Mass Group Text Scheduler

Future scheduling and personalization of mass group SMS Texting​ for Android.

Mass Group Text Scheduler is an app used to schedule group/mass SMS text messages, or reminders, and manage alerts. It's a free app supported by advertising via MoPub.

Version 1.1 added a first name personalization option via a keyword/template, e.g.,: Dear [firstname]. This parses the first name from the phone Contacts and inserts it into the message.

Version 1.2 integrates the sent messages via the app with Android's built in Messaging app, so you can see all messages sent by the app without having to open it.

Version 1.6 has a $.99 in-app purchase option for users to import names into a group via a CSV file. You can also now choose to copy the messages to Android's built in Messaging app. The .CSV file should be encoded in UTF-8 format for best compatibility with non-US characters like accents, e.g., á, é, í, ó, ú, ü, ñ.

Version 1.7 Feature changes/updates:
-Added retry option and detection for signal for SMS or if SIM card is installed. Message will fail if no signal detected and allow you to retry sending.
