Owlet a bullet journal to list tasks
That sounds cool! I tried bullet journalling when I finished Uni but then I realised that for normal life stuff I don't even need a calendar anymore. but using bullet journalling for the business sounds really nice! I was a bit intimidated by the creativity that people put in it...
Can you tell us a bit more about how you structure your bullet journal?
As for me, I use pen and paper, a booklet, the really simple app by apple called notes. I love it because there is no fancy stuff in it, really just writing things down and making lists and it synchronises between my phone and computer. I guess I like it so much because it is just a digital version of pen and paper. I recently discovered an app called Waiting List, and I can add deadlines to it. It has a tiny symbol at the top of my screen and when I click on it a list with deadlines in front of pretty backgrounds folds out. ? http://waitinglist.site/
I have Gmail, but I use their site Inbox which I find quite useful to check of emails and organise emails in folders.
My partner loves using Todoist. I haven't tried it out much yet but he says it is really good for productivity.
I also use Excel for many things - mainly because I haven't found a good management tool yet, I assume. I note down from when to when I work and in the next field what I did during that time. I use one line per day.
