Your studio's teaching deserves a home
Barre sequences live in one teacher's rehearsal pianist's head. French ballet terms get explained again to every new student. The RAD or ISTD syllabus sits in a binder in the office. C3NTR is a quiet place to write it all down once, in your studio's voice.
Who this is for
Studios with multiple teachers
Two or more teachers, several classes a week. C3NTR holds the shared standard so every class draws from the same library.
Schools preparing for vocational training
You're training dancers for upper school auditions. Content locked by grade keeps younger students on foundations while pre-vocational dancers see the full vocabulary.
Built for teachers, not for IT
Your teacher opens the app, taps Edit, and writes the next enchaînement breakdown in plain prose. The next class, dancers read it before warm-up.
Write directly in the app
Like a notepad. New articles are drafts until you publish, so nothing goes live by mistake.
Mobile-first authoring
Edit on the phone between classes or on the way home. The same library, the same edit screen.
A working library in under an hour
Import the starter template in a few taps. Edit anything that doesn't fit. Publish when ready.
RAD grades, ISTD grades or your studio's progression
Content locked by level, in your studio's progression
Tag any article with a minimum level. Pre-primary dancers see only foundations. Intermediate Foundation sees more. Advanced students see everything. The same library, the right view per dancer.
A glossary in French and English
Ballet's language is part of the practice. C3NTR's glossary holds the terms in one place: the French, your studio's translation, and the article each term appears in.
- Barre
- The barre, the horizontal rail used for support during the first half of every ballet class..
- The five positions

Exam dates, end-of-year shows, summer school
C3NTR isn't only the library. Schedule RAD exam dates, post when a guest teacher is taking class, and let dancers see the term ahead. Announcements land on their Today tab and events sit on the calendar.

Common questions
Can dancers only see their level's material?
Yes. Tag any article with a minimum level. Beginners see only what's appropriate for them. Teachers and senior students see everything.
Does it cover Vaganova, Cecchetti, Bournonville, RAD?
C3NTR is style neutral. The library is yours to fill. Vaganova, Cecchetti, Bournonville or another tradition. Write in your studio's voice.
Can my studio customise the ballet template?
Yes. Every article, step and term is editable. Add your style's vocabulary, your syllabus and your studio's standards. The template is a structure, not a script.
How long does it take to set up?
Most schools have a working library in under an hour. Import the starter template in a few taps, then edit anything that doesn't fit. Starting blank takes a little longer. Allow an hour or two to write your first ten articles. Students can use the app the day you publish.
Do I have to stop using my booking system?
No. C3NTR is a knowledge library for your curriculum, terminology and progressions. Booking, billing and scheduling stay with the tools you already use.
Is there a free plan?
Yes. Seed is free forever for up to 30 students, with no credit card required. Move up to School (£39/mo) or Academy (£69/mo) when you outgrow it.
