The way you change the language depends on your platform.

iOS / iPadOS

On iPhone / iPad, the app language is controlled by the iOS system settings, not from inside the app. Each app has its own per-app language setting.

1. Open the iOS Settings app.
2. Scroll down and tap Monitor+ in the list of apps.
3. Tap Language (Language / Preferred Language).
4. Choose your desired language from the list.
5. Return to Monitor+ — it will now display in the selected language. (If the app is already running, fully close and reopen it to apply the change.)

Tip: If the language you want is not shown in the list, add it first under Settings → General → Language & Region → Preferred Languages, then repeat the steps above.

Android

On Android you can change the language directly inside the app, and it takes effect immediately — no restart required.

1. Open Monitor+.
2. Go to the Preferences tab (the settings/preferences section).
3. Find the Language option.
4. Tap it and select your desired language from the list.
5. The app updates to the new language right away.

By default the app follows your Android system language. Selecting a specific language here overrides that and is remembered for next time.
