Hourglass: Real Sand Timer

A timer that behaves like a real hourglass. Hold your phone upright and the sand starts to fall. Flip it and the sand runs the other way. Lay it flat and time stops. Every grain follows your phone's real gravity. • Real-time 3D glass, wood and brass under studio lighting • Sand that piles into a cone, drains like a funnel, and only slides past its angle of repose • Swipe sideways for a new hourglass design and sand color • Drag up or down to set 1 to 60 minutes • Long-press and drag to look around, double-tap to face front • A soft chime and a vibration when the sand runs out • No buttons, no ads, no sign-up, no data collection Built to stay light: it draws only while sand is moving, so your phone stays cool. 3D models (CC BY 4.0): "Hour Glass" by Kodie Russell (skfb.ly/6X98q) "Hourglass" by • Less • (skfb.ly/6W9Rz) "Hourglass / Sand Clock" by arloopa (skfb.ly/oSZAS) Licensed under creativecommons.org/licenses/by/4.0.
