Laundromats, gas stations, restaurants, and other companies in the service-industry would find use in a technology like this.
For context, I designed a laundromat management system for one of the largest manufacturers of laundry machines in the world. Part of the work was flying out to meet with laundromat owners to find out their biggest issues. Scheduling and communication of schedules was a big sticking point (though not something that we ultimately designed into the system we launched).
For recurring tasks and work schedules, do you know which platforms people are using nowadays?
