SysReadout Monitor

Everything your Android phone will tell you about itself, drawn as a KDE Konsole terminal.

SysReadout Monitor (SR Monitor) groups hardware, CPU, memory, power, network, radio signals, apps, sensors, storage, a live event journal and a shell into pages you swipe between. Each page looks like a Konsole session on Fedora: Breeze colours, the Hack font, a bash prompt, and colour only where it means something.

It works only while you look at it, and only for the page on screen, so it costs nothing the rest of the time. Forked from SysReadout Launcher, which shows the same data on the home screen.

Pages

Tab	What it shows
sys	device, chipset, GPU, display; Android build, fingerprint, security patch and its age, Play system update, encryption, verified boot, SELinux; kernel build, bootloader, baseband; WebView and Play services versions; uptime
cpu	per-core meters, load, thermal status, every temperature sensor, busiest processes
mem	RAM and swap meters, memory detail, processes by memory
power	battery meter, voltage, current, watts, charger, cycles, capacity; with Shizuku drain since the last charge (screen on/off, doze), time left, use by part and by app, wake locks
net	connection, Wi-Fi and mobile signal in words, IP, serving cell, 5G / LTE-CA, traffic, connections per app with server names, DNS lookups per app
scan	every Wi-Fi access point and Bluetooth device with its signal in dBm and %, how steady it is, and whether it's getting stronger; tap a device to track it and find it
apps	screen time, unlocks, notifications per app, running foreground services
sensors	environment sensors, compass, GPS and every satellite, sun and moon, steps, Bluetooth devices, audio, what's playing
storage	storage meters, file systems, biggest apps
journal	a live event log: network, power, installs, app switches, processes, connections, logcat errors, DNS lookups, notifications
shell	type commands and see their output; as the shell user with Shizuku
conf	all settings as a config file, and what each access is for

Install

• F-Droid: submitted, waiting for review (fdroiddata!50817).
• GitHub: download SysReadout-Monitor.apk from the latest release and open it (allow "install unknown apps").

Requires Android 8.0 (API 26) or newer.

Permissions

Nothing beyond the basics is used until you tap the thing that needs it, and runtime permissions are requested at that moment.

Permission	Used for	When
Network state, Wi-Fi state	connection type, IP, Wi-Fi signal	install-time, no prompt
Query all packages	real app names for processes, connections, traffic and app counts	install-time
Internet	only the optional DNS monitor, which relays your apps' own lookups to your DNS server	only if you switch it on
Usage access	screen time, traffic, app sizes, app and screen events	you grant it in Android settings
Notification access	notification counts and events, what's playing	you grant it in Android settings
Location	GPS, satellites, Wi-Fi name, networks nearby, serving cell, sunrise	asked when you tap it
Phone	5G / LTE-CA link details	asked when you tap it
Nearby devices (Bluetooth scan)	Bluetooth signal on the scan page; never used for location	asked when you tap it
Bluetooth connect	connected devices, their battery, tracked device signal	asked when you tap it
Physical activity	steps	asked when you tap it
Bluetooth, Bluetooth admin (Android ≤ 11)	Bluetooth state and scanning on old Android	install-time on old Android
Shizuku (optional)	processes, connections, per-core load, temperatures, wake locks, battery use per app, logcat, the shell as shell	a guided setup in conf › [shizuku]

Privacy

No ads, no analytics, no tracking, no accounts. Everything is read on the phone and kept in memory while the app runs; only your settings are stored. Nothing is sent anywhere: the only network use is the optional DNS monitor passing your apps' own lookups on to the DNS server your network names (never to a public resolver of our choosing), and optional reverse-DNS lookups of connection addresses.

Build

Requirements: JDK 17 or 21, Android SDK (compileSdk 36).

./gradlew :app:assembleDebug :app:lintDebug :app:testDebugUnitTest

The Gradle root is the repository root; the app module is app/.

Release signing

Release builds are signed from a keystore.properties file at the repository root, which is not in git:

storeFile=/absolute/path/to/sysreadoutmonitor-release.jks
storePassword=…
keyAlias=sysreadoutmonitor
keyPassword=…   # PKCS12 keystores: same as storePassword

Without it, assembleRelease leaves the APK unsigned, as F-Droid's build server expects. CI gets the same values from repository secrets (RELEASE_KEYSTORE_B64, RELEASE_KEYSTORE_PASSWORD, RELEASE_KEY_ALIAS, RELEASE_KEY_PASSWORD).

Releasing a version

1. Bump versionCode (+1) and versionName in app/build.gradle.kts.
2. Add metadata/en-US/changelogs/<versionCode>.txt.
3. Commit and push to main; CI publishes a rolling latest release.
4. Put the full hash of that commit into .fdroid.yml (commit:), update versionName, versionCode, CurrentVersion, CurrentVersionCode, commit and push.
5. Tag the release commit vX.Y.Z and push the tag. release-tag.yml publishes a permanent release whose SysReadout-Monitor.apk is what F-Droid compares its own build against (Binaries, AllowedAPKSigningKeys in .fdroid.yml).
