I have recently had a big change in the planner area. I've been using my Adelphi slimlines (with the odd change to a compact for a while here and there) and everything has been well with the world. But I got sick of writing all my 'to-dos' out over and over again and with not all that many scheduling appointments, I just found that something had to change. So I now use an EXCELLENT task manager app on my smartphone in conjunction with a mini Filofax. The app I use is called 'Tasks: Astrid To-Do List' and it's realllllly good. I split my tasks up into categories (remember, shopping, to do etc) and have a widget for a couple of the important categories on a page of my smartphone homescreen. The tasks repeat and having a school-age daughter means I have lots of repetitive tasks so it works a treat. My 'today' list is on a full screen on my phone and I just tap the box when I've completed the task, then it regenerates it for the next day/week/month etc. Easy peasy. You can also set the task manager to remind you at specific times of a task that needs completing. I find this really useful because if I'm honest, I often forget to look at my Filofax for tasks!!!
Then comes the Filofax. I use my mini raspberry Chameleon just for scheduling my life: appointments, meetings, work days, on call days, activities, school holidays etc. I don't like the idea of having to fiddle about with my phone when I'm on a call and need to look at my diary. I will never move away from a paper-based diary system for this reason; smartphone diaries just don't work for me. I've tried. And I like that the mini Filofax is so small it doesn't take up too much room in my bag.
Do any of you use technology in conjunction with a smartphone???
