Your gym's tradition deserves a home
Padwork combinations vary by trainer. Thai terminology gets a quick explanation mid-round. The Wai Khru is something most students half-know. C3NTR is a quiet place to write it all down once.
Who this is for
Gyms with multiple trainers
Several trainers across the week. C3NTR holds the shared standard so every padwork session draws from the same library.
Fight teams
You're prepping fighters under traditional rules, K-1 or both. Content locked by level keeps newer members safe while comp fighters see the deeper game.
Built for teachers, not for IT
Your kru opens the app, taps Edit, and writes the next clinch sequence in plain prose. The next pad session, members arrive knowing the entries.
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.
Prajiad (armband) levels, amateur or pro tiers
Content locked by level, in your gym's progression
Tag any article with a minimum level. New members see the eight limbs and basics. Intermediate see clinch and combinations. Fighters see the full game.
A glossary in Thai and English
Muay Thai's language is part of the art. C3NTR's glossary holds the terms in one place: the Thai, your gym's translation, and the article each term appears in.
- Wai kru ram muay
- The pre-bout ceremonial dance that honours the practitioner's teacher..
- Mongkol
- The braided headband worn during the wai kru ram muay and removed just before competition begins..
- Kru
- Teacher..
- Nak muay
- A Muay Thai practitioner..
- Teep
- The push kick, Muay Thai's longest weapon and its most versatile defensive tool..
- Jab
- The straight punch from your lead hand. Fast, light, constantly used, a Muay Thai practitioner's main tool for finding range, setting tempo, and opening up combinations.
Fight nights, gradings, seminars
C3NTR isn't only the library. Schedule the next fight night, post grading dates, and tell the gym when a visiting kru is teaching. Announcements land on their Today tab and events sit on the calendar.
Start from our Muay Thai template

Common questions
Can students only see their level's material?
Yes. Tag any article with a minimum level. New members see the eight limbs and basics. Krus always see everything.
Is the Wai Khru and traditional ceremony covered?
Yes. The starter includes articles on Wai Khru Ram Muay, the Mongkol and Prajiad, and the role of the Sarama, written with respect for the tradition.
Can my gym customise the Muay Thai template?
Yes. Every article, combination and term is editable. Add your camp's lineage, your favoured combinations and your local rule set.
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.
