SportWetter

When does the weather suit outdoor sport? Heat, cold, wind, rain, air.
New in version 0.5.0
A new look matching the website: one typeface (Manrope), calm surfaces, the verdict as a coloured card with temperature, heat and wind.

The overview is reorganised: start and duration of your session right below the verdict, followed at once by its assessment or the best time. Plus the hourly course per day with your session marked, and an outlook on which day fits.

The diary is tidied up, cards and sliders are consistent.
SportWetter shows you when the weather suits outdoor sport: heat stress by WBGT, cold, wind, precipitation, thunderstorms and air quality, for nine sports and the next 72 hours.

Overview
Search for a place or use the approximate location. The app scores the forecast on the device: the verdict for now or for your session, the best time, the hourly course per day and an outlook on which day fits. Official severe weather warnings appear in the wording of the weather services. Where the sport needs it, water temperature, rock condition and the regional avalanche bulletin are added.

Plan
Set a session with start and duration and hand it on as a calendar file. A drinking and eating plan for the hottest hour. A route from a GPX file, a chain of places or a distance is split into legs, and each leg is scored at its arrival time.

Diary
Record sessions and rate the conditions, the heat profile learns from that. Import from GPX, TCX or CSV.

Settings
Heat profile per sport, body profile, training times and alert thresholds. The backup is a file in the same format as on the website sportwetter.eu. The score can be exported hour by hour as CSV or JSON. Display and input work in metric or imperial units.

Your data
No account, no ads, no analytics. Profiles and diary stay on the device. Only coordinates and search terms go to the sportwetter.eu server, plus the version number of the app. Permissions: internet and the approximate location, which is requested only on tap.

SportWetter measures nothing on your body. The recommendations rest on published thresholds and on forecasts that can be wrong. The responsibility stays with you.

German and English, following the language of the device.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.

  • New in version 0.4.0
    Less clutter: settings and the secondary cards under Plan start collapsed and show their state in one line.

    Drinking and eating restructured: hourly amounts on top, the schedule as expandable sections, with the session itself open.

    The overview names the hour it rates (Now · 14:00–15:00) and, shortly before the full hour, the next one if the verdict changes there.

  • New in version 0.2.0
    New: score export as CSV or JSON for recalculating. Imperial units for display and input.

    Fixed: after switching the language while the app was running, verdict and reasons stayed in the old language. The place search shows the elevation so places with the same name can be told apart. With an "ideal" rating the app no longer advises lowering the intensity.
