Built by a yoga teacher, for yoga teachers
The story behind Sequence/OS
Sequence/OS was built by Liz, a working yoga teacher, for other yoga teachers. It was not designed by a software company that picked yoga as a market. It was made by someone who was planning classes every week and could not find a tool that thought the way a teacher thinks.

Liz, yoga teacher since 2020
I've been teaching yoga since 2020, passionate about creating an inclusive, safe space for all bodies to practice. I also have an operational background and a logic-centric brain - I'm always looking for ways to make processes and tasks easier.
My love of sequencing spilled into notebook after notebook. I'm almost incapable of teaching the same class the same way twice, which meant scrappy notes scattered across the teaching room floor, loved classes I could never quite find again, and a constant, distracting eye on a notebook mid-practice instead of actually feeling how the class flowed.
I figured I couldn't be the only teacher struggling with this, there had to be a better way. That thought became Sequence/OS.
It's not AI class generation, and it's not an overwhelming pose list. It's built to let you be the teacher you already are - to keep the craft alive - while making the day-to-day of teaching a whole lot easier.
Where it came from
Class plans lived in notebooks: scribbled arcs, arrows, a peak pose circled twice, timings guessed in the margin. The good ones got lost. The ones that survived were hard to reuse, impossible to share, and never quite matched what actually happened in the room.
There was no single place to hold the craft: the poses, the cues, the music, the calendar of who was being taught what and when. Sequence/OS started as that place, and then kept growing every time a real class exposed something missing.
What being a teacher changed
- Pose notes written from the teaching seat: alignment cues, what usually goes wrong in a real room, and the modifications you actually reach for, rather than encyclopaedia copy.
- Voiceover cues that sound like a person: the spoken cue is the sentence a teacher would say out loud, not a label read aloud by a machine.
- Play Mode designed for a phone on the floor: large type, high contrast, side prompts for left and right, and view options for when your eyes are three metres away from the screen.
- Timing that suits the style: a 90-second Yin hold and a five-breath Warrior II are both first-class citizens, because both get taught.
- Repeat groups and mini-sequences: teachers repeat things, twice on each side, a warm-up they always use. Those exist because class prep works that way, not because they made a neat feature list.
- Class memory: the reflection prompt after a class, and the reminder next time you teach it, came straight from forgetting that a sequence ran ten minutes long.
What we deliberately did not build
Sequence/OS does not generate your class. It would have been the easier product to build and the easier one to market, and it would have quietly taken the most valuable part of teaching away from you. The tools speed up the work around sequencing; the sequencing itself stays yours. More on that in why Sequence/OS is not an AI class generator.
Still teaching
The app keeps changing because it is still used in real classes every week. When something is awkward with a phone on the mat, or a cue reads badly out loud, it gets fixed. That is the whole advantage of being built by someone who has to teach with it on Tuesday.
Questions, answered
- Who built Sequence/OS?
- Sequence/OS was built by Liz, a working yoga teacher, for other yoga teachers. It started as a way to stop losing class plans in notebooks and grew into the tool she now uses to plan and teach her own classes.
- Is Sequence/OS made by a yoga teacher?
- Yes. It is designed and written by a teacher who is still teaching, not by a software company adapting a generic planning tool for yoga. The pose notes, cues and timings come from real class prep and real rooms.
- Does that change how the app works?
- It changes the details. Cues are written the way a teacher would actually say them, timing suits a 90-second Yin hold as well as a five-breath Warrior II, Play Mode is designed to be read from a phone on the floor, and repeat groups and mini-sequences exist because that is how teachers really build classes.
- Does Sequence/OS generate classes for you?
- No. Sequencing decisions stay with the teacher. Inspire Me offers an outline when you are stuck, but it never writes the class for you.
