Custom Group Text is a productivity app designed for iPhone users to streamline group messaging. It allows users to create custom groups, eliminating the need to select contacts individually for group texts. With features like personalized messaging, delivery confirmations, and the ability to schedule messages, it enhances communication efficiency. The app supports both Group iMessage and SMS, adapting to the user's preferences and needs.

Key functionalities include importing contact groups, managing group members, and reusing saved messages via the ReadyText list. Users can also attach pictures and locations to their messages. While this app significantly boosts productivity for group messaging, it is advisable to be aware of carrier limits on SMS recipients and to adjust settings in the Messages section for optimal performance.
