About

Corps Protect

Features
Read full description

Corps Protect is more than an app, it is a 24/7 personal security service. Corps Protect is activated by simply shaking or tapping the smartphone. This immediately sends an alert notification to CorpsSecurity and designated emergency contacts via SMS and email detailing an exact GPS location. Personnel working in a wide variety of industries – from transport and finance to local councils and healthcare – can take advantage of Corps Protect. The ability to turn a phone into a safety device also negates the purchase and use of traditional personal alarm systems, which makes it highly cost effective. Users can log into the Corps Protect website to manage their accounts, update their profiles and view all of their alerts. They can also diarise their activities so that colleagues, family and friends can find out where they will be at any given time. For example, an estate agent that is due to show a potential purchaser around a house can arrange for a notification to be sent after the meeting is due to finish. If the alarm time needs to be extended a simple push of a button can postpone it in 15-minute intervals. Continued use of GPS running in the background can dramatically decrease battery life.

See how your device moves with Acc.elerometer. View live sensor readings, record an experiment and examine the results on your iPhone or iPad. Capture motion on Apple Watch and send recordings to your paired iPhone for charts and CSV export. EXPLORE SIX MEASUREMENTS - Acceleration, including gravity, in G - User acceleration, with gravity removed, in G - Rotation rate around three axes in rad/s - Magnetic field in microteslas - Device attitude: roll, pitch and yaw in radians - Gravity along each axis in G View individual axes and vector magnitude where supported. Follow changing values and review recorded measurements to explore movement, rotation and orientation. RECORD AND REVIEW Choose the measurements you want to capture, then start and stop a recording. On iPhone and iPad, set the measurement interval from 0.1 to 1 second. Open saved recordings to inspect charts, switch between individual axes and vector magnitude for supported measurements, and identify gaps in the data. EXPORT YOUR DATA Export each measurement from a recording as a CSV file with timestamps and axis values. Choose Unix time, spreadsheet serial dates or formatted date strings for your analysis workflow. CAPTURE MOTION ON APPLE WATCH View sensor readings and record selected measurements on your wrist. Send saved recordings to the paired iPhone and follow transfer progress. Add watch face complications to see saved sensor maxima or recording status, and open the app to start a recording from the recording widget. FOR EXPERIMENTS AND EVERYDAY CURIOSITY Explore device motion for a physics demonstration, a development project or your own experiments. Measurements and recordings are stored on your devices. No account is required. Available readings and actual sampling intervals depend on the device and its sensors. Apple Watch recording duration is subject to watchOS background runtime limits. Watch complications show saved values from the app, rather than a continuous live sensor feed.
