TL;DR:
A complete and detailed app to see the details of what your device is doing, its attributes and current settings that doesn't bombard you with ads or phone home to a gazillion 3rd parties. Aimed towards more techie, but can be used by all; just half the fields might not be helpful for you

I plan for a premium one-time in-app upgrade later in the future for development support and nice-to-have features like real-time updates, exporting data etc.

Current functionality:
- Network - list all network interfaces (if it's connected, it will be listed such as VPNs, Wi-Fi, Cellular etc.) and all SIMs/carriers (both physical and eSIM)
- Battery - statistics and properties including charging, voltage and health

Future functionality (in development or to come at a later date):
- Device Specs (what's stored on the device or available via Android APIs)
- CPU & Memory
- Display & Graphics
- Connectivity (Bluetooth, NFC etc.)

Backstory:
I originally was annoyed I couldn't find an app to display all of my networks or it would but wouldn't show both SIMs, maybe it'd only show the currently active network interface but not the others even though they are still connected and being utilised... grrr; so what started as a self-satisfying app has turned into this app that others can also utilise.

Notes:
- Currently under development, new features, views etc. will drop in regular intervals
- The intention of this app isn't to change/alter/modify, delete or add but to give you a clear insight into the corresponding views (battery, networks etc.) and their values

Permission explanations:
'ACCESS_NETWORK_STATE' - ability to check if connected to the internet and list network interfaces
'READ_PHONE_NUMBERS' and 'READ_PHONE_STATE'- required to list SIM/eSIM properties and phone numbers (not required, you have to enable this permission)
'carrier privileges' - required to access transport and carrier details info such as carrier name etc.
'BILLING' - ability to purchase premium and restore purchases (not required, helps support development)
'ACCESS_FINE_LOCATION', 'ACCESS_COARSE_LOCATION', 'ACCESS_WIFI_STATE' - literally to be able to resolve WiFi AP names, BSSID, you will notice location isn't actually asked for just the permission

FAQ:
Q1 - With the data displayed in the app what do you do with it?
A1 - Other than displaying it in the app, nothing, there is no reporting, no sending, no uploading or anything like that

Q2 - You ask for some elevated permissions, why?
A2 - See "permission explanations" for a detailed answer but essentially the Android APIs are complicated and complex (maybe a bit too much), for example, you need access to Location to be able to see Wi-Fi SSIDs; why, I don't know, maybe there are some reason(s)

Q3 - Will you add the ability to change these settings/values displayed?
A3 - Nope, this is a "looking through the window" approach, display and report. There will be shortcuts to the relevant settings pages but the app won't touch them

Q4 - Can I suggest a feature or help, something is broken or not reporting correctly, how can I tell you?
