Your studio's teaching deserves a home
Lindy basics get called out on the floor but rarely written down. Step names blur for new students. The history, Savoy Ballroom, Frankie Manning, the swing revival, sits in conversation. 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.
Studios with a social scene
Your studio runs weekly socials and exchanges. Content locked by level keeps newer dancers confident on basics while advanced dancers prepare jam moves.
Built for teachers, not for IT
Your teacher opens the app, taps Edit, and writes the next turn pattern breakdown in plain prose. The next social, dancers know the lead before they dance it.
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
Content locked by level, in your studio's progression
Tag any article with a minimum level. Beginner sees basics and timing. Intermediate sees turn patterns and Charleston. Advanced sees solo jazz and jam moves. The same library, the right view per dancer.
A glossary in English and English
Swing's language is part of the practice. C3NTR's glossary holds the terms in one place: the English, your studio's translation, and the article each term appears in.
- Triple step
- A triple step is three quick steps danced in the space of two beats, "tri-ple-step," or "1-and-2." It is a building block of much swing dancing..
- Rock step
- A rock step..
- The pulse
- The pulse is the gentle..
- Lead and follow
- Lead and follow are swing's two roles..
- Frame
- The frame..
- Swingout
- The swingout is the signature move of Lindy Hop, a flowing eight-count figure where the partners move apart and come back together..
Socials, exchanges, showcases
C3NTR isn't only the library. Schedule the weekly social, post when an exchange is coming up, and let dancers see what's 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 Lindy Hop, Charleston, Balboa, Collegiate Shag, Solo Jazz?
C3NTR is style neutral. The library is yours to fill. Lindy Hop, Charleston, Balboa or another tradition. Write in your studio's voice.
Can my studio customise the swing 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.
