Your studio's teaching deserves a home
The primary series gets practised before sunrise. Sanskrit names, vinyasa counts and drishti points blur for new students. The traditions of Mysore-style practice rarely make it onto the page. 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 teacher draws from the same library, with your studio's voice on every page.
Teacher training programmes
You're training the next generation of teachers. C3NTR holds the curriculum your trainees read: the philosophy, the asana library, the sequencing. Open to them from week one and theirs for life.
Built for teachers, not for IT
Your teacher opens the app, taps Edit, and writes the next pose breakdown in plain prose. The next Mysore morning, students arrive knowing the 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.
Primary, Intermediate and Advanced series (or your studio's progression)
Content locked by level, in your studio's progression
Tag any article with a minimum level. Beginners see the standing sequence. Intermediate see the seated postures and finishing. Advanced see second series. The same library, the right view per student.
A glossary in Sanskrit and English
Ashtanga yoga's language is part of the practice. C3NTR's glossary holds the terms in one place: the Sanskrit, your studio's translation, and the article each term appears in.
- Vinyasa
- The system of linking breath to movement that carries you through the Ashtanga sequence..
- Ujjayi
- The breathing technique used throughout the Ashtanga practice, nasal, slightly constricted at the throat, slow and audible.
- Bandha
- A muscular and energetic engagement held through most of the Ashtanga practice..
- Drishti
- The fixed gaze point used in each posture of the Ashtanga sequence. Every posture has its own prescribed drishti.
- Surya Namaskar
- Sun salutation, the opening sequence of the Ashtanga practice, done before any postures. There are two versions: A and B.
- Asana
- A posture or physical shape, the forms that make up the Primary Series. In the Ashtanga system, each asana has a prescribed entry, hold, and exit.
Mysore mornings, intensives, teacher training
C3NTR isn't only the library. Schedule the next intensive, post when a visiting teacher is on, 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 (an asana, a pranayama practice, a philosophy note) with a minimum level. Beginners see only what's appropriate. Teachers and senior students see everything.
Does it cover Sri K. Pattabhi Jois, Sharath Jois, Manju Jois?
C3NTR is lineage neutral. The library is yours to fill: Sri K. Pattabhi Jois, Sharath Jois, Manju Jois or your own teacher's transmission. Write in your studio's voice.
Can my studio customise the ashtanga yoga template?
Yes. Every pose, breath practice and term is editable. Add your studio's sequencing, your cueing language and your philosophy emphasis.
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.
