Harmonizely

We at Absolute Reg are using Harmonizely for 1-2 years now. It is by far the most intuitive, detailed, and efficient scheduling software that we have used. You just have to set your calendar, share your scheduling page link to people then let them choose to book the best date for a meeting. One of the significant features of Harmonizely is that it is compatible with almost all calendar systems. It monitors and consolidates all of your calendars in one platform to identify your availability. It is so efficient that it saves you from checking your emails and calendars from time to time in finding your available schedule.

Pros: Harmonizely is less expensive compared to other scheduling software in the market. It is cheaper without compromising its quality service, robust features, and functionalities. 

Cons: It doesn't have an app yet. You have to book and do everything from their site, which can be inconvenient sometimes. Booking an appointment should be faster and more hassle-free if done through an app.
