OuterPractice for teachers is an asynchronous review tool: a student exports a session file from a home practice, the teacher opens it, pins comments to specific events on the timeline, and sends the file back. No accounts, no cloud, no scheduling.

For teachers

The lesson loop, between lessons.

Your student practices at home, exports a session, you annotate it, send it back. No accounts. No scheduling. No cloud.

01 · How it runs

How a lesson loop runs.

Two people, two file exchanges, nothing in between. The session file is a plain JSON — no video, no audio — that travels however you already share files.

studentteachersession file →← annotated file

1 · Practise

The student practises and exports a session file when they're done.

2 · Open

You open the file in your browser. No install, no account, no login.

3 · Annotate

Pin written comments to specific events on the timeline.

4 · Send back

The file returns to the student. The conversation continues, asynchronously.

02 · The file

What the student gives you.

Every imported session carries the body-state data — and nothing that could identify the room it was recorded in.

Inside the file

  • Pose data per second — shoulder rise, head tilt, torso angle
  • Facial-tension markers — jaw, brow, blink rate
  • Ambient-audio features — onset jitter, dynamic events
  • Pre/post body-state sliders — the student's own rating

Never in the file

  • No video frames
  • No raw audio
  • No identity, account, or location
  • Nothing that travels through a server
03 · What it isn't

What it isn't.

  • Not a substitute for in-person lessons. It is the between-lesson layer.
  • Not a video review tool. It is a body-state review tool — no video persists.
  • Not a student-management system. No rosters, no scheduling, no billing.
04 · Questions

Teacher questions.

Does this replace in-person lessons?

No. It's the between-lesson layer. The live observation that an in-person lesson provides is irreplaceable; OuterPractice covers what happens at home in between.

How do session files reach me?

However you and the student already share files — email, cloud drive, AirDrop, USB. There is no server in between. The file is a JSON export.

Can I annotate while watching the student practice live?

No. v2 is asynchronous only. Live observation is what an in-person lesson already provides.

What if two teachers annotate the same session?

Last import wins on the student's device. v2 does not yet resolve concurrent edits — surface a limit, document it, plan to address if needed.

Is it free?

A free tier lets you import up to 3 sessions and annotate freely. Beyond that, full teacher mode is €149 once.

How much does it cost?

€149 once, lifetime for v1.x. Full teacher mode with unlimited imported sessions. 30-day money-back. See pricing for details.
