If you mean calendar apps for everyday personal + work scheduling, these are my top picks:

Google Calendar — Best overall. Free, simple, excellent sharing/invitations, and works especially well if you use Gmail and Google Meet.
Fantastical — Best premium option. Beautiful interface, natural-language event creation, strong scheduling features, and particularly good on Apple devices.
Notion Calendar — Best for productivity. Great if you already use Notion; it can combine multiple calendars and connect meetings with Notion pages and workflows. Notion Notion
Microsoft Outlook — Best for work. Calendar, email, contacts, meetings, and Microsoft 365 integration are all together. Microsoft Support Microsoft
Apple Calendar — Best for Apple simplicity. Excellent if you're primarily on iPhone, iPad, and Mac and don't need advanced scheduling features.
BusyCal — Best for power users. Lots of customization and detailed scheduling controls.

My quick ranking

App	Best for	Price
Google Calendar	Most people	Free
Fantastical	Best experience	Free + premium
Notion Calendar	Productivity/Notion users	Free
Outlook	Work/Microsoft 365	Free + Microsoft 365
Apple Calendar	Apple users	Free
BusyCal	Power users	Paid

If I had to pick just one: Google Calendar for most people; Fantastical if you're willing to pay for a more polished experience; Notion Calendar if your life revolves around Notion.

If you tell me iPhone or Android and whether it's mainly personal, work, family, or time-blocking, I can narrow it down to the best 2–3.
