* Runs on Android 1.6 and later. (People with 1.5 phones can continue to use version 3.10, available in the Downloads section.)
\n* Portrait and landscape modes are handled.
\n* Displays gravitation and magnetic field, environmental and geographic information, based on information from the sensors in the device.
\n* Runs on QVGA, HVGA and WVGA displays, in landscape and portrait modes. On real hardware, it has been tested on the T-Mobile G1, Google ION \/ HTC Magic, HTC Tattoo, Motorola Droid, and HTC Nexus One, with some testing on the Hero (not the Sprint one), and LG.<\/p>\n
Accuracy is limited to what the sensors can provide. In particular the magnetic field sensor on the G1 phone seems to be pretty erratic, though it sometimes works quite well; on the Droid, it seems to have some pretty serious issues. This will affect both the MAG tab and the compass in the GEO tab.<\/p>\n

How to Use<\/p>\n
Use the buttons on the left to select the mode:<\/p>\n
* GRAV: monitor the local gravitational field and acceleration
\n* MAG: monitor the local magnetic field
\n* ACO: acoustic analysis; waveform, frequency and sound level analysis of the ambient sound
\n* GEO: display geographical information (enable GPS for full info)
\n* EMS: scan the electromagnetic spectrum for radio signals — currently displays cellular and WiFi signals (you have to enable the WiFi to get the latter)
\n* SOL: display current solar activity data — downloads current solar data in the background (may take a while) and displays it along with current images<\/p>\n
The gravitational and magnetic field displays show the corresponding field information as a 3-D plot with X and Y on a cross-axis plot, with the Z value shown beside it. The elevation of the field above or below the X-Y plane is shown on a separate indicator. The absolute magnitude of the field value is plotted below, and the numeric data is shown below that.<\/p>\n
