We have developed and launched an app with a complex search system for sale of services with available capacity. I need an appointment here and now! Who is available? Droppin lets you compare prices and find the salon closest to you. The salon gets to fill up available capacity and you get to do a good deal. We are a service where the salons offer available capacity today and 2 days ahead. The number of available hours varies day by day, along with discounted hours.
