Daily space intelligence
Answers, not just sensor numbers.
FieldLens combines sound, motion, magnetic, light, pressure, speaker, and time-based readings to answer the practical questions people actually have.
Is this space good?
A fused space score summarizes whether the current environment looks usable, usable with checks, or worth scanning before relying on it.
What changed?
FieldLens compares the current fingerprint against previous scans and highlights sound, motion, magnetic, light, or pressure changes.
What should I check?
The top card explains the main concern and uses cross-sensor clues, like sound plus motion or magnetic plus motion, to reduce guesswork.
At a glance
sensor channels: sound, speaker, magnetic, motion, light, pressure, and thermal pathways
space scan that combines runnable tests into a useful report
exportable reports with date, time, location, device stamp, and findings
Pocket field lab
Single-sensor checks and combined-sensor insight.
Sound and tone
Estimate room sound, watch tone output, and use speaker plus microphone as a controlled wave experiment path.
Motion and stability
Use accelerometer and gyroscope data to notice vibration, handling, impacts, and surface stability.
Magnetic field
Find magnetic hotspots near electronics while clearly separating phone magnetometer data from RF or electric-field claims.
Light and pressure
Check work-ready light, dim spaces, pressure context, elevator/stair changes, and sealed-container demos.
Reports
Scan history that becomes more useful over time.
Every report is a line item. Open it for the full result, export just that report, or export the full report library.
Daily space brief
Live signal evidence
Collapsed report list
Individual report export
Play Store
Prepared for Android submission.
Listing focus
Scan invisible signals around you with the phone sensors you already own. FieldLens is for everyday rooms, surfaces, sounds, and field-lab curiosity.
Trust boundary
FieldLens is educational and informational. It does not replace professional sound meters, RF meters, medical testing, or safety-certification equipment.
