What i use on my mobile to organize my busy days

Ii use the two previously mentioned apps but mostly i use the calendar the most, this gives me a synchronization with my works outlook calendar so i can put reminders in both to help remember to be at appointments and also to remind me to do things.

I also use email and if anyone asks me to do something i will ask them to email me to remind me.

i will mark the email as not read if i need to deal with it later.

I have a calculator and a converter which will do length mass etc and i regularly use a London underground app for the tube journeys i take.

these may all seem like general day to day apps but to me they are how i get by on a day to day basis and i would struggle badly without them.
