Water Bank is an app that monitors abundance and strategizes scarcity. It adapts to local resources for smart water management by offering two modes: When supply is ample, it enters Calculator Mode and tracks daily water use; whereas during shortages, Planner Mode takes over with a low-fi, water-saving interface to help allocate water usage wisely. Functioning like a budgeting app, Water Bank empowers users to manage their water footprint responsibly and sustainably.
