KeyStage

Founding Families

Lifetime access, for the first 20 families.

KeyStage is a real piano curriculum on your iPad. Before it launches to everyone at $99 a year, I'm inviting 20 founding families in for a one-time $50.

A child's hand plays a MIDI keyboard while KeyStage on an iPad shows the same music as falling notes.

I'm a professional pianist and composer, and a dad of four. Every music app I tried with my own kids was a game with colored lights. They tapped along, collected stars, and still couldn't read a line of music or sit down at a real piano and play. So I built the thing I couldn't find: a curriculum that teaches reading, rhythm, and ear training the way a teacher does.

What you'll need

Where it stands, honestly

The app is built and working: the full practice engine, twelve curriculum levels, rhythm and ear-training gyms, the parent dashboard, and sync across iPads. Family beta starts this fall through Apple's TestFlight. Founding families are first in, and what you tell me shapes what ships.

Questions

Does my keyboard work?
If it has USB or Bluetooth MIDI, yes. Almost every keyboard made in the last twenty years does. The keyboard guide has specifics.
What does lifetime mean?
Your household's subscription, free, for as long as KeyStage exists. Not per child: the whole family, up to 8 profiles.
When do I get access?
Beta invitations go out by email this fall. You'll hear from me personally.
What if it's not for us?
Tell me and I'll refund the $50 in full. No questions, no hard feelings.
Is it safe for kids?
No ads, no chat, no microphone, no external links in kid-facing screens. Here's the privacy policy, in plain language.
