AppToTo: rocks. We didn't think we could afford a reminder service-- but our overall AppToTo experience has shown us that we can't afford not to have it. Our no show rate has plummeted, and our clients now think we are technically savvy....
Not only do our clients get an automated phone call confirming their appointments, but they also get a SMS message on their phone reminding them of the appointment. These guys even send us a text message when clients cancel their appointments.
While the interface on line seems overly simplified, the real genius of this software is the people who run it. They have been great about customizing the service to fit our needs. The overall customer support has been fanatical!!!!
The biggest problem with the service is that they don't make it apparent how customizable it is. Hopefully, they'll revamp the web site to include greater emphasis on how to reach customer service, and make it more obvious that this product is the "swiss army" knife of reminder services.
