Featured Instruments
Six tools that define what makes DeviceLab Tradesman the go-to diagnostic and field instrument platform.
Digital Protractor
Camera-overlay angle measurement with sensor-assisted precision. Lock and save measurements, switch between multiple display modes, and capture exact angles for cuts, installations, and alignment work on the job site.
Thermal Monitor
Real-time CPU, battery, and skin temperature tracking with configurable warning thresholds. Health alerts when your device overheats during demanding field work. Temperature history with trend visualization.
Floating Monitor
Always-on-top overlay widget showing live CPU, RAM, battery, and network stats. Draggable, customizable, and designed for field technicians who need system visibility while running other apps.
Storage Analyzer
Visual storage breakdown by category with large file detection and duplicate finder. Color-coded usage charts, per-app storage consumption, and one-tap cleanup for cache files eating your space.
Device Benchmark
Single-core and multi-core CPU scoring, GPU performance tests, and storage speed benchmarks. Compare your device against baselines to verify hardware health before critical field deployments.
Charts Dashboard
Historical performance visualization with battery trends, CPU load patterns, memory pressure graphs, storage changes, and temperature curves. Selectable time ranges from hours to weeks of data.
Technical Specifications
Built with Kotlin and Material Design 3, backed by Hilt dependency injection, SQLCipher-encrypted Room database, and WorkManager for reliable background monitoring.
Your Device Stays Private.
Your Data Stays Encrypted.
DeviceLab Tradesman processes all diagnostics and measurements entirely on your device. Health snapshots and sensor data are stored in a SQLCipher-encrypted database that never leaves your phone.
No cloud uploads. No remote telemetry. No device fingerprinting. Your system data, benchmark results, and field measurements are exclusively yours.
100% Local Processing
All diagnostics, sensor measurements, and system analysis happen entirely on your device. No data is ever transmitted to external servers.
Encrypted Database
Health snapshots, usage records, and measurement data are stored in a SQLCipher-encrypted database. Your device data is protected at rest.
No Account Required
Full functionality from first launch. No sign-up, no email, no phone number. Every tool works immediately out of the box.
Minimal Permissions
Permissions are requested in-context only when you use a feature that needs them. Camera for protractor, microphone for decibel meter — nothing more.
No Cloud Sync
Your system health data, benchmark results, and exported reports stay exclusively on your device. No cloud uploads, no remote storage.
GDPR / CCPA Compliant
Full consent management via Google UMP SDK. Transparent data practices with user control over ad personalization and data preferences.
