Your school's craft deserves a home
Aerial progressions get demonstrated and corrected in air. Safety responsibilities of the rigging and spotter blur between sessions. Conditioning blocks live in the coach's head. C3NTR is a quiet place to write it all down once, in your school's voice.
Who this is for
Schools 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 training performers
You train students toward performance careers. Content locked by level keeps newer students safe on conditioning while pre-pro see act creation.
Built for teachers, not for IT
Your teacher opens the app, taps Edit, and writes the next aerial sequence in plain prose. The next session, students arrive knowing the safety cue.
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.
Levels, beginner, intermediate, advanced, performer
Content locked by level, in your school's progression
Tag any article with a minimum level. Beginners see conditioning and basic shapes. Intermediate see drops and transitions. Performer level sees act creation. The same library, the right view per student.
A glossary of circus arts terminology
Circus arts carries its own vocabulary. C3NTR's glossary holds the terms in one place: the technical names, your school's translation, and the article each term appears in.
- Tissu
- The French word for fabric or tissue, used in circus training to refer to aerial silks..
- Lyra
- The Italian word for lyre, used to describe the aerial hoop, a steel ring suspended from one or two rigging points. Also called "aerial hoop" in English-speaking schools.
- Rigging
- The system of hardware, rope, and attachment points used to suspend aerial apparatus safely from a ceiling or purpose-built frame.
- Dead hang
- A static hanging position with arms straight, body hanging directly below the grip point, and no momentum.
- Inversion
- Any position in which the hips are above the head.
- Cascade
- The foundational three-ball juggling pattern, in which each ball follows an arc from one hand to the other in a continuous cycle.
Shows, training intensives, safety reviews
C3NTR isn't only the library. Schedule the next show, post intensive dates, and let students see what's ahead. Announcements land on their Today tab and events sit on the calendar.

Common questions
Can students only see their level's material?
Yes. Tag any article with a minimum level. New students see only foundations. Teachers see everything.
Does it cover ENC, Cirque du Soleil pathway, your school's method?
Yes. The starter is method neutral. ENC, Cirque du Soleil pathway, your school's method can adapt the curriculum without rewriting.
Can my school customise the circus arts template?
Yes. Every article, exercise and tag is editable. Add your school's repertoire, your favoured methods and your house standards.
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.
