The progressor is a dynamometer / load cell that connects to your smartphone via Bluetooth to provide accurate load readings. The product is used by climbers to measure finger strength and by physiotherapists for rehabilitation exercises and isometric testing. By testing your strength on a regular basis you can see how you progress. It can e.g. be used to measure endurance, peak force, or rate of force development. Or if you wonder how far you are from doing that one arm pull-up, you can use the Progressor to measure how much help you need from the supporting arm. A free app is available for iOS and Android. In case you want to write your own code we provide an open API for communicating with the Progressor via Python or your preferred programming language. Sampling frequency: 80Hz.
