg has a step goal. Reach it and out comes a brand new Nanobeast.

  3. Grow your Nanobeast

    Keep walking and it evolves into its next form, unlocking a new entry in your Dex.

Drag to walk. See what evolves.

Add steps with the slider and see a Nanobeast grow from egg to final form. Each stage has its own step goal.

Pick your next egg.

When your Nanobeast is fully grown, three new eggs arrive. What's inside stays a secret until it hatches, and any steps you take while you decide still count.

Frequently asked questions

When does Nanobeasts launch?

Soon. Nanobeasts is getting ready for release on the App Store for iPhone and Apple Watch. This page will link straight to the download as soon as it's live.

What do the Nanobeasts do?

They grow with your steps. Eggs hatch and Nanobeasts evolve when you reach step goals, and every one you discover is added to your Dex. All it takes is walking.

Do I need an Apple Watch?

No. Your iPhone counts steps on its own. The Apple Watch app is a bonus for checking progress and recording walks from your wrist.

Do I have to connect Apple Health?

It's optional. Without it, Nanobeasts uses your iPhone's built-in step counter. Connecting Apple Health gives more complete tracking, including steps from your Apple Watch.

Do steps from before I install count?

Your past step history shows up in Stats, but only steps you take after you start count toward hatching, evolving and badges.

Do I need an account?

No. There's no sign-up. Your Nanobeasts and progress are saved on your device.

Is it on Android?

Not right now. Nanobeasts is built for iPhone and Apple Watch.

How much does it cost?

Nanobeasts Pro is $29.99 a year with a 7-day free trial, or $4.99 a month. Both include everything.

Your first egg is waiting.
