In the near future, people will need immediate analysis of their physical condition. They will be more real-time aware of their overall health. This is a new dimension of immediate facts, clearly presented, that will give them new opportunities to challenge themselves and learn more about their physical well-being. The TE3 is called a smart stick because it uses sensors to precisely measure body movement. Real-time data from the stick monitors body movement during exercise in a very precise way. It's revolutionary as well as simple and effective. The TE3 Pro application makes data analysis and transforms this information into easily understandable visual form. The stick also guides the user to do the movements correctly through vibration impulses. This also increases concentration and the awareness of our body motion. A digital training stick that analyzes body movements in multiple dimensions during training. Real-time feedback is no longer the future. It's here and now. It's TE3. Minimum system requirements: 3GB RAM iOS version 12.0 or higher Learn more at www.te3mobility.com
