❓ FAQ

What is GRUP?

GRUP is an event scheduling app that allows you to create recurring events, invite friends, and keep track of their RSVPs.

How is it different from other calendar apps?

One of the core tenets of GRUP is simplicity. As there are many calendar apps out there, we wanted to create a tool that is easy to use and focused on group events.

GRUP (as the name suggests) is all about groups. First, you create a group (or join one), then you can create events that are shared with the group members.

It also has a particular focus on recurring events, so that you can set them up once and forget.

How do I invite friends?

Once you create a group, you have 3 options to invite friends:

1. Share a single-use invite code;
2. Add a friend by email;
3. Add a friend by phone number.

Do I need an account to use GRUP?

Yes, you need an account to use GRUP. We are investigating ways to allow anonymous users to join groups in discussion #148 - feel free to join the conversation!

What if my friends don't have the app?

If your friends don't want to install the app, they can still access the event on the web.

If they don't want to interact at all, admins can still track their RSVPs in the app.

We are discussing how to allow users to reply to single events without having to sign up here: #148

I have a recurring event, and users have a default RSVP. How does that work?

When you create a recurring event, each user can set a default RSVP for that event.

For example, if you have a daily event (including weekends), and you always attend during the week, you can set your "default reply" to "weekdays" and be marked as attending for all weekdays.

I need a recurring event that doesn't follow a simple pattern. Can I do that?

Not yet, but we are working on it! Check out #154 for more information.

Are you VC backed?

No! We're just a team of passionate engineers who like to make good products, and solve real problems. As we try to figure out some way to bring food on the table, we may have to introduce some paid subscriptions, but:

1. We won't make the core, free tier deliberately worse.
2. We won't sell your data.

As you can see, this is open source software, and if you feel like we aren't doing a good job, you may fork and/or self-host.

I have a feature request. How can I submit it?
