Shared family calendar on everyone's iphone, with all medical/dental appointments/birthdays/school events/social events on. I put my work calendar on too, visible only to me, so I know that if I have to make a medical appointment in work time it's not going to be on a day when I have something mega important on in work.
I've discovered the tick list function on my Iphone in Notes last year. Game changer for packing suitcases or making a to-do list of things to sort for going on a complicated trip.
I use the TripIt app for holidays when I'm planning it myself. So useful having an itinerary all set up when you're on a road trip.
We use FindMyIphone in my household (and my mum too) to save time instead of texting/calling to check what time they're on the bus so I know what time to have dinner ready for (DH often has a cuppa ready for me when I walk through the door
, whether they got to school in the snow ok, got to appointment on train strike day ok, what time they are reaching their stop if journey has been delayed cos I'm picking them up , whether Mum got home safely after driving home in bad weather (she lives alone) etc. I can't understand those people who say it's controlling. None of us have anything to hide and none of us want bothering when we're just going about our business, I'd rather let other people see where I am than have to update them as to my whereabouts and timekeeping.
We've had a lot of dental hospital appointments in the family the past 5 years. So many appointment letters! I have a place on the mantelpiece (in front of the mirror by a candle) where I put all upcoming appointments, or stuff to action eg road tax, and once it's been "actioned" I shove it behind the mirror to file away when I've got time.
I have very little spare time in which I am not knackered in a heap on the couch after work. My biggest tip to myself to make my life easier is not to sweat the small stuff and don't have a Mrs Hinch house. I'm not superhuman.
