I am building, OnTheDot, an appointment scheduling app with a feature for tracking and updating business owners on client ETA. If you are a new barber shop, salon or nail shop owner, this app will assist with appointment booking, sending confirmation, reminders and tracking ETA. Come to my site and review the details of the upcoming application. Sign up on the site and receive development updates.

I want to know if there's a market for this application. If you were an owner of a barbershop, salon, nail shop, etc., would you purchase this application for a monthly subscription?
