Most Useful Apps For the Phone?

Hey guys rather than just gaming I am wondering if you guys have seen or use any useful apps that helps turns your phone into a multitool.
I know for me the flashlight app, scientific calculator with conversions and even a simple map makes my phone so useful at times. But other than those basic three I don't really know any other useful apps. If you guys have a recommendation it would be greatly appreciated.

Flashlight and GPS are the only tools I use :P

There is a blog with the reviews of the latest apps. It's called appotatos. I follow their newsteller and already found a lot of interesting stuff there. It's not only about entertaining apps. I found a great weather app, apps for streaming, and even for buying/selling old stuff for a good price. Hope it will come in handy.

There are many new games that you can try. The games are Android RPG games and they are as follow. The flashlight and GPS ARE USED. Hp Support Using which people can never have to install the various app for various purposes!

For me very useful apps is everynote, slack an redit , by the way. Everynotes helps you organize you local lanscape and help you make good notes during your work activities. Slack- you can create various channels for various tasks or various groups of people. It’s great for a lot of things because the chat service can be integrated with a ton of other services such as Asana, Giphy, Google Drive, Twitter, Zendesk, and other productivity tools.
Redit- helps me find  advice, tutorials, and information about basically anything. I recommend reading good information here: https://truowl.com/ about education and posibility to make this process with a lot of fun. Not only mobile apps provide good stuff for you, also and good news platform.
