Your studio's teaching deserves a home
MBSR and MBCT protocols get adapted for each cohort and the variations get lost. Reading lists sit across folders. Home practice instructions live in the teacher's notes. 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.
Teacher training programmes
You're training the next generation of teachers. C3NTR holds the curriculum your trainees read: the practices, the philosophy, the lineage.
Built for teachers, not for IT
Your teacher opens the app, taps Edit, and writes the next practice note in plain prose. The next class, students arrive knowing the practice.
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, MBSR / MBCT graduate, teacher training
Content locked by level, in your studio's progression
Tag any article with a minimum level. Beginners see foundations. MBSR / MBCT graduates see deeper practices. Trainees see facilitation. The same library, the right view per student.
A glossary of mindfulness terminology
Mindfulness carries its own language. C3NTR's glossary holds the terms in one place: the names, your studio's translation, and the article each term appears in.
- Mindfulness
- A quality of attention, clear, present, friendly, directed toward what is actually happening in a given moment.
- Sati
- The Pali word that "mindfulness" was originally translated from, closer in meaning to "remembering" or "recollection" than to "attention" alone.
- Body scan
- A formal practice in which attention is moved slowly through the body, region by region, noticing whatever sensations are present without trying to change them.
- MBSR
- Mindfulness-Based Stress Reduction, an eight-week, evidence-based mindfulness programme developed by Jon Kabat-Zinn at the University of Massachusetts in 1979.
- Beginner's mind
- The quality of meeting an experience as if for the first time, without the layer of assumptions, opinions, and predictions that ordinary familiarity brings.
- Mindful pause
- A short, deliberate break in ordinary activity, usually three breaths or sixty seconds, used to interrupt automatic reaction and return attention to the present.
MBSR / MBCT courses, retreats, teacher training
C3NTR isn't only the library. Schedule the next MBSR course, post retreat 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. Beginners see only foundations. Teachers and senior students see everything.
Does it cover MBSR (Kabat-Zinn), MBCT, secular mindfulness?
C3NTR is lineage neutral. The library is yours to fill: MBSR (Kabat-Zinn), MBCT, secular mindfulness or your own teacher's transmission.
Can my studio customise the mindfulness template?
Yes. Every article, practice and term is editable. Add your studio's sequencing, your cueing language and your tradition.
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.
