Change the language, theme and text size
Pick Prior's language, switch between light and dark, and set the text size and density. These choices follow your account on every device.
Prior's look is set in Settings → General. Your choices are saved with your account, so a new device you sign in on looks the same as the others.

Language
Prior speaks five languages: English, Français, Español, Deutsch and Português. It starts in your device's language, or in English if yours is not one of them.
- Open Settings → General.
- Under Language & region, open Language and pick one.
The change is immediate. It changes the interface, never your content: task titles, notes, project names and flashcards stay in the language you wrote them in.
Theme
Under Appearance, Theme has three choices:
- System follows your device and switches between light and dark by itself.
- Light
- Dark
On desktop, the account menu at the bottom of the sidebar has the same three choices.
Text size
Text size is Small, Default or Large. It scales the text and the controls of the whole app, on every device of your account.
Density
Interface density is Comfortable or Compact. Compact fits more rows on the screen. On a phone, the touch targets stay large either way.
Good to know
- Language, theme, text size and density follow your account. The notification settings do not: they belong to each device. See Set up notifications.
- The emails Prior sends you (confirmation, password reset, billing) are written in the language the app was in when you signed up, signed in or asked for the email.
- The animations of Game mode have their own switch, Effects, in Settings → Game. See Choose Calm or Game.
