BookSteam

Very easy to use and very straight forward so it's simple to get done and show others how to use it.
Being able to cap a group is perfect as well as being able to schedule different tasks (i.e. meetings, appointments, different classes, etc.).
It's key to be able to see an individual schedule or the entire team at once to make planning and changes easier without overbooking an employee.
The client activity history has been great to be able to track client attendance, lateness, NCNS, etc.

There isn't an iPhone app available for Booksteam yet and we keep hoping there will be to make it easier on our team members who use iPhone.
Our biggest con at this time is the recurring client option for classes; you can set clients to recur, but you can't edit the recurring clients. So if a client moves their time permanently OR if a new client needs to be added to that recurring spot, you have to delete the class entirely and re-add it with the updated recurring clients.

One of the standout features of this software is its ability to send reminders and notifications to my clients, reducing no-shows and keeping my schedule streamlined. Additionally, the software's integration with my google calendar ensures that I never double-book or overlook any appointments.

Having more payment gateway integrations would be nice.
