I am a retired Project Manager and developer of PDF2box (PDF Toolbox), StatBoard is another app of mine on the App Store for more than a year.
A
StatBoard shows live CPU, memory, battery, storage, and network stats on iPhone. It also includes 20+ network utilities (ping, DNS, port scan, LAN, HTTP, certs, and others) and local file tools. No ads, no analytics SDKs.
B
If you use a stats widget for monitoring and a separate app for network checks, StatBoard puts both in one place with one time purchases instead of a subscription.
C:
Free to download. The main dashboard is free. Network Tools and System Tools need Pro Pack or the 7 day trial. In App Purchases: Enable Pro Pack ($4.99). One time purchases, not a subscription.
