As a small business owner and software developer, I am insanely busy with coding, meetings, clients, and work in general. I've completed my own testing of this app and it does exactly what it says it does. I am so impressed that I will be subscribing to the paid version. What I like? 1. Intuitive user interface 2. Installation and on-boarding is simple 3. Connectivity with Google Calendars is simple to setup 4. The app hasn't dropped the ball ever! If it is in my calendar(s), and I've configured the app to send an SMS based on certain criteria I get an SMS reminder. 5. No more manual texting to clients reminding them of appointments. This app automates the entire flow. A-W-E-S-O-M-E!!! Why I chose this app over other solutions. It solves a problem/pain point" 1. How do I as a small business owner remind clients of our appointments without a) "bugging them with email reminders they may never see," b) how do I choose a solution that our team will adopt and use? c) I don't need to add yet another task to my "apps to code" project list instead... d) use SMS Reminders. Easy. Keep up the great work and to those that are reading this...download this app and check it out!

This is a great add on to google calendar! Never knew I needed this add on as much. But since Im on a Free Cellular Phone Service from TextNow Wireless. They require you to make at least one call or send one text message to keep your free service active. The phone service is free for life. Well as long they stay in business and users are using the free plan. I can just use this to send out a sms reminder weekly! Fo Free! But itll also be useful to me for my work and school and maybe whatever else plans or appointments or meetups I have as well. It was easy to setup and works fine out the gate. Salutes to the developers for this app or software add on. Thanks!

I just tested this app out to see how it works. The reason for this review is because, I was highly satisfied with the app. I give it 5 stars because of the way it was described was exactly the way it worked. It was easy to set-up just follow the prompts. I recommend this app if you have appointments and your job involves you making them appointments. I am a case manager for a rehab. I am responsible for making sure my client's make those appointments on time and as scheduled. I am going to recommend this to my co-workers. Maybe we will start using this app to incorporate our daily schedules.
