 OpenTracks – ein GPS-Tracker, der deine Daten für sich behält.
-Erfasst deine Kilometer, ohne dass es jemand anderes tut.

-Funktionen & Features:
-* zeichnet Sport und andere Outdooraktivitäten auf
-* unterstützt das Markieren interessanter Orte, inkl. Foto-Funktion
-* zeichnet deine Herzfrequenz auf (Bluetooth LE)
-* nutze beim Radfahren deine Trittfrequenz- und Geschwindigkeitssensoren sowie Leistungsmesser (Bluetooth LE)
-* exportiert deine Daten als KML oder GPX
-* funktioniert ganz ohne Internet
+Sport und Aktivitäten im Freien machen Spaß und bieten Training und mehr Selbstvertrauen.
+
+Achte auf deine Gesundheit, indem du dein Training im Blick behältst.
+Die App zeichnet während dem Laufen oder Spazieren mit und kann auch als Fahrradcomputer genutzt werden.
+Interessante Orte können am Weg entlang markiert und mit Fotos versehen werden.
+Messdaten können zur Analyse detailreich gespeichert werden.
+Du entscheidest, welche Daten du mit anderen Menschen teilst.
+
+* Gesprochene Ansagen
+* Unterstützt Bluetooth LE Sensoren: Herzschlagfrequenz, sowie Geschwindigkeit, Distanz, Kadenz und Leistungsmessung beim Fahrradfahren.
+* Höhenmessung mit einem eingebauten Barometer.
+* Anzeige der Höhenmessung in EGM2008 (über dem durchschnittlichen Meeresspiegel); Export als WGS84.
+* Export deiner Streckendaten als KMZ (inkl. Fotos), KML oder GPX.
+* Kein Internet oder zusätzliche Berechtigungen nötig.
+* Dunkler und heller Modus, sowie automatische Anpassung an das System.
+* Keine Werbung.
+
+Freie Software / Open Source
