Crux

Upload your climbing video, and Crux does the rest.

Crux is an on-device analysis app that uses AI pose analysis to read your climbing videos, score your posture, and identify the most difficult crux sections and their causes.

[Analysis Complete with Just One Video]

Simply upload your recorded bouldering video. On-device AI tracks your body movements frame by frame to generate a comprehensive score and a detailed report.

[Crux Report]

It explains where and why you got stuck—presenting pause times, problem types (posture, foot position, arm reliance, etc.), causes, and hints. Tapping the time chip on the timeline jumps the video directly to that point.

[Flow by Move]

It doesn't just list problems. It tells you the entire climb in move order, showing which moves were smooth and where the flow was interrupted.

[Measurement Signals]

Detected techniques like drop knees, flagging, and heel hooks, as well as center of gravity flow and straightness—it displays values ​​measured directly from the video, separate from the score. [Next Try Plan]

It doesn't stop at analysis. We suggest three specific steps that you can immediately apply to your next attempt.

[Records of Growth]

Score trends, weekly activity, and personal bests. As your analysis accumulates, you can see your climber type and your next challenge. You can even compare two videos of the same route side-by-side.

[Privacy First]

There is no registration or account required. The entire pose analysis process is performed on the device, and the videos are stored only on the device. You can use it without an internet connection.

Recommended for:

- Climbers who feel their bouldering skills have stagnated

- Those who want to view their posture objectively

- Those who want to build a database of their climbing records

The analysis results are for reference only, based on automated video analysis, and accuracy may vary depending on the shooting angle and lighting.
