About this APK

It asks for 8 permissions, 4 of them sensitive, including precise location, approximate location and read shared storage.

Description

From the listing uploaded by “appupdater”.

The Grid Locator identifies where you currently are in the Lambert Azimuthal Equal Area (LAEA) coordinate system, and makes a sound whenever crossing the boundary from one grid to another. It also provides a compass that points north if your phone has a geomagnetic sensor. Note that the Grid Locator does not navigate you to a target location, it only reports your current Grid ID. Technical details: We use the LAEA to divide the world into grids of size 1km-by-1km, which are further subdivided into 100m by 100m subgrids. We set 20°E, 5°N as the center, which is near the center of Africa. Using your GPS sensor, the app determines your current Grid ID (GID) by taking the LAEA coordinates (x,y) in meters relative to the origin and computing E-value = ⌊abs(x)/1000⌋ and N-value=⌊abs(y)/1000⌋. The GID string is then written as: GID=E43-N51 where 43 and 51 are example E-values and N-values, respectively. If x is negative, we replace "E" with "W", and if y is negative, we replace "N" with "S".

Grid Locator APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Grid Locator APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 2692b2fb7957e0f73bf7f3135fe7c4ea.
