GCF Viewer for Android

Güralp Systems Ltd is pleased to announce the launch of GCF Viewer, an app which allows viewing of both live GCF data streams and saved GCF files on Android devices.  Live data streams can be received over WiFi or mobile data networks while saved data files can be received via MMS or email and viewed with a single click.

GCF Viewer allows you to save a list of Scream! servers and to view live data from one or from many, simultaneously.  Subsets of available streams can be selected, sorted, zoomed and viewed with optional real-time Power Spectral Density (PSD) plots or spectrograms.  Automatic display scaling allows pixel-perfect display on devices from smart-phones to tablets. Status streams can also be viewed for state-of-health monitoring.


GCF Viewer is available from the Play Store (requires Android version 4.0 3.0 or above) or, on request, from

A short GCF file is available for testing purposes. You can download it from /download/sample.gcf.

Update: Version 1.0.9, released on September 12th, 2013, adds support for Android 3.0 Honeycomb, along with Turkish and Korean translations.
