Tase - Sound Meter & Tools

Tase turns your phone's sensors into three measuring tools with a shared journal: a sound level meter (dB), a vibration meter and a light meter (lux). Every recording can be saved with a note, tags, a photo and location, and exported as CSV or a PDF report. Works fully offline.

SOUND METER (dB)

• A-weighted sound level with Fast (125 ms) and Slow (1 s) time weighting

• Min, average, max and Leq (equivalent continuous level) for the session

• 30-second history graph and reference scale (quiet room, office, street, power tools)

• Overload indicator — the app tells you when the phone's microphone hits its limit instead of showing a wrong number

• Calibration against a reference meter; the offset is written into every recording

• Audio is never recorded or stored — only the level values

VIBRATION METER (m/s² or g)

• RMS and peak acceleration on three axes and magnitude

• FFT spectrum with the dominant frequency, up to your sensor's sampling limit

• Sensitivity threshold is zero by default — weak vibrations are not hidden

• Hint when the phone is held in the hand instead of placed on the object

LIGHT METER (lux / fc)

• Illuminance from the ambient light sensor, median-filtered for a steady reading

• Reference values for rooms and tasks based on EN 12464-1 (corridors, offices, workshops, fine work)

• Shows the sensor's step size and range so you know what the number means

JOURNAL AND EXPORT

• Start/stop recording on any tool; the series is saved, not just one number

• Add a note, tags, a photo (via the system camera) and, optionally, your location — all stored only on this device

• Export a recording as CSV (summary and full series) or as a PDF report with the graph, conditions and calibration

• Export is free and unlimited

YOUR SENSOR

Before the first measurement Tase shows what your device actually has: microphone source and sample rate, accelerometer rate and range, light sensor resolution. Phone sensors are not laboratory instruments, and Tase says so instead of pretending.

DESIGN

• Dark theme by default, light theme for direct sunlight, or automatic switching by ambient light

• Large monospaced readings, high contrast — made for workshops, sites and outdoors

• No ads over the system navigation bar, no forced sign-up, no subscription

PRICE

Tase is free with a small banner ad. One one-time purchase removes ads forever. Nothing else is locked.

PERMISSIONS

• Microphone — sound meter only; nothing is recorded

• Location — only if you turn on "Add location" for journal entries; never leaves the device

• No camera permission: photos are taken by your system camera app

• No internet use except ads and the purchase

Measurements made with a smartphone are indicative and are not a substitute for a certified measuring instrument.
