Ka-Ching is the application that answers the question, “How much money have I made?” If you are getting paid by the hour, you need Ka-Ching! Simply enter the hourly rate and start the timer. Ka-Ching will keep track of how much money you are making so you can concentrate on the matter at hand. This is a great application for any industry that bills by the hour. Never under charge a client again! A must for tattoo artists, massage therapists, and personal trainers.
