Yours to keep
Saved on your phone, separate from every other app.
Meet Mii
A universe you can create.
Talk to Mii, your companion, and turn ideas into real apps and games that live on your phone. No code. Just you and your imagination.
Chapter 1 · Say it your way
Ideas start as conversations.
Describe it the way you would to a friend: a photo journal for your trips, a study timer, a tiny garden game for your niece.
A photo journal. I pick photos, add a caption, and it's all there when I come back.
Love it. I'll keep your photos and captions on your phone. Want a date on each entry?
Chapter 2 · Plan together
Mii plans with you, not for you.
Before anything is built, Mii shows a short plan: what it will make, what it needs, and a few choices you can skip. Nothing hidden, nothing surprising.

Chapter 3 · Built and tested
Built, tested, ready.
Mii writes your app, tries every tap in a real browser on two phone sizes, fixes what it finds, and only hands you a version that passed.
- 1 Writes the app from your plan
- 2 Tests what you asked for, tap by tap
- 3 Repairs anything that broke
- 4 Gives you a version that works — and listens if you add a thought mid-build
Chapter 4 · Your universe
Every idea becomes a world.
Your creations live together in My Apps. Change any of them whenever you like; every version is kept.
Always improvable
Ask for a change and Mii builds the next version from the latest one.
Safe by design
Creations can't reach the internet or each other's data.
Chapter 5 · A companion who knows your world
Ask Mii anything about your things.
How heavy did I lift last week? Why is my game blank? Mii finds the right app, reads what it needs on your phone, and answers — only with your permission.
Why did Lift Log go blank?
It tried to read a weight that wasn't saved yet. Want me to fix it?
Chapter 6 · Wherever you are
One universe, every screen.
Each creation is made once. It runs on your phone today, in your browser next, and on your desktop after that.
