The best thing about Setmore is that it is very simplified, to the point, and easy to use anywhere. I have ran into clients at the grocery store, park, etc. and instead of them having to call my office to set up an appointment, I can tell them right then what is available and schedule them. We first found the free version as we were transitioning from paper and pencil scheduling to electronic, and we have found that it is perfect for our needs. You can completely customize your schedule to include as many services as you would like for different lengths of time, prices, etc. You can also add employees and customize other features including colors for services (as they appear on your schedule), office hours, and scheduling intervals. You can add as much or as little contact information about your clients as you would like. Also, I have had to contact customer service 3 times during our use, and they have been GREAT every single time. They have resolved any issue that I have had within 24 hours and were very open with communication, keeping me informed with progress.
There are a few things that I wish Setmore was a bit better about... Setmore is not really "secure". A medical office, for instance, would probably not be able to use this option for scheduling. The only real "issue" that we've had with using the app (on iOS) is that it does crash upon opening quite frequently. It does open on the 2nd or 3rd try every time, and we have never contacted customer service about this issue because it really hasn't interfered with our productivity.
