Five focused tabs
Dashboard, Hardware, System, Apps, and Tools keep the experience organized while still surfacing live battery, RAM, CPU, network, diagnostics progress, and deeper utilities.
Modern device diagnostics
Understand your Android device at a glance.
Device Info combines live battery, RAM, CPU, network, and thermal status with detailed hardware inspection, installed-app risk signals, Wi-Fi Analyzer, Floating Monitor overlay tiles, Hardware Tests, Sensor Lab, customizable PDF reports, and six home-screen widgets.
- Tools hub
- Wi-Fi Analyzer
- Floating Monitor
- Free and ad-free
One clear device workspace
Built with Jetpack Compose for Android 11 and newer, with dark and light themes, live status cards, fast tab switching, full-screen tools, and user-started overlay monitoring.
Overview
Built to explain device health, software state, and app behavior without the clutter.
Read-only system inspection is paired with practical tools, live diagnostics, and explainable security indicators, helping users understand the device without turning the experience into a wall of raw specifications.
Hardware and software depth
Inspect Android and build details, CPU cores, memory, storage, display, battery, thermal state, network addresses, camera capabilities, sensors, NFC support, and device features.
App inventory and risk visibility
Browse installed apps with search, source details, version data, install timestamps, size formatting, and factual capability-based risk signals.
Tools hub
The Tools area links into Floating Monitor, Wi-Fi Analyzer, Hardware Tests, and Sensor Lab so users can move from live overlays to detailed diagnostics without hunting around.
Features
From a quick health check to a report you can keep.
Wi-Fi Analyzer
Scan nearby networks, compare signal strength, band, channel, width, security, vendor, and estimated distance, then review live RSSI and least-congested channel guidance.
Floating Monitor
Start draggable overlay tiles for FPS, RAM, battery, network throughput, and storage so key device metrics stay visible while using other apps.
Custom 14-section PDF reports
Choose from overview, hardware, system, CPU, memory, battery, thermal, network, display, camera, sensors, apps, security, and diagnostics sections before saving a report.
Live Sensor Lab and fingerprint check
Review sensor health, recent readings, and waveform-style feedback, or launch Android's secure biometric prompt to verify fingerprint hardware.
Guided Hardware Tests
Run visual, camera, speaker, earpiece, microphone, flashlight, vibration, button, NFC, Bluetooth, Wi-Fi, location, charging, and connectivity checks. Saved status survives app restarts.
Explainable app risk indicators
Source-aware checks look at active high-risk capabilities, granted permission combinations, and curated allow or block signals without calling heuristics proof of malware.
Six home-screen widgets
Keep RAM, device summary, battery, storage, CPU and temperature, or network details on the home screen. Widgets refresh automatically and support immediate manual refresh.
Memory, camera, and thermal tools
Open dedicated memory diagnostics, inspect each detected camera through Android's Camera2 API, and monitor live thermal throttling state alongside CPU information.
In The App
The current product map is wider than just device specs.
The main five-tab shell stays simple, while dedicated screens handle deeper workflows such as Wi-Fi scanning, floating metric overlays, memory diagnostics, hardware tests, sensor monitoring, and required app updates.
Dashboard
Quick summaries, reactive battery, RAM, CPU, network, and thermal cards, plus PDF export.
Hardware
Device identity, CPU, memory, display, battery, cameras, sensors, and feature support.
System
Android version, build details, patch level, kernel, connectivity state, and runtime environment information.
Apps
Installed package inventory with source, size, install history, permission signals, and capability-based risk visibility.
Tools
A hub for Floating Monitor, Wi-Fi Analyzer, Hardware Tests, and Sensor Lab.
Focused tools
Memory diagnostics, sensor metadata, fingerprint testing, NFC checks, app-update handling, widgets, and Play review flows round out the core tab experience.
Privacy
Clear permission and data-use language for Google Play review.
The policy covers on-device inspection, installed-app visibility, Wi-Fi scanning, floating monitor overlays, Firebase services, Android backup behavior, PDF exports, widgets, diagnostics, biometric testing, update checks, and every permission declared by app version v6.0.0.
Most device information, Wi-Fi scan results, and overlay readings stay on the device.
The app does not contain ads and explicitly removes advertising-ID permissions.
Installed package names, nearby network lists, and generated PDF contents are not uploaded by the app's own code.
