Here’s an example On calendar: you have a meeting 11am-12pm. Tasks You need to schedule an appointment by 11am. This will take 30 mins. You need to do grocery shopping by 12pm. This will take 1 hour You need to eat lunch by 1pm. This will take an hour. You have an assignment due at 6pm today. This will take 3 hours. (Note that this is only in the context of 1 day, but this could easily be in the context of a week with many many tasks and many many deadlines.)
Is there a todo list app that uses time estimates to automatically calculate whether or not you'll overshoot on these deadlines so you can accurately tell people if you do / don't have time to schedule a meeting with them or have an easier way to say yes or no to random events that pop up throughout the day?
I created a very jank one with google spreadsheets, google calendar, and google scripts, but would prefer something that is more "smooth" (lower barrier to entering tasks and calculating overshoots) than having to re-run a Google script every single time.
