Sensor Lab: Sensor Test Tools
Test your phone's sensors: compass, meters, metal detector, QR & CSV logger
About Sensor Lab: Sensor Test Tools
Sensor Lab is an all-in-one sensor test toolbox that turns your phone's built-in sensors
and hardware into simple, honest tools. No clutter and no fake readings — just clear,
live data you can actually use, plus a multi-sensor data logger for when you want to
record it.
Whether you're a student, maker, DIY tinkerer, or just curious what your phone can
measure, Sensor Lab puts 15 tools in one clean app.

📊 SENSOR LOGGER
The standout feature: record multiple sensors at once to CSV. Choose your sources and
sample rate, watch a live chart while it runs, then open, rename, share or export your
logs. Perfect for science projects, experiments and motion analysis.
🔒 YOUR DATA STAYS YOURS
Sensor readings and recordings are processed on your device and saved only inside the
app — we never upload them. Ads use a standard Google advertising ID; that is the only
data that leaves your phone.
✅ HONEST BY DESIGN
Readings depend on your specific phone's hardware and are meant for everyday,
educational use — not certified measurement. The heart-rate tool is for fun and is NOT a
medical device. The metal detector senses changes in the magnetic field around your phone.
Free to use with ads. A one-time "Remove ads" purchase unlocks an ad-free experience —
no subscription.
Download Sensor Lab and explore everything your phone can sense: compass, sound meter,
light meter, metal detector, bubble level, QR scanner, flashlight, device info and a full
sensor data logger.
