I did for rudimentary tasks and defaulted to 45mins focus / 15mins break time blocks. Recently jumped on the Flowmodoro train which has been helpful doing creative work (https://focusedwork.app has been great for this), since I can keep going until I really need a break and my breaks are a fraction of the time I spend focusing. But yeah Pomodoro is hard to use for anything that I need to focus on for a long period... - Source: Hacker News / 3 months ago

I would suggest Focused Work if you're on a Mac - this is what I use and it will do everything you just described. https://focusedwork.app/. Source: over 1 year ago

Itsycal and MeetingBar - I wish they would cross-implement features! Source: about 1 year ago

Haven’t seen them mentioned yet but ColorSlurp is a slick colour picker and MeetingBar is an awesome meeting reminder tool that lives in your menu bar and gives you a quick prompt to join a Zoom/Teams/whatever meeting. Source: almost 2 years ago

Not what you asking but maybe something like MeetingBar can help you out https://meetingbar.onrender.com/ (I’m not related in any way to that app, just a happy user). Source: about 2 years ago

MeetingBar might be what you are looking for. Source: about 2 years ago
