Rung
Read full descriptionHide full description
Most kitchen timers were built for boiling eggs. Rung was built for the rest of it. Set steps before you start or add them on the go. Anchor each one to the start or end - reduce heat after 10 minutes, brush with egg yolk 5 before it's done. No ads. No subscriptions. No cluttered menus. Just a dial, your steps, and a timer that feels like it was made to be used in a kitchen. Live Activity on your lock screen keeps your current step visible without unlocking your phone. A real bell tone and vibration that cuts through even on silent. Designed with the same care as the tools already in your kitchen. Good food takes time. Rung keeps track.
