A note from the maker
Built between
attempts.
I go bouldering, and a lot of my videos start the same way: the same wall, the same holds, another try. I wanted a place to remember what changed.
That's why I made CRUX. Using it at the gym and hearing from other climbers keeps shaping the little things—getting to Record quickly, telling similar clips apart, and leaving a useful cue for next time.
Le QinYour journal, on your phone.
Works offline, without an account. No ads or public feed. Optional copies in Photos follow your Apple Photos and iCloud settings.
A little more room for Beta.
Mark holds and pose a figure on a wall photo. Or use on-device Pose Analysis Beta to inspect one saved frame—not automatic coaching.
A video can be enough.
Add a reflection when you have something to remember. Leave it out when you don't. Available in English and Simplified Chinese.
