Interested in feedback on a new social project

Question

Social media

Hey Habr!

It so happened that we are participating in Yandex Tolstoy Summer Camp . We have an idea for a startup: a social service that selects interesting events for groups of friends, taking into account the interests of everyone and the availability of free time. Events can be different - both ready-made (cinema, exhibitions, concerts, etc.), and created by users (fishing, hiking, sports).
The service solves 3 problems at once:
1) Synchronization of friends' free time.
2) Selection of events for groups of friends, taking into account the interests of everyone.
3) Information about what your friends are doing.
For example, in the evening you have free time. As soon as you are about to leave work, the application sends a notification that today such and such an exhibition is taking place in such and such an exhibition hall, which will be of interest to 3 more friends.
How does the service know about the availability of free time? It is pulled from existing time management systems (Google calendar, Apple calendar, etc.) or you check free time in the application itself.

We are not satisfied with the idea in the form in which it is now, i.e. it is a state of balance between all three problems. I would like to focus on one of them. Please answer 2 questions:
1) Would you use such a service?
2) What is the most interesting thing about this service for you?

1. Know the plans of friends
2. Selection of events based on your graph of interests
3. Let your friends know when you are free

Thank you very much for your help!

PS We will be glad to constructive criticism, as well as any suggestions and ideas

Answer 1

I would even use it, and I am interested not only in these three aspects, but even some that are not described. These three are the bare minimum.

Answer 2

Sometimes I would use it if there is the following functionality:
1) For example, I wanted to go to the cinema on Wednesday evening. I go to the site, choose people for the trip, press "arrange a meeting" (for example). They receive a notification and either agree or refuse, the decision of each of them I, like any other participant in the meeting, can review. A chat is organized for those who agree and they discuss further actions. If possible, keep correspondence until at least +1 day from the meeting.
2) If, according to the first principle, I didn’t find anyone, then we go out to the global search among the rest of the users, which is also free on Wednesday evening and see what they want to visit. You can make a separate item "Age category" (20-25 for example), displayed as desired. Choose a suitable meeting and join it.
And no one fills the calendars completely. I don’t know a single such nausea, so that I sit and paint all my upcoming actions on the calendar.

Answer 3

1. Yes.
2. A function that would send my friends a request like: “In 30 minutes to Charlie, yes / no”, and we all saw how many agreed and refused and who they were.

Answer 4

It would be great if all people interested in a certain topic could answer yes / no
to a certain initiative. In order to understand from the list of friends on vk\fb - who is suitable for an invitation
- a person (the organizer of the meeting) has to remember. It would be nice to give a classification
by groups, some kind of system . Another person should not care - where
to get traffic from (fb/vk/odnoklassniki/linkedin/email/skype/icq/irc).
I clicked the button
- everyone who is interested in the topic is invited.
