Changing the App Theme (Dark Mode)

Helium supports Light, Dark, and System-synced themes. You can change the theme at any time from Settings.

How to Change the Theme

  1. Open Settings
  2. At the top of the Settings screen, find the three-icon theme toggle
  3. Click your preferred option:
    • Light (sun icon) — always uses the light theme
    • Dark (moon icon) — always uses the dark theme
    • System (auto-brightness icon) — follows your current device’s appearance setting

The theme change takes effect immediately and is saved to your account, so it will apply across all your devices.
