I am adding sync between local calendar and a scheduling assistant.
With calendar sync you can now see all your events in both calendars (your local calendar and SoPlan)
With Scheduling assistant you can automatically plan your next event with friends. Create a new event using conditions "Friday, Saturday, Sunday. Between 1 PM and 5 PM, duration of 2 hours". It will automatically check availability of all participants and creates a new event. No worries about privacy, we got that covered. Magic is done on our servers, you will never see each other's agenda.
What other features do you think can make this app better? Please let me know!
