** PLEASE NOTE THAT FOR NOW, MINDSTRETCH IS OFFERED ON A B2B BASIS ONLY. IF YOU ARE INTERESTED IN USING MINDSTRETCH, PLEASE ASK YOUR EMPLOYER TO CONTACT BIORICS AT INFO@BIORICS.COM** Mindstretch by BioRICS is the number one app to monitor mental energy use and mental recovery on a daily basis. Did we say β€œnumber one” ? Well that’s easy because there aren’t any other apps able to measure mental energy use and recovery. Our method has been developed by top scientists over many years and is one of a kind! Mental energy use, in some cases also seen as β€œstress” is certainly not a negative thing. We all need mental energy to focus on our work, family, friends and daily tasks. However, we also need to recover. The more energy we spend, the more recovery is required. In the long run, mental energy use and recovery need to be in balance. Mindstretch makes this information visible in easy-to-read graphs and overviews. Mindstretch is based on state-of-the-art bioresponse algorithms that are based on solid scientific research and measure the unique characteristics of your body. Every human body is unique and individually different. This is exactly what makes Mindstretch different from all other wearables: no one size fits all, but individualized measurements that also take into account your physical condition. Try it and you will see: Mindstretch reveals what your body already knew. Sometimes you also knew it yourself and sometimes you’ll find out that mental energy use is not necessarily associated with negative emotions or stressful situations. Also positive and joyful events such as socializing with friends, require mental energy. Mindstretch helps you to discover which activities provide energy and you will enjoy doing these more regularly to stay healthy and build resilience. Mindstretch for companies includes automated feedback and advice but you can also opt for a professional coach to take a look at your data. Don’t like that idea? Simply don’t apply for this option. Mindstretch is a fully private tool and all data remains anonymous unless you decide yourself to disclose your data to a coach or caregiver. Would you like more information about how we care about your personal data? Please check our Privacy Statement.
