Why I built this: I created this tool to support my own finger strength training for climbing. I needed a timer that was simple, customisable, and worked seamlessly on mobile. Existing apps were either too rigid or too complex. This web app helps me stay focused, track progress, and stick to consistent crimp sessions—with built-in audio, visual, and haptic feedback to guide every rep. Christian Kortenhorst
