Lift Tester vs Alpha+ Usage & Stats

KLEEMANN Lift Tester is a free app that uses the sensors on your iOS device and special algorithms to measure the acceleration, velocity, jerk, distance and noise, i.e. the quantitative measures of a lift's ride quality. Version 2.0 is a complete redesign and rewrite of the app, and takes advantage of the latest hardware and software features of iOS devices. The app is good for casual measurements of elevator ride quality, especially with the aim of comparing different traction technologies or of assessing the evolution of ride quality of a specific lift over time. Disclaimer: You are using this app on your own risk! KLEEMANN SA explicitly disclaims any responsibility in case this app is used in lieu of specialised instruments! Please refer to a specialist for a professional measurement of ride quality.
