Description by Mark Fitzgerald(from the App Store)
Core by RTI is now CORE by Stay Sharp. It's the same library under a new name, and existing subscriptions carry over.
CORE is a figure skating reference organised the way skating is taught. Open an area, pick the element and watch it done properly. There are no feeds and no shopping, just the reference.
SIX AREAS • Singles: every jump with Mike Weiss, spins from basics to Level 4 features, Dartfish jump analysis with Ben Ferreira, and IJS in 30 seconds • Skating Skills: the Skating Skills tests (formerly Moves in the Field) level by level, with a demonstration of every move in the pattern • Solo Dance: solo pattern dances and dance elements, tutorials first, with the pattern diagrams alongside • Partner Dance: partner pattern dances, demonstrated, with the pattern documents for each dance • Dance Music: music for the pattern dances, track by track, ready for practice • Rules & documents: rulebooks, test sheets and pattern documents you can open at the rink
Also in CORE: Club Finder, with skating clubs across the U.S. listed state by state.
NEW: CORE AI Ask a question about a rule or element in plain words. CORE AI answers from the official handbooks and CORE videos, and every answer shows where it came from. Tap to open the handbook page or play the video. If the sources don't cover your question, CORE AI says so. CORE AI is a study aid; for competition decisions, check the current rulebook and your officials.
NEW: SEARCH Find any element in seconds across every demonstration, tutorial and document. Searching "moves in the field" finds Skating Skills too.
NEW: MAC AND APPLE TV • Mac: the whole library in a sidebar, with Search (⌘F) and Resume, plus a jump view with rotation, camera angle and playback speed controls. • Apple TV: featured demonstrations and the free sampler on the big screen, spin pages with a level control, every solo and partner dance, and CORE AI. One subscription unlocks every device.
FREE SAMPLER Demonstrations from across the library, open to everyone with no subscription needed.
