Poslog

Poslog is a GPS logger designed to record the position, velocity, bearing, and altitude of the phone while using far less power than most other GPS apps.

Features:

* Map view shows trace of recorded data, colorized by speed or altitude. Additional Google map base layer can be downloaded automatically.
* Graph view shows a scrollable, zoomable graph of speed and altitude over time.
* Histogram view shows the distribution of recorded speeds or altitudes for the current session
* Constantly records time, location, speed, altitude, bearing, and signal accuracy to easy to read and transfer CSV files
* Runs with the screen off and in the background. Do other things with your phone while the app runs. Save power while not sacrificing data quality.
* Customizable units for all locales and contexts.
* Low power usage, designed to use as little power as possible without sacrificing data quality.
* No service required. Unlike other GPS apps, no network service is required for operation, so airplane mode can be utilized to extend battery life even further.
