Arcelta measures body angles in videos and photos so you can compare them. It works for any activity.
🚨 Please put “Arcelta” in the subject line. This address is shared across several apps, so without the app name we cannot tell which one you are writing about, and the reply will be slower.
Sending from Settings → Contact inside the app fills in the subject and your device details for you.
A reply may take a few days. Including the following helps a lot:
If the person is too small, the scene is dark, or only part of the body is visible, nothing can be found. Try filming in good light with the whole body in frame, as large as possible. If a single frame fails, stepping to another frame often works.
On the result screen, tap “…” → “Choose subject again”, then tap the person you want. Tracking continues forwards and backwards from there. When people overlap, tracking can jump to someone else, so pick a frame where they are clearly separated.
Left/right assignment is decided when you import (the “Is left/right correct?” step under the preview). Facing away from the camera or sideways can confuse it, so check that the “R” marker sits on the person’s right side. It cannot be changed after analysis — re-import if it is wrong.
Yes. Your analyses and footage are stored inside the app on your device, so they carry over with Quick Start (device-to-device transfer) or when you restore from a backup. There is no cloud sync, so the same data cannot be used on two devices at once, and deleting the app deletes it.
