There are many apps and other devices to help runners train, prepare and manage their running style and techniques. However, to my knowledge, there are no apps to help you, your family, and others with the age old task of sorting, cleaning and organizing your home to prepare it for sale.
The only app I know of are strong back and arms, willing helpers, and plenty of trash bags and containers. This will get us through the process. Not even a magic wand will help. Just good old muscle power and time will do the job.
Stop waiting for the app to start working because you will never reach your goal if you keep waiting for that magical app!
