Earnings Season Tracker

Are there any good applications or sites that do a good job of tracking earnings?

I've been thinking about building something that tracks every earnings announcement made, giving an aggregated view (e.g. beat vs missed; YOY eps growth) by index (S&P 500, Russell 3000, etc.), sector, and industry. And also providing a list of upcoming earnings with these filters.

Would people find that helpful?

I asked Gemini and it failed--miserably:

"Give a complete list in a spreadsheet that outlines every company (including ones beyond the S&P) that beat or missed their latest earnings."

"I encountered an error doing what you asked. Could you try again?"
