The modern way of life, roughly summed up by working with a computer, watching TV and driving a car, forces us to sit "excessively". Which is not healthy. At the same time, in a busy schedule, it is difficult to keep track of how physically active we are during the day. That's why the Human app is here, which uses sensors in the iPhone to record every movement we make (walking, climbing stairs, riding a bike, running,...) and encourages us to be physically active for at least 30 minutes a day .
