Routines
Routines in your key, at your pace
KeyFu is a piano practice app for iPhone and iPad. Its routines are sets of exercises in a fixed order, played on your digital piano or MIDI keyboard.
Play a ready-made routine for free, save one as your own, or build your own with KeyFu Pro.
Practice with purpose. Play with freedom.
What adapts, and what you choose
KeyFu adapts to you
- A ready-made routine plays in today’s key: the coach’s pick, or the one you set.
- Anything you haven’t played in that key yet starts a little slower, and the coach says why.
- The tempo follows how you play, shown as your pace.
- Each exercise is checked against how you are doing before it starts.
You choose
- Any ready-made routine, or one exercise from it on its own.
- Save a ready-made routine as yours, and it keeps the day’s key as its own.
- With Pro, your own routines: the exercises, their order, key, tempo and rounds.
- Twice through for one run, and a mixed order on a routine you built.
- Which routines to pin, and which to delete.
Ready-made
Start any ready-made routine, free
played in today’s key · saved copies keep theirs
KeyFu puts ready-made routines together from its own exercises, and every one of them is free to play.
A routine’s page shows how long it takes, a summary and its exercises. Tap one to play it alone, or Practice routine to play them all as one session.
It plays in today’s key. Anything you haven’t played in that key yet starts a little slower, and the coach says why.
Each exercise shows its tempo as a dot on a slow-to-fast line, with no number. The words beside it say the rest, such as your pace or easing in.
Save as my routine copies it into Your routines, where it keeps the day’s key as its own. Saving a copy is free.
Your own
Build your own routine with KeyFu Pro
today’s key · always in G · your pace · always this pace
Give it a name, add exercises, and drag them into the order you want.
Add exercises opens every exercise that can go in a routine, Ready for you first. Search or filter, pick as many as you like, and add them in one go.
It keeps its own key, starting from today’s, and each exercise you add joins it. Any exercise can follow today’s key instead, or stay in another key you pick.
Its tempo follows your playing and can move up as you play it cleanly. Or set one tempo that stays, written as a number.
Set how many rounds each exercise plays. Edit changes a routine any time, and pressing and holding its card pins or deletes it.
From your coach
Let the coach build one for you
Tell the coach in the chat what you are after, and he can build a routine from the app’s own exercises.
Its card is marked BUILT BY COACH and says why he picked it. Why opens his reasons, one by one.
If the coach can’t be reached, the app builds the plan straight from your measured practice instead, marked INSTANT · FROM YOUR DATA.
Starting one is open to everyone. Changing it is part of Pro, and makes it yours after the app asks first.
Before each exercise
It checks how you are doing before each exercise
Practice routine plays a routine like today’s plan: each exercise is checked against how you are doing before it starts.
If it looks like too much, Let’s ease off says why: swap in something lighter when there is one, carry on, or take a break.
In a routine, a break ends the run, and it isn’t kept for later.

Common questions
Are the ready-made routines free?
Yes, anyone can play any ready-made routine and save a copy of it. Building and editing your own routines is part of KeyFu Pro.
Can I choose the key a routine plays in?
A ready-made routine plays in today’s key, which you can set. In one you build, each exercise keeps the routine’s key, follows today’s, or stays in a key you pick.
How is the tempo set in a routine?
A routine’s tempo follows how you play, shown as a dot on a slow-to-fast line with no number. In a routine you build, you can also set a fixed tempo.
What happens if I get tired in the middle of a routine?
The app checks how you are doing before each exercise and says so if it’s too much. It offers a lighter swap when one exists; a break ends the routine.
Can the coach make a routine for me?
Yes, ask in the chat and he can build one from the app’s exercises.
