Why GrindClock?
Most OSRS calculators hand you a number and wave goodbye. GrindClock turns that number into something you can feel: a countdown of grinding nights, a date on the calendar, a goal card built for your clan chat, and a dashboard that remembers every grind you committed to. Set a goal, come back tomorrow, watch the bar move.
Rates are realistic community averages, not tick-perfect world records - the ETA you see is one you can actually hit. Everything runs in your browser and your goals never leave your device.
