GPX Viewer 0.3.0 for macOS (build 4): Historical Weather

Historical weather for the time and place of a recording in both Mac editions: a Weather inspector with summaries, a timeline linked to the map and graphs, eight modelled graph lines, a local cache and clear attribution.

0.3.0 is the current macOS version. macOS 0.2.0 (build 3, 25 October 2026) and 0.1.0 stay available as archived releases in their own folders. The Windows edition is unchanged (Windows 0.3.0).

New features

• Weather inspector in both Mac editions (the cloud and sun tab; also Track, Retrieve Historical Weather and View, Weather).
• Weather is matched to the recording itself: places sampled along the route about every 10 km and at height changes of 300 m, hourly values matched to each point's timestamp in UTC and blended between neighbouring places.
• Air temperature, feels-like temperature, dew point, relative humidity, precipitation, rain, snowfall, wind speed, wind direction, gusts, sea-level and surface pressure, cloud cover and the weather condition. Visibility is shown as not provided by the source.
• Weather timeline over the recording time (temperature, hourly precipitation, wind arrows), linked to the map marker, the graph cursor and the Point inspector.
• Eight modelled graph lines beside any main measurement: temperature, wind speed, gusts, headwind, precipitation, sea-level pressure, humidity and cloud cover, marked Modelled and credited in the legend.
• Summaries for the whole recording or the selected section: ranges and time-weighted averages, precipitation shared out by the time spent in each hour, prevailing wind, wind along the direction of travel and the most frequent condition.
• A temperature recorded by a sensor in the file is shown beside the modelled air temperature, never replaced.

Improvements

• Answers are cached on the Mac (at most 20 MB): opening the Weather inspector again or working offline shows saved weather without a request; Clear weather cache deletes them.
• Clear messages for missing timestamps, recordings in the future or before 1940, no data yet for recent days, no connection, timeouts and rate limits.
• Installer read-me and welcome screens describe Historical Weather and what it sends.

Compatibility

• Apple silicon edition: macOS 13 and later. Intel edition: built for macOS 10.13 to 12 with the same weather features; its weather code uses only APIs available on macOS 10.13.
• Historical Weather is not available in the Windows edition or in GPX Viewer Web Lite.

Privacy and legal information

• Weather is requested only when you press Retrieve. Open-Meteo receives a few places along the route, rounded to about 1 km, and the dates of the recording; never the GPX file, exact times, names or sensor values.
• Legal notice version 6, privacy and third-party texts describe the weather source, its licence and attribution.

Known limitations

• Weather values are model estimates for grid cells of about 9 to 25 km and whole hours, not measurements at the track.
• The most recent days can be missing or provisional until the archive is updated.
• Uses Open-Meteo's free service for non-commercial use; very heavy use can be rate limited.
• Not signed with an Apple Developer ID and not notarized.
• Tested on macOS 27 (Apple silicon; the Intel edition under Rosetta). Historical Weather has not been tested on macOS 10.13 to 12 hardware.

Installing

Open the package for your Mac (Apple menu, About This Mac: "Apple M..." chip means Apple silicon, "Intel" means Intel). The Installer shows the introduction, the read-me and the licence to accept, and installs GPX Viewer in the Applications folder; it replaces an earlier version and keeps your settings, map keys, imported files and caches. The packages are not signed with an Apple Developer ID and not notarized: Control-click the package and choose Open (macOS 15 and later: try once, then System Settings, Privacy and Security, Open Anyway). Compare the SHA-256 checksum with SHA256SUMS.txt.

Weather data

Weather data by Open-Meteo.com (CC BY 4.0), based on data and products of ECMWF; contains modified Copernicus Climate Change Service information. Neither the European Commission nor ECMWF is responsible for any use of this information. Weather values are model estimates, not measurements, and must not be relied on for safety.

Documents

• Legal notice version 6, privacy and third-party texts: inside the app (Contents/Resources) and in the source archive.
• Documentation and changelog: https://gpxviewerpro.pages.dev/ (private until the public launch).
• Project: https://sourceforge.net/projects/gpx-viewer/ and https://github.com/A097MPRUS/GPX-Viewer (private repository).

Downloads

Public downloads are on SourceForge: https://sourceforge.net/projects/gpx-viewer/files/macOS/0.3.0/ (this repository is private, so the assets below need a GitHub sign-in). GitHub shows spaces in file names as dots; the files are byte for byte those listed in SHA256SUMS.txt.

GPX Viewer 0.2.0 for macOS (build 3)

Archived release. macOS 0.3.0 (Historical Weather) replaces it; these are the original 0.2.0 files published on SourceForge on 25 October 2026, unchanged (same SHA-256 as SourceForge).

Two native Installer packages replace the disk images:

File	Mac	macOS
GPX Viewer 0.2.0 Apple Silicon macOS 13+.pkg	Apple silicon (M1 and later)	13 Ventura and later
GPX Viewer 0.2.0 Intel macOS 10.13-12.pkg	Intel	10.13 High Sierra to 12 Monterey (later Intel systems not tested)

SHA-256 checksums: SHA256SUMS.txt in this folder.

0.2.0 is the current macOS version. The previous release, macOS 0.1.0 (7 October 2026, disk images), stays in macOS/0.1.0 as an archived release and is no longer updated.

New

• Choose the graph's main measurement: elevation, speed, recorded speed, slope, vertical speed, heart rate, cadence, temperature, power, GPS accuracy, barometric altitude, air pressure, device temperature.
• Combined graphs (up to three measurements on their own scales) and stacked graphs (one plot each, shared cursor and zoom).
• Distance, elapsed time or moving time as the horizontal axis.
• Microsoft Azure Maps, TomTom, HERE and Mapbox with your own key, now also in the Intel edition; live map credits for Azure Maps and HERE.
• New app icon (Apple silicon edition).
• Native Installer packages with read-me, licence and architecture checks.

Improvements

• Distinct graph switch icons with explanatory tooltips; VoiceOver reads each switch and tool by name.
• Map credits, Apple's Legal link, compass and zoom buttons no longer overlap; the tool strip scrolls on small windows.
• Intel edition: sharper commercial maps on Retina screens and lighter 256 pixel tiles on non-Retina screens.

Fixes

• Map tiles: no patches of mismatched detail while tiles load (stand-in tiles now always come from the same or a coarser zoom level).
• "Terrain Tiles (elevation data)" is no longer offered as a map.
• Two graph and tool icons that were missing on macOS 13 now show.

Compatibility and known limitations

• Not signed with an Apple Developer ID and not notarized: Control-click the installer and choose Open (macOS 15 and later: System Settings, Privacy and Security, Open Anyway).
• Tested on macOS 27 (Apple silicon; the Intel edition under Rosetta). Earlier macOS versions have not been tested by the author since 7 October (High Sierra on a 2011 MacBook Pro).
• Microsoft Azure Maps has not been tested with a real key.
• An older "GPX Viewer Intel" app installed by drag and drop stays in Applications; delete it after installing.
