Wifi File Explorer

This app lets you browse files on your phone without plugging it in or removing the SD card. It works through wifi, letting you connect directly to your phone through your router. It’s as easy as opening the app, opening the web browser on your computer, and typing in the local IP address of your phone. There is an option to set a password, and your phone is only accessible when the app is open, so the security is good as well.

Amazon Appstore

It’s an app store from Amazon. There is an app of the day, which is always an app that costs money, but on that day, it’s free. So you get free apps that you would otherwise have to pay for. Not much more to say.

Advanced Ruler

Just as the name of the app suggests, this is a ruler for your phone. Ever need to measure something but didn’t have a ruler around? This app makes measuring small items as simple as putting them next to your phone’s screen. The ruler can be adjusted for any resolution so it should work with all phones.

ConvertPad

While not very polished in terms of visuals, this app is the best free converter I have seen. There are options for almost anything that you can possibly convert, and it lists multiple results at once so you don’t need to switch back and forth between units.

Andie Graph

This amazing app lets you have a graphing calculator right on your phone. It is an emulator, so you must get your own ROM, but that isn’t a problem. Now if I forget my actual TI calculator at home, I don’t have to worry because it is right on my phone. It’s really a perfect emulator and you’ll feel as if your phone is a real TI calculator.

TeslaLED

This little app lets you do many things with your phone’s built-in camera flash. There is the option of using it as a normal flashlight, as a strobe light, as a morse code beacon, as a timed light that turns off after a set amount of time, and as a hold-to-light flashlight. Plus it can use your screen to display hazard lights and police lights, which is just a cool bonus. It also comes with a widget so you can activate your LED without even opening the app. Very convenient.

SiMi Folder

This is the best folder organizer I have found. You can create many different types of folder widgets and customize them in many ways. It’s the best way to organize all your apps, rather than having them in one giant list where it’s hard to find anything. Just make some folders for a few different categories of apps and games, and suddenly your phone becomes much more useful because you can actually find the app you’re looking for.

Alarm Clock Xtreme

This is a very cool alarm clock. There are many features, such as having to solve a math problem to turn the alarm off, for those of us who tend to hit snooze while still being completely asleep. You can also customize the vibration and ringing, making it gradual, you can make a large snooze button, and so on. You can even set it so it turns off only when the GPS senses that you are moving. It also comes with a cool clock widget.

Embiggen

This simple and very polished app lets you enlarge text on your screen. You type a message, and it displays the words as big as possible. This can have many uses, such as communicating with people in cars without having to open your window, talking to someone next to you when you can’t actually speak, such as at a lecture or at school, and I’m sure people will find even better uses for this app. It might not seem useful, but it has potential to create funny situations, and might even come in useful sometimes for something important.

Parcels

If you buy a lot of stuff online, which you should because 99% of the time it’s way cheaper, then this app will keep track of all your shipments. You can customize which carriers show on the add list, and you can point your phone at a QR code so you don’t have to actually type in the tracking number. Very good way to stay organized and to know when to expect your packages.
