Marketplace How to Build Your Own House Cleaning Service App That Users Will Love

12,896 hours is the average time each person spends tidying their homes during their lifetime. That’s 1,5 years or 77 weeks. These numbers hardly coincide with modern reality.

Business people, working moms, single-parent households, elderly people, and anyone else who can afford it, often delegate home cleaning to professionals and use the extra time for stuff they want to do.

With the growing trend of ordering services on demand, no wonder software for the house-cleaning business has already disrupted the gig economy. Due to the increase in self-employment and freelance work, the demand for digital platforms for maids will keep on growing in the years ahead.
