I think TimeTree is a shared calendar application, could help me share schedules with family, friends. Enough concise.

Answer

For me, Google Calendar has been the standout. The integration across Google’s ecosystem makes it incredibly convenient, especially if you're already using Gmail, Drive, and other Google tools. I also love the “Find a Time” feature, which has made scheduling with my team so much easier, and the option to create different calendar views is really handy for managing personal vs. work commitments.

In terms of taking it to the next level with AI, I’d love to see even more predictive features. Imagine if the app could intelligently suggest meeting times based on past availability patterns, analyze the optimal time for tasks to maximize productivity, or even recognize recurring events and suggest optimizations. AI could also be really useful in handling schedule conflicts by proactively offering solutions.

Calendly :)

Answer

My favourite one is Google Calendar because of its seamless integration across Google Workspace, smart event suggestions, and user-friendly design.
I love the color-coded calendars to separate work and personal tasks.
As for AI potential, I do believe that AI could enhance Google Calendar by analyzing task priorities and patterns to suggest optimal time blocks for deep work and low-stress productivity. Another cool addition? A proactive “reschedule assistant” that could automatically reorganize meetings based on current workloads or deadlines would be perfect!
