2016-01-10 JW HRM & GPX Tool: New Release 1.07 Available

Change Log:
  • Import, display and export of GPX (file) header date.
  • Improved handling of records without date/time information and new export No-Date Records setting.

2015-12-19 JW HRM & GPX Tool: Release 1.06 Available

JW HRM & GPX Tool was updated to a new release.

Change Log:
  • New “GPS Smoothing”: Smooth/limit GPS values in case of GPS location “hangs” and suddenly jump over to a big distance position. Without smoothing, in some applications such cases result in huge unrealistic Maximum Speed values and charts showing a curve with huge peaks and otherwise only small value differences.
  • Results of GPS adjustments compared to the original values are now shown in a special view within Data View window rather than being just exported.
  • Approximate Total Distance and Average Speed (along with Total Training Time) are calculated for GPX files (based on GPS Latitude/Longitude values) and HRM files (in case of HRM speed values are available) and shown in Import Status and Data View windows.
  • In Import Window there are now two separate file requesters and Run buttons for HRM and GPX import files.
  • TCX export: calculation of Distance Meters information now based on GPS Latitude/Longitude values (since available more often and usually more precise than based on speed values).
  • GPX export: Improved match methods and export of waypoints from HRM or GPX input files, especially in case of GPS adjustments done.
  • Major internal code overwork and clean-up along with several minor improvements.

As usual, the application is downloadable for free within the Download Area of this homepage.

2015-09-05 JW HRM & GPX Tool: New Release 1.05 Available

JW HRM & GPX Tool was updated to a new release.

Change Log:
  • Default Export GPX Time Zone is now UTC accordingly to GPX standard. However, default Import GPX Time Zone stays “Local” as this is the correct setting for Polar files though not following the standard. In case of GPX files are taken from a different source it’s likely the Import GPX Time Zone needs to be switched to “UTC”.

As usual, the application is downloadable for free within the Download Area of this homepage.

  • Bugfix: under certain circumstances some GPX file header metadata contents could get loaded out of the wrong GPX metadata tag.
  • Enhanced GPX file size limit which allows now to import about at least 10 hours of one-second-interval-records along with full trackpoint information. A warning message will appear in case of no GPX end tag could get read and something possibly is incomplete.

As usual, the application is downloadable for free within the Download Area of this homepage.

2014-07-06 JW HRM & GPX Tool: New Release 1.03 Available

  • Export of Speed and Power values to TCX files by usage of Garmin TCX extensions.
  • Added “Adjust to GPX” and “Adjust to HRM” buttons for automatic calculation of the time adjustment value so that the HRM (GPX) start time matches the GPX (HRM) start time.

2011-07-02 JW HRM & GPX Tool: New HRM and GPX Merge and Conversion Tool

Many sports tracking applications and web portals require recorded exercise information to be included within one (in most cases GPX) data file.
However, often heart rate monitor data and GPS data are recorded with different devices or at least separate data files.

JW HRM & GPX Tool merges and converts information from HRM (Polar Heart Rate Monitor format) and GPX (GPS Exchange format) files, and exports data into several file formats.

Download and use it for free within the Download Area of this homepage.

2010-08-18 JW SMS: New SMS Special Type Messaging Tool

JW SMS is a simple and free Java SMS messaging application.
Beyond sending usual and Flash SMS, JW SMS is able to send special SMS types like the " new voice message notification" ones.
By using such special SMS types it is possible to get rid of certain symbols and alerts on the mobile. These might remain e.g. when a mobile network provider (e.g. a different one of another country) sends a new-voice-message SMS in case a new voice message is left, and afterwards the mailbox is called with a different provider, not sending a second no-new-voice-messages SMS.
Download and use it for free within the Download Area of this homepage.
