Essential apps can you not live without?

[Martin-O2]

hey guys, 

A while back I started discussion on what apps people are currently using. It was interesting to see the wide variety of apps that the community find useful and the thread certainly brought a few apps to my attention that I would not have otherwise taken a look at. 

This got me thinking about which apps I use every day and which ones are essential to me getting through the day. If you had to chose 3 apps that would be the only apps you can use which ones would you pick and why? 

My choices would be...

Whatsapp - I use this to stay in touch with friends and family both at home and abroad. 

National Rail Journey planner - This is a must for getting to work on time as the frequent delays and cancellations mean re-planning my route at least a couple of time a month. 

YouTube - I use this app a lot for tutorials, music and general fun viewing and it would be difficult not to have access to this on a phone or tablet. 

So what about you? If you had to pick only 3 apps that you can use what would they be and why?

Also is there an app that you now use that replaced an app that did a similar job? If so what prompted you to change?

I use one drive too but whichever you use its vital you use some app to back everything up.

The app I use most is Line, all my Thai friends use it so I would be lost without it.
