The new app Lockdown provides a privacy-focused firewall for your iPhone that can block any internet domain.
After downloading the app, you can block any connection to a specific domain. To help you get started, there are also some default settings.
And there’s no need to worry about privacy or security when using the app. Lockdown is open source and operates completely on the device. That means no data or personal information is ever sent to another server.
Just to note, while the app uses Apple’s built-in VPN feature, Lockdown isn’t a VPN.
Lockdown is designed for the iPhone and can be downloaded now on the App Store for free.
A Mac, PC, and Android version of the app is promised soon.
