The round trip

  1. Your student films and sends

    From the cast in the app, as a file through Messages, Mail, WhatsApp or AirDrop.

  2. You open it in Tight Loop

    The clip arrives with the rod tip path and what the app saw already on it.

  3. Draw and talk

    Pen, arrow, circle, reference line or angle, and a voice note. The video scrubs with your voice.

  4. Send it back

    The same way it came. No accounts and no server: the file goes only where you send it.

Your instructor card

A QR code your students scan to add you. Your name, and your certification if you add it, appear on their cards.

Exam prep for candidates

The FFI Certified Instructor casting tasks as a checklist, each with a video of yourself and its trace to send to a mentor.

The task wording is paraphrased. The official FFI material is the reference.

Get listed

The app has no instructor directory yet. Students add their instructor by name, or by scanning the QR code on the instructor card. A directory will list only instructors who ask to be in it. Ask now and tell us your body, certification level, languages, area, and whether you review clips remotely.

Free for instructors, from the first clip.

In the app: You › Instructor mode.

Coming soon to the App Store and Google Play
