Key Pain Point: Power users and field professionals needed a single app replacing five or more fragmented utility tools.
We engineered Epheos Scan as a unified power-user toolkit using Jetpack Compose, CameraX, ARCore, and hardware sensor APIs. It delivers high-speed camera QR/barcode parsing, on-device ML Kit OCR, AR 3D spatial measurement with polyline area and volumetric box estimator, a digital spirit level & clinometer, real-time decibel meter, PCM audio synthesizer, construction material estimators, NFC/RFID tag cloning, BLE & Wi-Fi network discovery, Quick Settings tiles, a unified history engine with cloud sync, and zero ad tracking.
ARCore visual-inertial odometry powered real-time 3D distance, polyline perimeter, surface area (m²/ft²), and volumetric box (m³/ft³) measurements without requiring external hardware.
The clinometer leveraged device IMU sensors to measure slope angles, roof pitches, ramp gradients, and building heights through camera trigonometry.
A PCM waveform synthesizer (Sine, Square, Sawtooth, Triangle) with a 20 Hz–20 kHz frequency slider provided real-time audio tone generation for acoustic testing.
Epheos Scan has evolved from a focused scanning utility into a comprehensive engineering and diagnostic super-app for Android. Built natively with Jetpack Compose, CameraX, and ARCore, it unifies seven distinct toolkits — multi-protocol hardware scanning, on-device OCR, AR spatial measurement, digital spirit level & clinometer, decibel & audio synthesis, construction calculators, and cloud-synced history — into a single, privacy-first, ad-free application.
Our research revealed critical insights that informed our strategy and implementation.

The decibel meter tracked real-time dB, Peak dB, Min dB, and Average noise with automatic safety badges (Quiet / Normal / Loud / Very Loud).
Construction calculators covered paint bucket estimation, concrete volume, drywall sheet counts, rafter lengths, pitch ratios, tape measure fraction conversion, and a live currency unit converter.
On-device ML Kit text recognition delivered live OCR on camera view, documents, and images with word/character count inspection — no cloud upload required.
Isolated cloud sync used UUIDs and single-record delete safeguards to prevent history overwrites, while local File.exists checks ensured annotated photo reports remained valid.
Jetpack Compose enabled rapid UI iteration across all seven toolkits with consistent theming, smooth modals, and edge-to-edge display.
Epheos Scan demonstrates that a disciplined, unified architecture can replace an entire suite of fragmented utility apps without sacrificing privacy, performance, or cost accessibility. By combining AR measurement, audio analysis, hardware scanning, OCR, and construction calculators into a single Jetpack Compose application with optional cloud sync, it delivers a genuinely differentiated tool that grows with the user.
