Senscoder / Android

Your phone already knows more than it shows.

Turn the sensors inside your Android device into a focused field instrument. Read position, motion, vibration, sound, magnetic fields, atmospheric conditions, local radio signals, NFC tags, and the sky — with every calculation kept on the device.

01 / Instruments

Eleven ways to read the world around you.

Each view is purpose-built, activates only the hardware it needs, and supports missing sensors as a normal device state.

01 / Navigation

Navigation

Steady compass heading, GPS position, speed, accuracy, pressure, and estimated altitude — with honest stale-fix states when reception drops.

CompassGPSBarometer

02 / Map

Offline map tracking

A responsive vector globe with coastlines, borders, rivers, lakes, cities, and real airport runway directions — all packaged with the app.

No signal neededLive positionNo track recording

03 / Dynamics

Dynamics

Velocity, direction, linear acceleration, G-force, and a calm 15-second rolling history with adaptive scale.

MotionG-force

04 / Seismograph

Seismograph

Live three-axis vibration, peak hold, combined FFT analysis, and grouped dominant frequencies. Not a calibrated seismometer.

AccelerometerGyroscope

05 / Astronomy

Astronomy

Offline sky positions, rise and set events, lunar phases, planetary events, and an interactive observer globe.

EphemerisOffline globe

06 / Sound

Sound analysis

Multichannel dBFS levels, oscilloscope, spectrum, three dominant peaks, and waterfall analysis from 20 Hz to 20 kHz.

dBFSFFTForeground mic

07 / Magnetic

Magnetic field detector

Field strength, axis components, direction, and fluctuation with five-second averaged readouts and a fluid live 3D vector sphere.

Magnetometer3D vector20 s trace

08 / Environment

Environment

Ambient light, pressure, estimated elevation, proximity, acceleration load, and magnetic field — every available device sensor presented without invented substitutes.

Live readingsPartial hardware supportedNo fake temperature

09 / Wi-Fi

Wi-Fi instrument

Local link telemetry, RSSI history, nearby access points, colored 2.4/5/6 GHz channel views, security metadata, and supported Wi-Fi RTT ranging — without internet traffic.

Channel viewSignal tracesNo speed test

10 / Bluetooth

Bluetooth instrument

A user-started 12-second BLE scan with per-device signal traces, strength bars, filters, advertisement details, and the phone's reported radio capabilities.

Foreground BLENo pairingNo distance claim

11 / NFC

NFC inspector

A strictly read-only foreground inspector for tag technologies, identifiers, capacity, and cached NDEF text, URI, MIME, or external records.

Read onlyNo link openingLocal data

02 / Screens

A field instrument, not a generic dashboard.

Fifteen fresh, full-screen captures from the current app. Swipe through them, use the arrow controls, or open any screen for a closer look.

03 / Principles

Built to measure your world. Not your behaviour.

Privacy is architectural, not a settings toggle. Senscoder has no internet permission, account system, analytics, advertising, or background location.

Offline by architecture

Maps, astronomy data, analysis, and every calculation ship with the app and run locally. Airplane mode changes nothing.

Permission-scoped

Location and microphone access are requested only where required. Hardware is active only for the visible destination.

Measurement-honest

Unavailable hardware stays unavailable. Sound is reported as dBFS, not invented dB SPL, and consumer sensors are never presented as calibrated equipment.

Native and accessible

Kotlin, Jetpack Compose, responsive layouts, semantic controls, dark and light palettes, and supported missing-permission states.

01 / InputDevice sensors

Read only for the active instrument.

02 / ProcessLocal analysis

Filtering, FFT, maps, and astronomy stay on-device.

03 / OutputYour display

No server path, telemetry event, or cloud copy.

Measurement principle

Senscoder presents best-effort readings from consumer-device sensors. Values depend on hardware, calibration, placement, environment, and manufacturer processing. It is not calibrated measuring equipment and must not be used for medical, safety, legal, or compliance decisions.

Independently built / useful by default

A field kit already in your pocket.

Senscoder is still being prepared for release and will then be offered as a paid app through Google Play. The app itself requires neither network access nor a Senscoder account.

Coming soon as a paid Android app
