Everytime you’re with a group of people and are just getting bored, out of ideas about what you can do together, you can go to this app and find something fun to do. Such a situation occurs often if you hang out with the same set of friends regularly / or are on a trip.

• There could be some pre-existing activity ideas, social games, challenges etc which you can choose from (maybe also filters for number of people, age, time, resources etc)
• People can further submit their own activity ideas / game suggestions.
• Users can upvote, downvote and comment on the ideas. Maybe share any fun experiences they had doing the activity.

This app can easily go viral if people use it since people will want to share the ideas with others before deciding on it, and then post about their experience later.

Marketing for something like this might be on Instagram, TikTok etc along the lines of “stop watching reels, instead, find something fun and social to do with your friends via this app”.

The concept isn’t very well thought out just yet, but if there’s user interest in something like this, coming up with useful features shouldn’t be hard!
