Flexible location: Uses your GPS location automatically, or lets you set any place on Earth manually. Custom time: Simulate the sun's position at any time of day, not just right now. Camera selection: Pinch to zoom to cycle through available back cameras (wide-angle, normal, telephoto).

HexViewer
APK
This application offers the following features : - Opening all files without a corresponding Android application (1). - Display of the file in hexadecimal (or plain text) with the possibility to modify the content (in hexadecimal only). - Saving the file on the smartphone/tablet (2). - Search option in the open file (hexadecimal and plain text modes). (1) At first, the file can only be saved via "save as" and due to Android permissions reasons, the only way to make it appear in the list of recent files is to reopen it. (2) Due to file permissions, after a "save as", the list of recent files cannot be updated with the new file location. Caution: Opening files that are too large seriously degrades application performance and can suddenly stop the application on low-resource devices. **WARNING:** This application cannot open files larger than ~20 MB on recent smartphones and less for older smartphones. **WARNING:** Searching within the plain text view may become excessively slow when handling large files.

APK
Hexpress is a collection of musical instruments for your phone. You can use it for learning, playing and composing music whenever you have the time - on train, while waiting in line and during boring meetings. Using headphones is strongly recommended for louder and better sound quality, and to not disturb others around you. The application has simple, colorful and clean interface designed to be accessible to young children.While each instrument behaves differently in some way, in general notes are played by touching shapes on the screen, and sound is shaped by tilting the phone left-right and up-down. Different instruments have different effect controls - fade in, reverb, wah, tremolo…Most of Hexpress instruments have unusual honeycomb note arrangement that’s sometimes called "harmonic table note layout". It has many interesting properties compared to standard piano layout:effective utilization of device screen (3+ octaves range)note relations (intervals) are uniform across whole range; to transpose song to different key just play same patterns on different part of instrumentmost chord shapes are grouped tightly and they can be executed with single finger swipein typical scale and melody runs, notes are alternated between fingers of two hands, so they can be played with speed and precisionlarge intervals are as accessible as smaller intervalsBesides honeycomb layout there are also instruments with conventional fretboard, and instrument for finger-drumming.
