This app helps you organize and manage household cleaning tasks and activities. Pick a room (i.e. bedroom), select the tasks you want to complete (i.e. make bed, dust, clean closet) and check-off when tasks are completed. One thing I love about this app is that it shows you what percentage of the room is clean -- so you can quickly see which rooms may still need some attention. You can also set personal task reminders such as "Cleaning Supplies" that will remind you what to pick up at the store.
Want the kids to help with your spring cleaning chores? Chore Bank allows you to set up a chore list, assign a monetary value to each chore, know when a chore has been completed and make deposits into your child's account. You can even download a chore calendar and text reminders to your kids!
Android
FlyHelper not only helps you keep your home clean and your life up to date, but you have access to great reminders from the FlyLady herself such as "take a few minutes for yourself" or "check your calendar for tomorrow's events." Track everyday/weekly repeating tasks, control how you clean your home by creating "zones," plan a menu for the week and consult with "FlyLady" to know which "zone" you should work on each day.
Warning -- this app could make you fall in love with spring cleaning. In addition to helping you create checklists for every room of your house, Spring Cleaning Checklist gives you tips for organizing family spring cleaning days, includes video tips and tricks and has music you can listen to while cleaning your home. You will want to use this beyond the spring cleaning season.
