Where are the settings in the app?
The gear in the bottom-right corner of the map, opposite the account button on the left. The menu has four sections: “Appearance”, “Language”, “Backups” and “About”.
Changes apply immediately — there is no “Save” button. The map behind the menu is not blurred, so you see a new theme while you are choosing it.
“Appearance” is a Premium feature: without a subscription the section opens, but its settings are locked. “Language”, “Backups” and “About” are available on any plan. “About” gathers quick links: selecting the mock location app in developer options, the app's system permissions (location, notifications, battery), the website with guides and support, and the installed version number.
Starting spoofing, search, lock mode and rotating the map to the direction of travel are not in the menu: they are actions, not settings, and they stay on the main screen. An overview of the whole menu is in the guide on the app settings.
