An accessible smartphone-based experimental set-up for measuring a spring constant is presented. Using the smartphone ambient light sensor as the motion timer that allows for the measurement of the period of oscillations of a vertical spring-mass oscillator we found the spring constant to be 27.3 ± 0.2 N m-1. This measurement is in a satisfactory agreement with another experimental value, 26.7 ± 0.1 N m-1, obtained via the traditional static method. © 2018 IOP Publishing Ltd.
