Do you want to remember appointments or the various deadlines to your customers? SmsPlanner is for you !!! With SmsPlanner you can schedule appointments and deadlines of your customers and then send your personalized SMS, email, WhatsApp, and Telegram to remind individual appointments. To work properly WhatsApp, you must enter the international prefix of cellular numbers in your contacts (eg "+44" for United Kingdom numbers). You can send a SINGLE message for appointment, or a single message with the SUMMARY of the appointments of a given period.

SmsPlanner can send the appointments to calendars on your iPhone and can synchronize with calendars configured on your Google account. Those who use Google calendars must first add them on the iPhone, and then select them within SmsPlanner by choosing them from the list of iOS calendars. SmsPlanner allows you to specify days and hours for each appointment, but if you get your customers in multiple locations, you can also specify the single address (street and city). In addition, you can print the weekly calendar of appointments. This new version replaces and unifies the previous Free and Paid APP, including all features with no limits and no advertising.
