Pi ContrHOLE is a free, unofficial app designed for iPhone users to manage their Pi-Hole instances remotely. This utility tool allows users to connect to their Pi-Hole by IP address, providing quick access to essential statistics such as cumulative ads filtered and the percentage of ads blocked. Additionally, it features a list of recently connected devices and the ability to store session keys, ensuring seamless management of network settings.

The app enhances user experience with functionalities such as toggling settings on the local Pi-Hole instance, enabling or disabling it to troubleshoot DNS issues, and scheduling toggles for specific periods. Supporting two Pi-Holes concurrently, Pi ContrHOLE is designed with dark mode compatibility and offers convenient access through long-press app icon options. Users must have an active Pi-Hole instance and API key for full functionality.
