What apps do I use more in my smartphone?

Hi again!
I wanted to do a "trending topic" that many people is doing and is: WHAT APPS DO I  USE MORE IN MY SMARTPHONE?
First of all I have to say that my phone is an LG G2 and I am very happy with it, for me is perfect.
Let's start!
-Pixel Battery Saver:
A very useful app to save battery that, basically, turns off a cuantity of pixels of your screen, it is very useful for moments where you need to use your phone but without wasting so much battery.
-My Data Manager:
I think it is the best app to control your data plan, it shows data, wifi and roaming and estimates how many MB are you going to use. You can also program alarms.
-Strava & Runtastic Mountain Bike:
Very good apps for those that ride their bikes to make routes and control haw many kilometers have you made, I use them every time I go with my bike.
-Aliexpress:
I am a fan of shopping in China, although it takes a month to arrive, the objects are very cheap and I think that Aliexpress is the cheapest market.
-Splive Player:
The best for watching TV on your phone or tablet, it includes public and private TV!! Totally recommended!
I have to say that it is not on the Play Store so you will need to download it from internet.

Those are the most usefull apps that I have appart from WhatsApp, Facebook and soon...
I think it is OK for today, so have a nice day!!
