### 1/5 — Hübsch und übersichtlich – mehr leider nicht

*2022-08-22*

Koordinaten in dd eingegeben. Wunsch: dms-Koordinaten. Ergebnis: Bei zig Versuchen nie eine Übereinstimmung auf der Karte gefunden. Differenz "Tagesreisen"...

**Developer response:** Hey danke, aber es ist eine einfache Umrechnungs App! Der Fehler den du beschreibst kann ich nicht nach voll ziehen, am iPhone und Mac funktioniert die Umrechnung und Karte einwandfrei! Bitte schreibe mir eine Email und wir gehen der Sache auf den Grund!
