Has everything I need in an app for my massage business. The only problem I have is when booking clients, you can only set the appointment time for on the hour or half past the hour. For example: 10:00am/pm but I can't set it for 10:15 am/pm or 10:45. I can only put the appointment in for 10:00 or 10:30. The other problem that I had was making the duration of my services. I like to have a 15 min. Time gap between appointments and they only have set time: 30, 60, 90 mins. You can't edit the duration time.
