Appointment Reminder, not only has a pretty descriptive and unambiguous app name - which is awesome - but allows you (as a business owner that relies on booking clients for appointments - i.e. doctors, dentists, etc.) to easily setup automated appointment reminders for your customers, and gently reminds them via a phone call or text message. Do check it out, you can even try a free demo.
Congrats again Patrick.
I wish you all the best.
