Best Hive Tools?

Looking for the best Hive tools that make your life easy easier managing your Hive account. Can be tools on Hive chain or ones that you use on your computer/phone.

Best phone app? With how busy my life has been it's probably time for me to go purely mobile so would love to see any mobile apps for posting, photo resizing, and so forth that everyone uses.

Just an example of one that I like is FastStone Photo Resizer. It allows me to take my high resolution photos and shrink them down. This tool is great for more then just Hive.

So please let us know the tools you use the most! Please help make the comments a powerful resource.
