I've been browsing through the throng of generated sites and adware trying to find something that's simple and easy to track and manipulate. Honestly something as simple as the rimworld schedule would work (I've been tempted to boot it up but I can't add notations or change category fields).

Found some things that are similar but very crude and usually in a horrible format. I'm also weary of a lot wanting me to sign up for a "free" version or downloading sketchy software. I suppose there are excel versions but that's more manual entry and was looking for something with sliders I can control and expand to cover time slots. Something a couple of people will use and can easily change around to show their preference.

edit: some examples but not exactly what I'm looking for
(looking for just a day, something less excel looking for ease of visual understanding)
(the boxes are great but feel like the horizontal style is easier and being able to slide the boxes or make the sizes different)

Just use multiple calendars?

I use Davx^5 and radicale to sync one (my own) calendar but you could also have multiple and distribute as needed.

It's less of trying to do "days" and more just a 24 hour period of any given day. Syncing isn't necessary as we can all just sit down for a few minutes on a singular device to get a gist of our needs and what our day is like. The calendars I'm used to usually are great for different events for different days but this is just more of a sleep, work, chores, etc in a day and what times they're available. I'll edit in some images in the upload to explain more what I'm looking for.

awesome link! going through to hopefully find what I need, probably going to pick up a few extra ones I see lol

I’ve used Easy!Appointments in the past, best of luck

Well, you can do that too by just marking the time range and repeating the appointment every day(/monday/...).

I think TickTick has that feature!
