## Description

Before you build an app or a device, check whether the phone can actually produce the signals it will depend on.<br><br>A spec sheet may list a sensor, but whether it reports values, how often, and how accurately varies from handset to handset. Sensor Checker shows you.<br><br>■ Two ways to use it<br><br>Situations - pick one of ten situations (on a boat, coastal walking, work at height and more) and the required sensors and sampling rate are set for you. You see at a glance whether this phone is enough for an app built around that situation.<br><br>Single sensor - turn on any of 18 sensors one at a time and watch its value and waveform. Nothing is recorded, so you can explore freely.<br><br>■ Display that fits the sensor<br><br>Heading appears as a compass, tilt as a spirit level, cellular strength as signal bars, position on a map. Not just rows of numbers.<br><br>■ Signals you can check<br><br>Location - latitude/longitude, altitude, accuracy, speed, satellite count<br>Cellular - signal strength (dBm), bar level<br>Motion - acceleration, linear acceleration, gravity, gyroscope<br>Attitude - heading, pitch and roll, magnetometer<br>Environment - barometric pressure, relative altitude, light, proximity<br><br>■ Export to Excel<br><br>Save a session as an xlsx file. Alongside the raw values it includes a sheet explaining every column, its unit, and the grading thresholds, so whoever receives it can read it without asking you.<br><br>■ Your data never leaves the device<br><br>Measurements are stored only on this phone. Nothing is uploaded. No accounts, no ads, no analytics SDKs.<br><br>■ Four languages<br><br>Korean, English, Chinese and Japanese. Switch any time inside the app; the Excel export follows the language you chose.<br><br>■ Not a safety device<br><br>This app does not detect or report accidents. It is a development and evaluation tool for checking what signals a handset can produce. Do not rely on it where safety is at stake.
