Ok, so I have used numerous calendars for my business, and without a doubt there has been some feature lacking in each one of them...... until now. I just purchased it, and this robust program has everything I need in one place. I am still awaiting for my DNS so I can use my own domain, but everything I tested so far has been amazing. The SMS integration works flawlessly, and I like that I can buy credits as needed. BTW 1 credit does not = 1 text, so read the detail on this. 1 credit goes MUCH further then just one text. I would personally like to see a little bit more fluid set up, but their videos showed where I was missing assigning locations to an employee to then make it visible. (Just watch the videos first, I didnt) With all the features included in my tier, and the fact I didn't have a need for any agency features, I cant recommend the program enough. Sorry appsumo, I even like it more than tidycal. This has some advanced integrations that I need for my particular services.
