## What is K&S Jump?

Kiss & Score is a practice tool for analyzing figure skating jump videos. Jump analysis is free with no usage limit.

Select a video from your library or record one directly, and the app shows rotation count, air time, estimated height, and landing in a single view. All analysis runs on the user's device. Videos are not transmitted externally by default; a video is sent only when the user attaches one while reporting an analysis error and consents to it. The app does not collect information such as school names or real names.

Key features
· Jump video analysis — unlimited and free
· Analysis history — up to 5 saved on the free tier (delete existing records to save more)
· Recording guide — how to film for better measurement accuracy
· Skeleton (pose) view — review posture as skeletal lines and manually correct detection results
· Measurements are estimates and may differ from official scoring results.

Pro subscription (optional)
· Unlimited saves, and comparison with earlier videos to track change across a season
· Auto-renews and can be cancelled at any time.
· No account is needed for anything — including Pro purchases. Signing in is optional, only to use Pro on your other devices and in the score sheet app.

The app serves no ads, minimizes the data it collects, and is designed so that users can delete all of their data at any time.

The app is now called K&S Jump.
Analysis results now show a dotted trunk line from the center of the shoulders to the center of the hips.

Fixed an issue where the app could freeze or close during analysis.

In compare view you can slow both jumps to 0.25x or 0.5x, and it now starts at 0.5x.
Pinch to zoom on the compare and skeleton screens.
The skeleton lines up with your video more accurately during playback.
The takeoff and landing you mark by hand are kept with each jump.

### 1.0.3 — 2026-09-13

Jumps you record live are saved to Photos and the app, and go straight into analysis (60fps).
If we couldn't give a rotation count, mark the takeoff and the moment the blade first touches the ice, and we'll measure again.
The skeleton is thinner, easier to read, and better aligned with your video.
Rotation speed is now shown as average rotation speed.
If a jump falls short of the one you selected, we show the rotation speed and airtime needed to complete it.
You can report right away when a result looks off.
