Glasswind is a wrist-native focus timer that replaces the Pomodoro ring and digits with a literal animated hourglass. Wind the Digital Crown to pour sand into the top bulb. Tap once to release it. Watch the sand fall through the neck while you do the work. There are no presets, no settings screen, no phases — just one glass shape and one decision: how much time do I want? Why Glasswind: • Physical, intentional starts. The crown is not a value picker. It is a winding action: about one minute per turn, with thirty-second detents. Wind as little or as much as feels right for the next chunk of work. • A visual model you can actually see. No big digits, no countdown ring, no phase color shifts. The remaining time is a small label below the glass — secondary, monospaced, dim. The hourglass itself does the talking. • Background-safe. Lower your wrist, walk to the kitchen, come back. The sand level resumes where it should be, computed against real time, not a paused frame. • Standalone watchOS. There is no companion iPhone app to babysit. Install once on your watch and it works. • Quiet by design. When the sand runs out you get a haptic and a local notification. That is the whole alert surface. • Private. Glasswind never talks to a server. The only thing it stores is a small daily count of completed sessions, synced across your own Apple devices via iCloud key-value storage. No accounts, no analytics, no third-party SDKs, no advertising. Use it for: • A single focus block before a meeting • Stretches of deep work, sized to the moment • A timed break — wind two turns, tap, walk away • Cooking, brewing, anything where you want a glance, not a beep Glasswind is the timer made of glass. Wind the crown. Tap. Work.
