Understanding before speed

Pictures first in Multiplication. A meaning, a sound and an example for every word.

Three subjects. One calm way to practise
Each app teaches one thing, carefully. They share a family account, a look and a way of being kind about mistakes.
Vocabulary
by Cylin
A daily word journey that grows with your child, from first words to SAT.
- A short word game finds the starting point, then each day blends new words, review and practice on the tricky ones.
- Pictures and sound for the youngest; roots, shades of meaning and exam vocabulary for older students.
- No timers, no streaks to protect, no leaderboards. A wrong answer gets the right one and an example.
Multiplicationby Cylin
Times tables that make sense first, then stick.
- Every fact starts as a picture: 7 × 8 is seven rows of eight dots you can count.
- A strategy for each fact, then short, spaced practice until the answer comes in seconds.
- All 144 facts in one grid, from 1 × 1 to 12 × 12, filling in as they’re learned.
Piano Sight Reading
by Cylin
Your piano becomes the game controller.
- A note appears on the staff. Your child plays it on a real piano, and Pip jumps the log or opens the chest.
- Six worlds, 24 levels, from Middle C to both clefs, ledger lines, sharps and flats.
- A Songbook of public-domain songs, and pages from your own lesson book, photographed and turned into levels.
- Microphone
- USB MIDI
- Computer keys
One account. Every app. Each child’s own progress
- Step 1
Set up your family in Cylin Hub
Add each child once, with a first name or nickname and a colour. Children never need an email or a password.
- Step 2
Children pick their name and practise
On any computer or tablet where you’re signed in, each child taps their name in any Cylin app.
- Step 3
See the week in one place
Minutes practised, by child and by app. Progress follows them from the laptop to the tablet.
How every Cylin app teaches
Six rules that come from how memory and motivation work, not from what keeps a child on a screen longest.
Short on purpose
Sessions are sized so a child finishes wanting one more, not needing a break.
A piano level: 2–4 minutes. A multiplication session: about 3.
Practice that adapts
Every note, fact and word is tracked on its own, and the ones that need it come back sooner.
Spaced review, mixed practice and contrast pairs.
Help that fades
Hints appear when a child is stuck and step back as they improve.
Letter names, keyboard diagrams and dot pictures fade on their own.
Mistakes without shame
No buzzers, no red crosses, no lost streaks. Feedback says what happened and what to try.
“Not quite. 10 × 6 is 60. That’s a useful one to see.”
Rewards that serve the skill
Stickers, hats for Pip and a filling progress grid celebrate real learning.
Nothing is for sale inside the apps.

Questions from parents
Something else? Email support@cylin.app.
How do my children start?
Create a family account at hub.cylin.app and add your children. On any tablet or computer where you’re signed in, they open any Cylin app and pick their name. They never need their own accounts or passwords.
What devices do the apps run on?
All three run in a current browser on a computer or tablet: Chrome, Edge, Safari and Firefox. Vocabulary and Multiplication also work well on phones. USB MIDI in Piano Sight Reading needs Chrome or Edge.
Do we need a real piano?
Any acoustic or digital piano or keyboard works, heard through the device’s microphone. No piano nearby? The computer keyboard works as one too.
Can siblings share a device?
Yes. Each child has their own name, colour and progress in every app.
What do you collect about my child?
Only what the apps need: your email for the family account, your children’s first names or nicknames, and their progress and practice time, plus simple records of what happened in an app (a lesson finished, an error) that we use to fix problems. No ads, and nothing goes to third-party trackers.
Were these apps called something else?
Yes. Vocabulary was Lexcursion, Multiplication was Dotwise and Piano Sight Reading was Keybound. Same apps, same addresses, and your children’s progress is all still there.
