Maintenance is a free Android app for keeping recurring home-care jobs visible without turning a general calendar into a second maintenance system. Add tasks such as HVAC filters, gutters, smoke alarms, appliance cleaning, or water-heater flushing; set the interval; and mark each job complete. The next due date is calculated from the day the work was actually finished, so completing a job late does not make the following interval artificially shorter. A due and overdue board plus completion history make it clear what needs attention and when it was last done. Personal tracking works without an account. Optional shared spaces let households coordinate the same maintenance history. Maintenance has no ads and is available on Google Play.
