I used to have Du-meter app to track the bandwidth status (upload / download sped) from the topbar, but it was discontinued some years ago.
I recently saw someone in a video call using an interesting app to track not only bandwidth, but other indicators such as CPU usage, Memory usage, etc. At least, I was able to capture a screenshot:
Zoomed shot of relevant area
I tried to find system & network applications within the App Store, but most of them are old and not updated.
Is anyone able to recognise the app from the screenshot?
