How to choose your preferred language in the app's settings on your device.
Go to your phone's Settings:

Choose the preferred language:
After that exit the phone's settings and reopen Simple. Your preferred language must be added to your device's Language list in iOS Settings first.
If you're not seeing the option to change the language in the Simple app on iOS, you may need to adjust your iPhone’s settings first. You'll need to add the language to your iPhone.

Tap Language & Region.
Tap Add Language...
Choose the language you want to use.
Tap Use [New Language] to make it your primary language, or
Tap Keep [Current Language] to keep your current one and add the new one as secondary.
After this, you can then change the Simple app’s language:
In your iPhone Settings, scroll down and tap on the Simple app.
Tap Language.
Choose your preferred language from the list.
Reopen the Simple app — it should now appear in the selected language.
