The thing I liked best about this service was that they offered unlimited call backs for missed appointments from their free office hours! If anything else, nothing really stands out as a problem or issue for me. As mentioned before, being able to have call back's for missed appointments during my free time really helped with our busy clinics schedule. Having scheduled clinic appointment reminders throughout the month really helps keep patients organized and well informed about upcoming medical visits. I love that my schedule is available any time day or night. It's very intuitive which makes for quick set up! The interface could definitely improve but this is nitpicking at its finest! This product has saved me hours each week by having all our schedules in one place. We have never had issues when needing help from customer service because everyone can communicate through their app as well.
