Yeah I just have Google keep and calendar pinned to every browser on ever computer / laptop I use (personal laptop, work laptop, computer in my classroom (teacher), office computer).
I'm also ATM having fun with obsidian. I want to open it whenever I go on laptop because it's currently a novelty and I want to look at it. I've got periodic notes plug in, some kind of to do list plug in and another to do list plug in to make them roll over to the next day. I open up a daily note, check my to do and then check Google keep (where I dump thoughts) to see whether I need to add anything else to my to do.
I still need to set up s way to sync to phone as at the moment I can only use on laptop. I've read his to do it I just...can't be bothered.
