Kaia has developed a motion-tracking workout app that remembers which repetition the user is on and offers real-time feedback.

The Kaia Personal Trainer app that is developed by the Munich-based digital therapeutics start-up offers the skills of a personal trainer "at your fingertips in the comfort of your home."

Kaia Motion-Tracking App Features

With Kaia motion-tracking app, there is no need for any piece of equipment. It will only require the phone's camera to track the user's workout, although, some would still opt to use a fitness tracker.

Moreover, it gives real-time audio feedback on the user's exercise performance. It also automatically counts the number of correct repetitions.

How Kaia Personal Trainer App Works

How does the Kaia Personal Trainer app work? The phone should be positioned upright on a table or against a wall. The user must keep a distance of about 7 feet away (2.13 meters) or when the body becomes visible on the smartphone's screen. Whenever the app is ready, the user is greeted by the virtual personal trainer called Kaia, who will be the guide throughout the exercises.

Once the exercise starts, the app contrasts the pose of the user with the ideal predefined pose. Then, it compares positions and angles of limbs and joints.

During the exercise, Kaia gives real-time audio instructions that encourage the users to achieve the ideal exercise pose. The app will also modify the difficulty level and exercises based on the user's feedback.
