Virtual personal trainer provides real time audio feedback

The app is powered by patent pending AI-powered motion tracking technology and uses just a smartphone (no additional hardware is required). It is like having a personal trainer at home - without having to go to the gym - and is democratising access to professional physical training and wellness feedback worldwide.

The Kaia Personal Trainer app has been developed with physiotherapists and fitness experts. It combines AI-powered motion tracking technology and personalised training to offer a customised full-body workout featuring a variety of exercises, including the side plank, bridge and reverse crunch.

To activate Kaia Personal Trainer, users stand seven feet away from their smartphone camera and begin exercising with video instructions. The app tracks physical activity with a 16-point system that compares the metrics of actual movement against ideal movement, including the relative positions of limbs and joints, and the angles between them. Kaia Personal Trainer counts the number of reps and provides users with instant, personalised real time audio feedback, advice and encouragement to improve fitness and performance.

Kaia Personal Trainer covers all relevant body parts and muscle groups, including the lower back, core, glutes and hamstrings. The AI-powered motion tracking technology adjusts the difficulty level and exercise based on the user’s feedback - and is particularly suited to those with little experience or training who want to integrate exercise into their lives in a mindful way.

Maximilian Strobel, Head of AI Lab at Kaia Health said: “Kaia Personal Trainer is a full-body workout in your pocket. It uses tech to offer you the experience of a personal trainer anywhere, with real time performance metrics - without the expensive personal trainer fees. The app puts users in control of their exercise performance with a virtual personal trainer which accompanies their every step.

"This fosters more intimate connections, establishing a relationship by becoming a part of their everyday routine and integrating with their fitness goals. We’re incredibly excited by our patent pending AI-powered motion tracking technology and virtual personal trainer as it has the potential to democratise access to a sustainable wellness feedback and fitness training worldwide.”

Commenting on the technology behind the Kaia Personal Trainer, Achilleas Georgiadis, Principle Deep Learning Engineer at Kaia Health, said: “Up until now, specialised hardware like a Microsoft Kinect was required to track the human body. We remove the need for costly hardware using advanced Deep Learning and Machine Learning algorithms and optimised them for mobile. This enables us to track the human body in real time using only the hardware of the smartphone - hence democratising access at no additional cost.”

Kaia Personal Trainer is available on smartphones and tablets (iOS 12 only) and can be downloaded via the Apple App Store. The technology will be released on Android in Q2 2019. The first seven days of the programme are available free within the free trial offer. In the US, the Kaia Personal Trainer app costs $29.99 for three months afterwards. The app is currently still free outside of the US.
