Web App
You can switch between Light, Dark, and System appearance in Siro. Click your avatar in the bottom-left corner of the web app, then select Personal settings.
On the settings page, find the Appearance section and select your preferred option:
Light — always use the light theme
Dark — always use the dark theme
System — match your device's system setting
Mobile App
There is not currently a standalone setting to change between light and dark mode on the Siro mobile app — it automatically follows your device's light/dark appearance setting.
Language (Web App)
The Siro web app can be viewed in English, German (Deutsch), Spanish, French, Portuguese, and Chinese. To change it, open Settings from your avatar menu (bottom-left), then select your preferred language under Language.
Language (Mobile App)
The Siro mobile app interface is available in English only. It does not change with your phone's language setting, and the language you choose for the web app does not apply to the mobile app.
This is separate from what Siro can transcribe: Siro transcribes conversations in 40+ languages on both web and mobile, whatever language the app's interface is in.
