Opal lets you prevent yourself from uninstalling Opal or other apps while you're blocking apps in a session (works for all session difficulties). When enabled, you can't remove ANY app without stopping Opal blocking first, you may only remove apps from your home screen.
Navigate to Settings and enable "App Uninstall Protection" under "Blocking Preferences"
Please note: App Uninstall Protection can not be disabled while you are in a Deep Focus session.
With a combination of app restrictions, real time feedback and rewards, you can begin to focus better and accomplish your dreams.
