Where to find it
Settings → Appearance.
Theme styles
- Tellmint (default): mint green primary with an amber accent. Modern and product-y.
- Warm Paper: warm beiges and browns. Softer, journal-like feel. Often chosen for reading-heavy moods.
- Monochrome: clean high-contrast neutrals with a single teal accent. Minimal and accessibility-forward.
Each style respects your light/dark preference independently, you can, for example, use Warm Paper in dark mode or Monochrome in light mode.
Light / Dark / System
A visual card picker lets you choose:
- Light: always light.
- Dark: always dark.
- System (default), follows your phone's theme automatically.
How changes apply
- Theme changes apply instantly. The UI updates locally before the cloud acknowledges the change.
- If a save fails for any reason, the app gently reverts.
Vibration feedback
Vibration feedback now lives under Settings -> More settings -> Vibration, just below Personalization. (It used to sit near the top of Settings; it moved here in May 2026 because it's a set-and-forget control most people only touch once.)
- Vibration feedback is on by default. Buttons, recording actions, and newly saved entries vibrate gently.
- Test vibration lets you check whether the app can trigger vibration on your phone.
- On Android, Phone vibration opens the closest system screen, usually Sound & vibration, because phone makers do not expose one universal deep link to the exact toggle.
If Test vibration does nothing, check your phone's own setting. On Xiaomi/POCO/HyperOS phones it is sometimes still labelled Haptic feedback at the system level (Settings -> Sound & vibration -> Haptic feedback), even though Tellmint now calls it Vibration to match how most people talk about it.
Other appearance controls (Advanced)
Under Settings → Advanced → Appearance:
- First day of week: Monday by default. The setting exists in this section but the calendar view is currently hard-coded to start on Monday regardless.
Good to know
- Font consistency. Every theme uses the same typographic system, only color, accent, and surface treatments change. No theme changes the text size or spacing.
- Pattern Sky has its own fixed look: the sky uses a dedicated dark palette in every theme, not the active app theme.
- PDF export themes are separate. When you export a Mint Edition, you pick a PDF theme independently of your in-app theme.
