Pi Stats also supports Pi Monitor* which enables you to see even more detailed data from your Pi-holes like temperature, memory usage, uptime and load average
If you have Pi Stats for macOS, you can easily import your Pi-holes scanning the QRCode generated by the Pi Stats for macOS.
Pi Stats do not track anything you do and its a 100% open source app, you can check it out on the Support URL.
