Startup Idea: Personal Planner and Assistant App with Integrated Calendars

Startup idea to develop an efficient personal assistant/planner application. The envisioned software would offer an integrated view of personal (Google/Gmail) and work (Outlook) calendars along with user-friendly task/event categorization. It would also feature a dedicated space for managing recurring tasks and chores. Unique features may include trend-based recommendations for scheduling, potentially leveraging direct communication capabilities to schedule appointments.

I think there is a seriously lack of GOOD personal assistant / personal planner applications. There are many solutions such as Slack for teams. But many of the PERSONAL planning / task management apps are inflexible. They follow Kanban or Trello style, which is great, but not everyone comes from a tech background where that is common.

A basic tool that would allow users to seamlessly integrate their personal (i.e., Google / Gmail) and work (i.e., Outlook) calendars for a holistic view would be great. Also, if it would be flexible enough to allow for categorization of tasks and events such as Appointment, Business Meeting, etc.

I also think a place to keep track of chores/recurring tasks would be very helpful. If the software could look at trends over time based on this data and make recommendations - for example, we see you haven't booked a hair appointment in 3 weeks but are free Thursday afternoon, would this be a good time? Even the ability to directly call/text/email to others from the app based on recommendations would be worthwhile to explore.
