Afterthat chat is a mobile application designed to extend conversations that begin at in-person events such as meetups, parties, conferences, conventions, hackathons, weddings, and other gatherings. The app allows event hosts and attendees to continue discussions after the event concludes, providing a space for follow up communication that is separate from general social media platforms. It is free to join and free to host, and is available for both iPhone and Android devices. The primary function of afterthat chat is to create a dedicated conversation channel linked to a specific event. Hosts generate an invitation through a link, QR code, or invitation code, which they share with attendees at the event. Once attendees join, they can participate in ongoing discussions that persist after the event ends. The app supports both one-off events, where the conversation naturally fades, and recurring events, where the same conversation thread continues from one gathering to the next. Example usage includes post event check ins, sharing follow up materials, or simply maintaining social connections formed at the event. Key features include the ability to meet in person first, then connect digitally through a shared invitation method. The workflow involves three steps: meeting at the event, receiving the invitation, and continuing the conversation afterward. The app does not require a separate social media account and focuses solely on event based group chats. Afterthat chat is developed and maintained by Secundus LLC, with contact information provided for support. The app is listed on both the Apple App Store and Google Play Store.
