Our subscription gives you access to the Pro version for an annual fee of €10. This includes an additional music set (Modern), a training analysis and motivational messages. For the training evaluation, a basic measurement is carried out at the beginning. You walk at your usual pace for 30 seconds. This value is then used to assess your training success. You can view the average swing results of your training sessions in a clear graph. Here you can track - even over longer periods of time - how your arm swing behaviour and therefore your walking function is developing. These values can be sent as an email via a report button (e.g. to your doctor). Your swing values are stored permanently on your smartphone. Even if you don't have an active subscription. You can also set yourself a personal weekly target (e.g. 3 times/week). After training, you will then be informed whether you have reached your target.
