Link does not work at all, technical support is more like in the dark ages, when they try to convince you that you are incapable and stupid. As a solution architect i was trying to test it for a client, but I gave up now. Reading some more reviews - I realised that I should have never get anywhere near it.

I was about to purchase this, but I've realized that reminders require me to manually enter the phone numbers of clients... I would have happily paid the cost if the numbers were automatically added either by the client or through googles data base. I've also realized that 50 SMS reminders isn't 50 different events, its 50 texts... for almost 300 dollars a year, not worth it.

I like the concept, but I literally couldn't use it. I went with the Free version (if you scroll to the left, there are other options, with different prices) to test it, but when I went to try an SMS text test, it kept telling me there's "invalid data" - the only thing being that the Reminder Status was "not set" - but there's no way to change it that I can see. I go to "Manage Account", thinking maybe I can change it there if not in-app, but no. It just goes to if I want to change to a paid version. It's a broken app, and I'll unfortunately have to delete it.

Well, I should have read the reviews. Free but they want my credit card info before the app can be activated. No thanks. I'll remove the app.

As an individual user, $19 per month for the simple task of automating an SMS is crazy high. Better luck getting enterprises suckered into this scheme. I'm deleting now.

Can't really say I "hated it" bc I couldn't use it. It installs fine, I think. But there's no trial period and $20/mo. is pretty steep, and possibly non-refundable. What am I gonna do? Sue them if they don't refund me? Had there been at least a 2-3 day trial period I may have been onboard, although $20/mo. for a calendar widget is pretty high rent, IMO. Which is what makes me even more suspicious. Sorry!

I have no problem paying for apps that I use and that create value for me. But the cost needs to be proportionate to the value -- and this app doesn't even come close. At more than $200 a year, this add-on would cost more per month than my Google Drive and Office 365 subs. I can't begin to justify that for a service that I would use only for myself 95% of the time -- and even then, rarely more often than a few times a week. It's bothersome because it's inexplicable: The developers are, without a doubt, leaving a lot of money on the table with an inflexible and unrealistic pricing model. I could see this getting a lot of traction with a couple of lower-price tiers, especially one that allows SMS messages only for the subscriber's personal use, rather than for invitees. I guarantee you 99 percent of those users aren't paying $19 right now. And if the devs think a low-price option would cannibalize their existing customer base, they might want to book a return trip to Planet Earth and rethink their assumptions. (For that matter, why not add an enterprise tier with custom pricing, volume discounts, and perhaps additional management/access tools? Big customers are no more likely to accept this ridiculous pricing than smaller ones.) I don't know what the developers are thinking, but right now they're screwing up their business model so badly that it's downright embarrassing. Here's my invitation: Hire me to sort out your product offerings and pricing, give me a modest share of the revenue I unlock for you, and let's all make some money :-) Or, you know, keep this up and don't make money. That's easy enough to do.
