BrakeTest

BrakeTest is a performance meter designed to test the braking performance of your vehicle. In use it displays a braking gauge to monitor performance and the speed. When performing a test the results can be displayed on screen and are stored in a CSV file for easy export if further analysis is required. A PDF summary of the test is also created. Both types of file can be accessed through the Files view or the internal history database. Designed originally for LGV/PSV brake testing, BrakeTest can be set to perform any type of brake testing using the standard DVSA or FMCSA categories. The Pro version adds in emergency or park braking tests. A Forensic test setting is also provided for maximum flexibility which is ideal for collision investigation purposes or ad-hoc brake tests. For forensic collision investigation purposes, the Pro version allows a series of tests to be selected to perform a statistical analysis of the selected items and generate a confidence interval for the results. Confidence levels of 90%, 95% and 99% are written to a PDF file. The default calibration of the accelerometers on your iPhone are likely to generate test results within 1 - 2% of the true value. In the Pro version the iPhone can be calibrated by the user to check the accuracy of the built in accelerometers. To use BrakeTest, your device should be securely mounted in the vehicle with the screen oriented so that the on-screen text and gauges are approximately perpendicular to the direction of travel. The device doesn't have to be perfectly level, approximately level is fine. Drive to the area where the test is to be performed and press the Reset button to level the device to the road. The Reset button can also be used to re-orientate the device at any time and is best performed when the vehicle is stationary. This avoids any bumps in the road distorting the calibration. You can change the type of vehicle you want to test using the Select Test Type screen which can be accessed by pressing the Menu button. For Brake tests press the Start / Arm button when you are ready to begin the test and perform the test. You can press the Arm button at any time, even when the vehicle is in motion. The results will be displayed automatically once the test is complete and includes two seconds of data prior to the start of the test and a short time after the test has finished. The limits of the test are highlighted on the result graphs. For ease of use, double tapping the main braking gauge duplicates the Start / Arm / Cancel button. General app options and vehicle options are available from the Settings screen. The app uses a combination of GPS, accelerometer and other sensors and is only accurate when the device is operated correctly and all sensors are receiving suitable signals. Please note that continued use of GPS can dramatically decrease battery life. This app is designed for use off-road and any brake testing should only be performed off the public road network. At all times you must comply with all traffic regulations applicable to your location.

The manufacturers can accept no liability for any injury, loss or damage which may occur while using this app. Policies EULA: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy: https://braketest.org/privacypolicy/

Verdict
The clearest difference is in-app purchases: JT Clock at none against BrakeTest's 3. JT Clock also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.6). BrakeTest's advantage is update cadence (fortnightly vs every 5 months). On price and ads there is nothing between them.
