+# SwitchBot Desktop App
+
+There is currently no official desktop app for SwitchBot, so I’ve created one.
+
+This application uses the **mobile API** (instead of the limited Open API available on GitHub), allowing it to support more features and eventually match the functionality of the official mobile app.
