This is a simple application for user created flash cards designed to replace physical index cards rather than provide educational content of its own.
The main functionality of the app is quite straightforward. You can cycle back and forth through cards and flip them to see what's written on both sides.
The user creates cards on their own by entering the front and back text manually.
Cards are grouped into lessons, which are further grouped into subjects. As is the case with the cards themselves, the user defines the subjects and lessons at will.
SoundHue is a simple visualizer for your ambient sound. It uses your phone's microphone to listen to your ambient sound and represent it in a few different ways.
A 512-band visualizer takes up the central part of the screen, giving a visualization with a lot of precision, while a simpler 16-band one is located at the bottom, for a more simplified view. The color of the background also changes with the intensity of the sound!
