Quickly plan informal events with your friends and find out who's in and who's out. No need for emails, social media logins, or clunky text messaging when you can quickly create an event, invite friends, and get notified of their attendance, even "plus one's." It's just enough for quick get-togethers and nothing more! Create an event by simply answering who, what, when, and where, and receive notifications as invitees respond in or out. Organize friends into invitee groups for quicker event creation, communicate with invitees using event messages, share photos and videos from the event, even get the weather forecast of upcoming events. Perfect for girl's night, sports roll call, and any other "ad hoc" social event where you just need to know who's attending with as little hassle as possible. Want to send a formal invitation on frilly stationery with an RSVP? Well this app isn't for you! But it's perfect if you just want a quick and easy way to get together. Can't bear the thought of doing anything outside of text messaging? We've got you covered...just use Muster inside Messages to create and respond to events for a conversation.

Muster boasts a impressive array of features to meet your Event planning needs. From creating the event, posting pictures of the event, weather, and maps. What truly sets it apart is the minimum/maximum feature. If you have limited tickets or limited number of golfers needed for a tee-time, you can set those parameters. Reminder are set to ensure no party, game, concert, or tee-time is missed. Highly recommended! ### 5/5 — Get together *2023-02-17* I have 3 different friend groups I use this for.
