- The page says it reviews 33 technique aspects across 17 jump types; its planned Pro tier is not yet available.
Field notes
The recording instructions specify a fixed phone, a side view, and a clip beginning three to four steps before takeoff. The site says unsuitable footage, such as dark video or feet outside the frame, will not be assessed and does not count against the free analyses. Its example feedback includes measured support time and arm timing; the paid Pro tier is presented as a future option.
